Testing the Bionic Eyeball

I’ve been wearing contact lenses for many years. Whereas I dislike wearing glasses, I love contact lenses which seem to be very comfortable for me and give a better all round result. One slight drawback with contact lens distance correction is that age eventually make one need help with reading as well. Reading glasses over the top of the contacts is one perfectly reasonable solution but, for a couple of years, I got decent results using technology advances and wearing bifocal contact lenses. These I found to be fine when the difference between my reading and distant prescriptions was moderate. However, with increasing age comes an increase in the prescription difference and I found the clarity of my distance vision to be a little compromised – somewhat less than crystal clear. Given my love of nature, I really wanted as much clarity as I could get and reverted to simple distance lenses with reading glasses over the top as required. Better. The compromise in distance clarity was one of the main reasons that I rejected the idea of a multi-focal lens implant.

So, here I was, on the Friday morning following my surgery, with my new cataract-free bionic right eyeball equipped with a toric lens implant. The design objective of this lens is to get my right eye prescription “as close to zero as possible” and correct my slight astigmatism. We’ll know how close the medical gurus got to that in a few weeks time. Now, however, it was time for the great unveiling – I could remove my Long John Silver eye patch. Ah, the other thing I had to do was to open my eyelid which was closed under said eye patch. It was a little gummy round the lashes but a swift rinse fixed that. Eureka, I could see! Not only that but I could see clearly across the street and down the garden into the trees. Well, I could that with my new bionic right eye – my old natural left was still short sighted, of course, but I had no veil across my vision, though I could tell my left eye was out of focus.

So, one short distance eye and one long distance eye. I have a cousin who has had both eyes freed of cataracts and she has chosen deliberately precisely this fsormat. In fact, it was something suggested by Mr. Optician using contact lenses a few years ago but I never tried it. Now I was trying it. Turn on the computer – marvelous, I can read the screen with my left eye and see across the street with my right eye. In fact, reading the screen with just my left eye is pretty much what I’ve had to do for the last two years anyway since the right eye was veiled by a cataract. So, life’s not really any different with close work. Since I’m left eye dominant, the distance vision in my right eye doesn’t really encroach. When it comes to distance vision, my left eye being out of focus does encroach but it isn’t bad. Hey, this could catch on.

As advised, I spent Friday taking it easy and getting used to administering two eye drops four times a day. One is an anti-inflammatory, the other an antibiotic to guard against infection. Since it’s pollen season and the irritating (read ugly conifer) tree in our front garden is coating the world in yellow dust, I stayed indoors on Saturday as well. On Sunday, though, Carol wanted to go and count orchids at our local Sandhouse Lane Nature Reserve so I decided to go along to give my new vision a test drive on dragonflies.

J01_2713 Azure DamselflyFor the first time in weeks, I put in my old left contact lens. So this is what vision used to be like. It’s amazing how quickly one forgets. My left eye was now in focus at distance too and, with the now clear right eye, the world looked great. Assessing distance from the kerb whilst driving was certainly much better. Not being a sunny day, Odo activity was a little subdued but as soon as we walked in to the reserve I began spotting Azure Damselflies (Coenagrion puella) on leaves in the bushes. Seeing them stationary has been a bit of a challenge, of late. Best of all, when I disturbed them and they started flying, I could track them instead of losing them in the bushes. Great!

IMG_9465 White-legged DamMy new eyeball found me a new species for this year, too. Sandhouse Lane is graced with a colony of White-legged Damselflies and I spotted about six, all of which were females, I believe. I think it’s common for the first emergence flush to be a batch of females in several species of Odo but don’t quote me. We moved on and I kept revelling in my ability to see small critters better than I could remember. We even found a new species to me for this location in the shape of three Red-eyed Damselflies, again all female, though they didn’t seem particularly cooperative vis-a-vis photography. No dragonflies, though, just damsels.

_MG_0383Meanwhile Carol was wandering around muttering, “125, 126, …” as she counted the population of Common Spotted Orchids (Dactylorhiza fuchsii) in Sandhouse Lane. Final count reached about 175 and she found this one particularly nice example that was advanced enough to be photogenic. Supposedly, last year there were 750 so we may have a way to go yet. We may need help counting, too. 🙂

Next Thursday I get my post-operative check up with Miss Consultant when we should find out what she thinks. Until then, however, and on first impressions, I’m very happy.

Under the Knife Again

Yesterday I was out with the BNHS (Bedfordshire Natural History Society) chasing dragonflies with one and a half eyeballs for what I hoped would be the last time ‘cos today I was due in surgery for cataract removal and a new lens implant. One of the things Miss Consultant had mentioned that I should think about, in addition to choosing my preferred kens type (long-distance/short distance/multifocal), was the choice between having the procedure performed under local anaesthetic (the norm) or general anaesthetic. She’d suggested I tell the Optometrist when he measured my eyeball to order the lens. In fretting about which lens to choose, Muggins forgot the bit about the anaesthetic and Mr Optometrist didn’t ask. Yesterday I got a phone call telling me it would be general anaesthetic which was noticeably more expensive but probably no bad thing. In truth, I’d probably have picked local but I didn’t fancy squirming about conscious while Miss Consultant was messing with my eye.

Today Carol drove me to the Chiltern hospital at Great Missenden to have my nice new long-distance lens fitted. I was handed some paperwork about a “fixed price package”, the fixed price in question being £3385.00. For some reason, I read all the writing and panicked slightly when seeing something about the procedure being to “fit a multifocal lens” which I had specifically rejected. Miss Consultant assured me that she was in fact, fitting a toric long-distance lens and that the paperwork was just designed to get the price right. Hmm, apparently there aren’t enough options in their computer system. Toric lenses (to correct astigmatism) have to be oriented precisely so I got a little local anaesthetic and Miss Consultant set about marking up my eyeball with something like a felt tip pen (odd sensation) and a sharp pointy thing (worse sensation). She the drew a big red arrow above my right eye to make sure she cut open the correct eyeball when she next saw me in the operating theatre! Very reassuring! The price list for this operation mentions “from £2700.” Maybe the toric lenses are more expensive but I think most of the price difference was down to the general anaesthetic. Well, better a pain in the bank account than a pain in my eye.

Up to the ward to be prepared. Preparation including trying to fill out a lengthy health questionnaire while a constant stream of folks came in asking other questions, explaining where my theatre gown and knockers were, etc. Had I finished the questionnaire yet? “Well, no, people keep distracting me.” Then a nurse appeared to administer three typed of eye drop to dilate my pupil and Darwin knows what else. Had I finished the questionnaire yet? “Well, no, I’ve been being given three sets of eye drops four times each at 10-minute intervals.” The male nurse with the questionnaire decided to sit with me a fill it out for me in a question and answer session. The time concern was because I had a theatre slot to make. It’s a bit like aircraft and their take off slot at Heathrow airport. Miss it and you’re stuck.

At last, time to don one of those weird gap-all-the-way-down-the-back theatre gowns and some even weirder disposable underwear. How do you do those gowns up? I couldn’t reach either of the two tapes. When a nurse returned I got her to assist in fastening my high-fashion couture.

When I had my prostatectomy which is major surgery, I was a little surprised to have to walk all the way to the operating theatre. I thought I’d be wheeled along on a trolley but not a bit of it. This time, with what is really minor surgery, a trolley came to collect me and I was wheeled along to the theatre. Go figure! Was this because I was paying for this? Well, no, I think it was because my eyeball was now dilated and wide open, set to something like f1.4 in photography terms. They didn’t want me tripping because I had no depth of field.

In the wings of the theatre the medical team began putting masks and monitoring devices on me. The monitoring device caused a problem, mainly because I’d had nursey fasten my theatre gown at the neck for me. Mr. Monitor expressed surprise and undid it again. Whoops, maybe that’s why they’re impossible to do up yourself.

I lost an hour. The next thing I knew, I was in the recovery room with a Long John Silver eye patch.

I got another trolley ride back to my room where my frequent visits continued to monitor my vital signs and make sure I was recovering sufficiently to be sent home. Carol , my ambulance driver, turned up to sit with me. My oxygen saturation level was a little low for a while, only 94%, but stopping talking to Carol so I could do a few deep breathing exercises stuffed it back up to 96% and, once I’d peed – hospitals are very keen on bodily waste functions, I’ve noticed – I was allowed out. A nice nurse told me, “keep the eye patch on overnight and just take it easy tomorrow”. I gesticulated, turning my right hand round and round vertically in circles. Quick on the uptake, the delightful nurse added, “and for the following week”. What a lovely lady. 😀

The eyeball felt a little scratchy on the way home. I wondered if this was because I was looking around at the scenery. I shut my eyes to avoid looking and things got more comfortable.

Sleeping with the eye patch might be interesting.

A Salopian Weekend

Being an Odo-nutter, a self-confessed dragonfly anorak, I maintain a list of the species I’ve seen in various countries. Of most interest is, perhaps naturally, that of the home team, the Odonata of the UK. In Britain’s Dragonflies, Messrs Smallshire and Swash list 44 breeding species though I would tend to argue against one of those being included: the Yellow-winged Darter (Sympetrum flaveolum), of which the BDS says this.

Irregular migrant but may occur in large numbers (1995, 2006). Has bred after major influxes (e.g. Chartley Moss, Staffordshire, in 1996), but colonies do not persist.

British Dragonflies says something similar. Personally, I’d leave it in the separate migrants/vagrants list until such time as colonies do persist.

So, my list is actually 43. There are four species that occur only in locales “where angels fear to tread”. I’m thinking particularly of the Irish Damselfly (Coenagrion lunulatum), which I will never see in our territory since I am not prepared to go anywhere near Ireland, together with the Azure Hawker (Aeshna caerulea),  Northern Damselfly (Coenagrion hastulatum) and Northern Emerald (Somatochlora arctica), all three of which are limited in range to Scotland which, following last September’s disastrous trip weather-wise, I’m not about to hurry back to tick off, either. Fortunately, those four are at least potentially available in France.

That leaves me with four target species that I’m prepared to find in the UK. Two of my missing four species are very localized in their territory but at least their locales are civilized. One reason that I haven’t yet seen them is that both have a main flight season in June, when I am habitually swanning around France. This year however, is different because I am “stuck” in the UK awaiting my cataract operation. My enforced stay has its compensations, however, in that it enables us to go in search of them.

Last weekend, we had booked in to a campsite just outside Shrewsbury to search for the very habitat-specific White-faced Darter (Leucorrhinia dubia). This character is dependent upon peat bogs with floating Sphagnum Moss, 95% of which habitat we have contrived to destroy in the UK. It is now rare and localized but there is a thriving population at Whixall Moss about 12 miles north of Shrewsbury, Shropshire. The icing on the cake was that this was forecast to be a largely sunny weekend. During our 120-mile drive up on Friday, we got a phone call informing us that my cataract operation would be on the following Thursday (13th June). Hoorah! Happy camper.

J01_2830 campsite Downy EmeraldThis was my first trip to this part of the country and we lucked out in that the campsite proved to be excellent. In a second stroke of luck, the campsite presented us with some on-site Friday afternoon entertainment in the form of a flooded quarry. Here we found eight species of Odos the most interesting of which was a Downy Emerald (Cordulia aenea). Like a good little Odo observer, I submitted my sightings to the Shropshire county recorder and it seems that my Downy was a first at this site. Good job I got a photograph as proof.

J01_2883 White-faced DarterJ01_2880 White-faced DarterOn Saturday we went to the hallowed ground of Whixall Moss in search the main quarry of our trip, the White-faced Darter. En route we called in to another moss, Wem Moss, thinking that we might find some sundews for those with a botanical bent but our attempt proved unsuccessful, the entrance track being something of a quagmire and, in all probability, the sundews being yet to appear, anyway. Fortunately, Whixall Moss was much more successful. Here, not only did we find the White-faces in reasonable abundance, but I also bumped into another couple of other dragonfly enthusiasts from the UK Dragonflies website, who were up on a day trip from the Bristol area. Though the White-faces tend to keep low and can be tricky to snap, we had a bit of nature photo-fest together.

_MG_0303 Quantum LeapOn Sunday we took a break from dragonflies and went in search of more cultural entertainment in Shrewsbury. Shrewsbury is in a large loop of the meandering River Severn, which I now know to be the longest river in Britain, and is the home town of Charles Darwin. It’s difficult to get away from either when visiting Shrewsbury, not that one should want to, I’d say. We’d really lucked out for this weekend and our third day of sunshine showed off Shrewsbury to good effect. On one bank of the Severn, we found this memorial, cast in concrete, to Charles Darwin intriguingly entitled Quantum Leap. A little further along the riverside a festival of some kind was just beginning to warm up with a zumba demonstration by a group of energetic ladies.

So, even though the temperatures were kept a little low by an easterly airflow, our three day sunny weekend will probably go down as this year’s summer. It’s been a long time since I was away for just a weekend but I can’t remember enjoying one more. Mind you, I was getting Billy withdrawal symptoms. Not only did we get to walk and sit outside but we found our intended quarry. That all adds up to it being a great success, I’d say.

A Hairy Spring

This spring has been different. For one thing, it’s been a lot colder than normal – the coldest for 50 years, I think it is now said – which has delayed nature all round. The emergence of long-awaited damselflies after what seemed like an interminable winter was certainly late. Damselflies are the first Odonata to appear but shortly after, a few dragonflies, the big boys, do begin appearing. One of those is the Hairy Dragonfly [BDS name] or Hairy Hawker [preferred by Dijkstra/Lewington … and myself, for that matter], Brachytron pratense. It’s a so-called mosaic hawker, those with a dark abdomen with inlaid coloured spots/markings. If you see a mosaic hawker zooming about in May, in the UK that is, it’s almost guaranteed to be a Hairy. They don’t settle particularly often so they are a tricky species to snap.

IMG_9475 Hairy Hawker ovipositingI know my fascination with Odonata began only about four years ago, but I went for three of those years with just a single Hairy Hawker spotting, complete with a crappy photo of it. My subject was an ovipositing female and it was definitely a grab shot but I really should have been able to do better; it’s not as though they bounce up and down, like some species, while they oviposit, darn it! Just for a laugh, here’s that picture. Lose 10 points JC.

Though the weather this spring has been absolute pants, we will all have noticed, with much relief I suspect, that we are currently enjoying a very welcomed spell of settled weather with a good amount of sun. We are still in the grip of largely easterly/north-easterly winds that have a distinct chill to them but it is very pleasant and one heck of a lot better than anything hitherto. I’m quite certain that our wildlife will have been breathing collective sighs of relief.

First of all, on one of our earlier sunny days when we went exploring Roxton, We spotted two Hairy Hawkers and Carol managed to snag a grab shot of one settled in a rather inaccessible position. It, too was a female and, though awkwardly positioned, was a hell of a lot better than my historic, blurred ovipositing female.

A second encounter came last Sunday, three days ago, while we were exploring Harrold-Odell Country Park for the first time. Here, yet another female Hairy Hawker settled in a tree beside us to devour a hapless teneral damselfly. She was not obscured, at least from the best angle, and we now had a very good picture of a female Hairy.

Our third encounter happened today when we risked life, limb and car by visiting the Blue Lagoon in Bletchley. That might sound like a romantic name but the reality is quite different. It may not be quite as bad as I make out but the Blue Lagoon’s surroundings are, shall we say, on the rough side of civilized. It’s a decent enough habitat but is on the doorstep of a questionable housing estate and comes complete with a traveller encampment (I won’t dignify them by calling them Gypsies) at its southern end, very near the secluded car park. It does not engender a feeling of calm and security.

J01_2785 Four-spotted ChaserJ01_2790 Four-spotted ChaserShortly after we bravely parked in said secluded car park, we were stalking a couple of Four-spotted Chasers (Libellula quadrimaculata) flying and perching in a sunny inlet on the first lake. Yet another Hairy Hawker flew in, sniffed around the reeds as they do, then flew back out. We amused ourselves with the Four-spotted Chasers, which were our first of this season.

J01_2792 Hairy Hawker maleJ01_2793 Hairy Hawker maleWe moved a few yards further round the lakeside to another access point. I’d peered at the reeds at the edge of the lake itself and seen nothing when Carol announced that another Four-spotted Chaser was settled in an accessible position. I grabbed another shot – you can never have too many Four-spotted Chaser pictures. Then to my astonishment, we spotted a Hairy Hawker perched on a sapling a foot or so above the ground. Apart from needing to avoid a few blades of intervening grass, it couldn’t really have been any better. It sat for some time while I snapped away. I could see this one was my first ever male, so we now had a matching pair for the collection. Excellent!

We’re usually in France for June but this year I’m “stuck” here waiting for a cataract operation. Still, it gives me the chance to seek out UK species that I usually miss due to my absence. It’s not entirely absence that makes the Hairy Hawkers difficult, though, ‘cos I’ve seen other respected dragonfly enthusiasts say they’ve been waiting years for a decently settled Hairy. So, I consider myself very fortunate this hairy spring.

Maybe I’ll have to stay here more often? Nah!

Orchids for a Change

This ridiculous spring is messing up all manner of wildlife-related issues. Many bird species time their breeding to take advantage of an expected bonanza of flying insects. When those insects are not present in sufficient numbers, nestlings are prone to perish ‘cos the adults cannot feed them successfully. I can just imagine the effect on migrants flying in from Africa, starving after the journey, and wondering where the hell the missing flying insects are. With my particular interests, I feel the lateness of the spring most accutely when it comes to dragonflies and their emergence/appearance, and with the dearth of butterflies.

Local organisations devise calendars of activities for the coming year well in advance, so they can get them into print and publicized, based on expected norms. Today we attended one from our own Bedfordshire Natural History Society, a walk around Pegsdon Hills in search of orchids, particularly one new to us, the Fly Orchid (Ophrys insectifera). I’m no botanist but it seems that orchids like chalk soils and Pegsdon Hills lies at the extreme eastern end of the Chilterns. We met at 10:30 AM. On this amazing 1st June, most of the 19 attendees appeared to be wrapped up for winter. As the cool morning air chilled me through my shirt-over-t-shirt combination, I began to wish I was, too.

Our leader was on home turf and knew where our main target species were. He did, however, warn us that several species we would have expected to admire would not be seen yet because of the lateness of the season. Since orchids not yet in flower are very easy to trample underfoot, he asked us to be wary about where we trod. In the curiously named section known as Hoo Bit, there were several Fly Orchids in bloom and also some White Helleborines (Cephalanthera damasonium) which were just beginning to show flower. Others, though, particularly those in shadier locations, were showing flower spikes but no actual flowers as yet. Another orchid species in this chalk grassland reserve was the Common Twayblade (Listera ovata), most of which were not in flower yet either.

Fly OrchidWhite HelleborineCommon TwaybladeI may not be a botanist but I do find orchids interesting, so even I had a go at snapping them. After all, there weren’t any flying insects for me to concentrate my efforts on. Naturally, though, our floral specialist grabbed better shots than I and here’s Carol’s collection of the three orchids of the day, including a Common Twayblade against all the odds. Personally, I think I’d rename the Fly Orchid as the Jamiroquai Orchid; the top of the flower looks just like the strange headgear favoured by Jay Kay. 🙂

We did see a few butterflies but they were not at all keen on flying. The first was a Dingy Skipper which had chosen to hitch a ride on the front of one our group’s trousers. I also noticed two or three Small Heaths which seem to have appeared in the last few days.  Our leader had clearly done this kind of thing before and even he expressed surprise about the almost complete lack of butterflies, saying that in a normal year he’d “be beating them off with a stick”.

This is everything but a normal year.

Taking a Damsel for Lunch

I’ve maintained a “to be visited” list of potential dragonfly haunts for some time. One of those is Harrold-Odell Country Park but, as reported in A Break from Paper Hanging, our recent spell of settled weather coincided with a bank holiday so I avoided it in favour of quieter haunts. However, with further Odo-friendly weather today, albeit with a wind that still had a chill to it, I just couldn’t resist my inaugural visit, even though this would mean braving Joe Public, Joe Public’s uncontrolled rugrats (controlling rugrats is clearly very unfashionable in the UK these days) and Joe Public’s even less controlled dogs (“down Rover, don’t jump up people” – how many times have they said that?).

The park lies in the north of Bedfordshire between two villages called Harrold and Odell. Ah ha! It took us about 45 minutes to get there, via Tesco at Kingston in Milton Keynes in search of an HDMI cable with a bendy head, which we found. An overflow car park was open and, Just driving into at, we were scaring up clouds of teneral damselflies which had to go unidentified but were either Azure Damselflies (Coenagrion puella) and/or Common Blue Damselflies (Enallagma cyathigerum). We identified both, later. Even the overflow car park was approaching full and there were nearly as many teneral Homo sapiens as there were teneral Enallagma cyathigerum. I must say, though, that the place proved to be a pleasant surprise, very nicely done and essentially free, though there was a suggested £1 donation for parking which I’m more than happy to pay for such a facility. Donations are a nice way to do it.

J01_2735 Common Blue Damselfly maleHOCP has a big lake, Grebe Lake, which we sat beside to eat a chorizo and tomato sandwich while we watched the constant flutter of rising tenerals again. You really couldn’t take a step here without scaring up someone; there were hundreds of them. Here’s what some of the lucky ones of these will turn into, a fully matured male Common Blue Damselfly. I really don’t have any idea of the strition rate for teneral damselflies – interesting thought.

J01_2726 Banded Demoiselle maleAfter a brief lunch we headed into the “wildlife sanctuary”, a wooded wetland area, which was is also a blessed sanctuary from dogs. Excellent! We added loads of Banded Demoiselles (Calopteryz splendens) to our count and spent some time watching a suspected Hairy Dragonfly/Hairy Hawker (Brachytron pratense) zoom about waiting for a landing which, typically, never occurred. There was also a lone female Blue-tailed Damselfly.

Leaving the wildlife sanctuary, we struck out across a field of cow pats (avoided) to the Great Ouse which snakes borders the southern side of the park. Here we found a pair of Large Red Damselflies (Pyrrhosoma nymphula) ovipositing though we didn’t see any others, somewhat curiously. The Ouse was clearly not navigable at this point, the middle being blocked in various places by clumps of reed and other emergent vegetation, much loved of dragonflies. There were a few sparse patches of lily pads near the river bank which were being occupied by several Red-eyed Damselflies (Erythromma najas), in their habitual manner.

J01_2738 Damselfly exuviaWith the day’s species count standing at a traditional seven – I have several sites in this vicinity with a count of seven – we began making our way back towards the overflowing car park. Oh well, just a quick extra look along the shore of Grebe Lake, then. 🙂 The lake itself looked relatively quiet but I did spot a damselfly exuvia on one of plants. Given the amount of tenerals going up throughout the afternoon there must have been lots more but they seem pretty difficult to spot. Where blue-type damselflies are concerned, they are also difficult to identify with any degree of certainly, apparently. This one is clearly that of a damselfly because it still has caudal lamellae attached – gill like structures at the end of the tail/abdomen.

J01_2740 Hairy Hawker at lunchJ01_2742 Hairy Hawker femaleThe highlight happened following my exuvia interlude. Another Hairy Hawker shot past us. Shortly it returned flying more slowly and looking somehow different. It settled in a lakeside tree just above our heads. At first glance Carol wondered if it had formed a copulation wheel with another. However, once settled we could see that it looked different because it had one of the teneral damselflies dangling from its mouthparts. Its lunch main course is a female damselfly – you can see its never-to-be-used ovipositor in the photo (left) but I can’t tell the species. The angle caused a twig to blur some of the dining subject, unfortunately, but I wanted the shot for interest. It took just a few minutes to munch everything but the wings. I moved round to get a better – less macabre? – angle which is the much better photo (right). This was my first ever decent chance for a Hairy Dragonfly photo shoot so I was very content with the day’s work.

Harrold-Odell Country Park proved to be a less intimidating place that I feared. I will certainly return to see what species the later season brings.

More Medical Decisions

I made it into my 50s with hardly ever seeing the inside of a hospital. Then my medical fun started with the eventual discovery of prostate cancer. That got me started on medical decisions when I was offered four choices of what to do next, one of which was nothing and three of which offered some sort of fix. I found that decision very easy – surgery, rip the rotten thing out. I had my  radical prostatectomy [just making sure I can still spell it] in December 2010. Subsequent PSA tests will continue for about 10 years but, I’m pleased to say, thus far indications are good, i.e. the readings have been effectively zero. I’m very confident that I made the correct decision.

In my first post-operative year, 2011, I began to notice a slight fuzzing of the vision in my right eye. Initially, I was really only aware of it whilst reading a book at night. At my next yearly eye test, I mentioned it to my optician. Yes, I had the beginnings of a cataract developing. Oh joy! Development of these things, I was told, could be slow or could be fast or, indeed, somewhere in between. Well, that pretty much covers all eventualities. Mine was not yet anything like bad enough to be referred for treatment so we’d wait and see how things went.

I waited throughout 2012, still managing to track and photograph insects, as is my wont. Fortunately I happen to be left eye dominant and my left eye was still working properly. 35mm camera design is actually better for right-eyed people but that’s another issue. I use mine with my left eye and all continued to be well. There were two main reasons for what may have been protracted waiting:

  1. I didn’t want to get referred and go through the lengthy wait for me to percolate up to the top of the NHS list, only to be told to go away ‘cos my cataract wasn’t yet severe enough (the old term “ripe” sprang to mind) to be operated on;
  2. I’d eventually have to choose between a long-distance lens implant or a close-focus (reading) lens implant and I was by no means certain as to which I’d prefer (I was currently short-sighted in both eyes and used to being so).

I used the waiting period to discuss things with Mr. Optician and talked about the option of going private. Mr. Optician, who is also a personal friend, seemed less than keen on the private route for me, largely because, should any corrective treatment be necessary following the operation, that would also have to be done privately and costs could mount up considerably. He had one such patient who had already spent over £20K, though such things are mercifully rare. I should point out that, being retired, private health insurance is not a luxury I have. “What’s it cost, anyway?”, I enquired. “Oh, about £2000, I think”. “And how long would the wait be?”, I asked. “About 6 months on the NHS but you could have it done next week if you went private”, was his answer. [Remember that.] So, I continued to wait.

Then came our seemingly interminable 2012/13 winter. Only with the late beginnings of what we rather laughingly this year call spring, did I really notice that my right eye had deteriorated noticeably. Most of my winter tends to be spent inside doing close work rather than outside viewing the distant countryside and critters. In this situation, the effect of the cataract was less noticeable. Also, deterioration is actually very gradual, unnoticeable on a day to day basis; you just get used to it. Driving gave me one clue, if I covered up my left briefly. I could see the yellow of number plates of cars I was following, at a safe distance of course, but almost nothing of the black characters upon them. I wasn’t, however, experiencing any light scatter as described by some sufferers when driving at night. I really noticed when I started searching for critters to photograph again. “Surely I didn’t go through last summer like this”, was one thought that sprang to mind. The other thought was, “where did that damn critter go?” Now my cataract was adversely affecting my hobby; now I wanted it fixed.

The way the referral process works appears to vary by postcode. Where have we heard that before? Since I’m in Bedfordshire, my optician, in Buckinghamshire, apparently couldn’t refer me direct but had to send a note to my GP practice. That happened on March 14th. It can take 2 weeks or more these days to get an appointment at our GP practice but fortunately their eye specialist had two un-grabbed slots early the following week. I nabbed one and saw him quicker than expected on March 19th whereupon he referred me to a consultant. It’s a rubber stamp job, really, that just sticks a delay into the process.

Decision point: the NHS, bless it, is gloriously free but it’s a drawn out process and, worst of all, you have no way of knowing just how drawn out it will turn out to be. We had a 3-week trip to Spain coming up on April 24th, just over a month away. I could see an initial NHS consultation appointment landing on my doormat the day we left for Spain and my missing that appointment, thereby ending up back at the bottom of the pile after a second referral. I tried to phone to give them the dates of my absence but could speak only to the general appointments line at Stoke Mandeville hospital; apparently the person dealing with NHS ophthalmic scheduling didn’t take phone calls. The lady on the phone added that I had to work around them, not the other way around. OK, no concept of a customer but fair enough, I suppose, though I was just trying to save wasted time and a potentially wasted appointment slot. I also discovered that the NHS “was not hitting the 18-week target”. So, the six months or more on the NHS was looking like reality. I’m 60, for Darwin’s sake, I didn’t want to spend one of my precious summers, should one actually ever turn up again, twiddling my thumbs waiting, unable to book anything lest an NHS appointment letter land on the doormat while I’m away. I switched horses and elected to go private, mainly to get some scheduling control.

With a combination of my prevarication, our trip to Spain and Miss Consultant taking a vacation, I eventually saw her for my initial consultation on May 13th, after Spain. I could actually have seen her a few days before Spain (on April 18th) but we decided to wait ‘til we returned. That was a mistake and here’s why. The next thing that needs to happen following the initial consultation is to get some eyeball measurements performed to calculate the power of the lens implant required. However, contact lenses tend to distort the eyeball’s natural shape a little so I now needed to wait two weeks, without wearing my lenses, before seeing Mr Optometrist for those measurements. Had I known that from the outset, I’d have grabbed the one remaining appointment slot with Miss Consultant prior to Spain and used Spain as my 2-week eyeball recovery time sans contact lenses. A clear case of 20/20 hindsight. Never mind, Miss Consultant was about to go away on yet another vacation anyway, during which time I eventually saw Mr. Optometrist on May 28th.

The measuring of the eyeball is when you need to make the final decision as which type of lens you want: close focus, long distance or new-fangled multifocal. (The latter is not approved and not available on the NHS.) I’d been put very firmly off the multifocal route by a Dutch acquaintance who had one fitted and hated it. Since I’m used to being short-sighted, my initial, maybe natural, inclination was to get the right eye matched to my left eye, continuing with my familiar naked eyeball reading and using contacts/spectacles for long sight correction. However, Miss Consultant thought she may have seen the glimmerings of a cataract forming in my left eye, too. Since I dislike wearing glasses, especially outside in the rain, maybe if I needed the second eye done in another two years or so, long distance eyeballs might be good. The interim time with one long and one short eye would certainly be interesting, though I have a cousin who has deliberately chosen that format. Now came Mr Optometrist’s input which confused the choice even more. It seems that calculating the required lens power, even after eye measurement, is not an exact science. This is because there are still unknowns. Apparently the lens in the eye is only about 60% of your focusing (I thought it was 100%) with the cornea doing about 40% of the focusing. I’m assuming that the use of the word “about” is the rub. It appears that their calculation must include some sort of average value somewhere in the equation rather than a precisely measured value. So, in opting for a long distance lens, Mr. Optometrist says things like, “we will try to get your prescription as close to zero as possible”. In other words, you might still end up needing glasses for fine tuning. So, if I might end up having to tweak my long sight anyway, might it be better to go for a reading prescription where the fine tuning would be the distance at which I held the book, then continue to correct for distance as now? Arghhh, I hate decisions!

Based on the possibility of needing eye #2 done eventually and being drawn to the possibility of avoiding glasses in the rain shoud I at some pooint be unable to wear contact lenses, with heart in mouth I opted for a long distance lens and trusted to luck. Mr Optometrist was going to disappear and calculate/guess at my prescription then order a long distance toric lens to correct my slight astigmatism into the bargain (don’t think toric lenses are available on the NHS either). Meanwhile Miss Consultant would be finishing vacation #2. Back at home, I was not at all confident that I had made the best decision.

Now, here we are at May 28th having been referred by the Optician on March 14th. I’ll cop for 2½ weeks of that delay because of Spain, and I’ll add another 1½ weeks for my initial prevaricating. So, that’s a month wasted by myself. it’s still taken six weeks though, some of which are Miss Consultant’s vacations. So much for, “you can have it done next week if you go private”.

Knowing my luck, my focusing percentages will be way off average and … well, we’ll find out when Miss Consultant returns again.

Isn’t aging a fun process?

Discovering Roxton

What had we done to deserve this, a second sunny day on a bank holiday weekend? At least, if you don’t live in the west of the country, it was sunny – the forecast seemed to be cutting the country in two – though it was quite windy, too. I’d seen some interesting dragonfly records being entered from a section of the Great Ouse river, which was new to me, so I absconded from the paper hanging once again and we decided to investigate Roxton, just south of the nastily busy black cat roundabout on the A1.

As ever with new ground, I had little information about precise location but we found Roxton itself, a quiet, sleepy little village, navigated a few single-track roads – grass growing down the centre of the road is always fun – and found an apparently suitable parking spot. In fact, it appeared to be the only suitable parking spot and it was empty. Maybe we’d succeeded in avoiding swarms of people on this bank holiday again?

J01_2656 Blue-tailed femaleA handy-dandy footpath sign indicating the direction to “Roxton lock” gave us a clue and off we set. A couple of Large Red Damselflies (Pyrrhosoma nymphula) flittered in some nettles beside the path. They were some way from the river but there are also a couple of seemingly private fishing lakes to the side which I imagine is where they emerged from. Continuing slowly, we soon added several Common Blue Dams (Enallagma cyathigerum), Blue-tailed Damselflies (Ischnura elegans) and a lonely (poorly positioned) Banded Demoiselle (Calopteryx splendens). The Blue-tails and Demoiselle were our first of this season so I was already a contented camper. Blue tails may be my favourite damselflies, largely because of the variety of colour forms of the females. This specimen is a very neat looking f. rufescens.

C01-0045-Hairy-Dragonfly-adAt a widening patch of sunlit nettles, Carol shouted the immortal phrase, “big boy!”. Well, what could she possibly have meant? It’s a good job the man walking his dog hadn’t been closer, sooner. 😀 The cause of her unseemly outburst was two dragons, which looked a bit mosaic to me as they flashed past at a rate of knots. Anything looking mosaic at this time of year had to be Hairy Dragonflies (Brachytron pratense). I’ve seen only one before in my short dragonfly career so excitement was high. The dragonflies split up so we followed suit. I chased one which promptly disappeared. Carol’s subject settled briefly but rather uncooperatively. However, she did manage a recognizable picture on her only-one-day-old, shiny new Canon EOS 60D, so well done to her.

J01_2665 Scarce ChaserJ01_2662 Scarce ChaserStaying with the nettle bed, more fortune arrived in the shape of an orangey dragon. I was beside myself now. It landed right in front of me as I stood in the nettles with trousers that were clearly too thin to offer protection. Nonetheless, I wasn’t about to miss this golden opportunity. I’ve seen only one female Scarce Chaser (Libellula fulva) before and she was half-way down France. This was my first UK example and she posed long enough for a clear plan shot, given a little getting stung and stretching by yours truly. Then she went further down our track where she posed for a good side view. Unbounded joy!

J01_2670 Banded DemoiselleJ01_2681 Banded DemoiselleFinally, we hit the river and found the mother-lode of Banded Demoiselles (Calopteryx splendens), where two males posed for an interesting combination picture. One seems to have a slight blemish on its wing but it wasn’t having any trouble flying and displaying. A female posed shining brilliantly in the sun, too.

Further down the riverside path we hit another mother-lode, of Red-eyed Damsels (Erythromma najas) this time. “Why just here?”, I wondered, as I watched them in the ubiquitous stinging nettles, getting stung yet again all the while completely missing the fact that here were the only lily pads in this stretch of the river. Duh! We counted about ten, though I’m sure there were more. I sagged a decent male and female specimen – they really are delightful damselflies – and I couldn’t resist a distant shot of the classic Red-eye on lily pad pose.

Retracing our steps, the sunlit nettle bed appeared to be now almost deserted. It’s all about timing, isn’t it? Either that or my trampling it to get an angle on a truly scarce female Scarce Chaser upset everybody.

Final tally was seven species which is pretty good for me at a new location and certainly not bad for a river location. 🙂

A Break from Paper Hanging

With Odo weather being as scarce as rocking horse shit this year, I’ve been using the depressingly bad start to the new dragonfly season constructively by redecorating the lounge. However, something went wrong with the UK weather pattern: whereas any usual UK bank holiday would be plagued by rain, perhaps because our current pattern is to be cold and wet, on this particular bank holiday Sunday, the rain ceased and the sun was forecast to put in a guest appearance. I wasn’t about to spend such a precious day indoors hanging wallpaper.  Fortunately, my paste bucket ran dry with two short but complicated walls still left to cover. 😀

There’s a country park at a pair of villages a little north of me that I would like to investigate. Since the two villages are called Harrold and Odell, the country park is imaginatively named the Harrold-Odell Country Park. It apparently has a lake, a “wildlife sanctuary” with wetland, and a stretch of the Great Ouse river flowing beside it. Oh, and it has a website, which is how I know this. Unfortunately, I spotted that it also is advertised as being “a great place to walk dogs” and as having “things to keep the kids amused”. There be dragons – probably best avoided on an uncharacteristically sunny bank holiday weekend when every day on the lead up has been crap. Fearing for my sanity amongst barking hounds and screaming rugrats, I left it in the “to be visited” category and opted for a few small local nature-friendly places with no family attractions whatsoever. It was a bit like looking for a campsite, really.

J01_2588 BBC femaleI kicked off with Flitton Moor where a small herd of cows had poached the edge of a pond into a mud bath. I was ill-equipped, not thinking wellies would have been necessary. Nothing was moving at first but, from the safety of the short boardwalk, I did eventually spot a distant damselfly rise and fly up and away on what I imagine was its maiden flight. Then a tell-tale flash of larger wings glinted in the grass just a little closer. My trainers braved the less muddy clods of mud and I eventually found a very teneral female Broad-bodied Chaser (Libellula depressa). My first true dragonfly of the new UK season. There was no way to get rid of all the obstructing grass but at least I got some sort of photographic evidence before she, too, disappeared in the same direction as had the damselfly.

J01_2602 Colourful combinationThe pond now appeared to be completely still so I tried the small stream, which looked deserted at first but where I was pleased eventually to find 6 Large Red Damselflies (Pyrrhosoma nymphula) and 6 Azure Damselflies (Coenagrion puella), two of whom were in tandem. Way to go! Here, I found a colourful combination of males of the two species sitting close together. Mostly they were disturbing each other, though.

Next to Duck End NR where our (Bedfordshire’s) first Large Red Damselflies are often recorded (1st May this year). I’ve only been there at the start of the season so seen only Large Reds there; I was hoping to add a species or two. I lost count of the Large Reds but it was well over 30; I figured it to be around 36 so the population is very healthy. I did see 6 Azure Damselflies, too, but nothing else.

J01_2625 Downy EmeraldFinally, with the clock passing 3:00 PM, I returned to my real home patch of Sandhouse Lane NR. Oddly, I’d forgotten its star attraction but I was reminded of it in no uncertain terms when, just a few yards in from the entrance, a fresh Downy Emerald (Cordulia aenea) landed in the trees beside me. It was too high to get a very good shot – not enough DoF – but here’s a recognizable one for the record. We’re lucky to have this outpost of Downy Ems and it’s great to see them. Regrettably, the suspected breeding pond is in a private fishing ground complete with security guard so the little darlings aren’t the easiest to observe – they have to fly out and over a fence/hedge or two. I spotted and/or disturbed four others but they present photo opportunities – not after I disturbed them, anyway. Other culprits here were 15 Large Red Damselflies, 6 Azure Damselflies (all looking quite teneral with pale thoraxes), a lonely very pale/teneral Common Blue and a Broad-bodied Chaser which promptly disappeared before I could get near it. The latter was new to me for Sandhouse.

IMG_9438 Large Red 40D macroI’ve been trying my macro lens mounted on my old 10Mp Canon EOS 40D body, still a very good camera, whilst using my 300mm lens on the 18Mp Canon EOS 7D, my theory being that macro shots rarely require cropping and the 10Mp resolution is perfectly fine. If only my camera rucksack would take both bodies mounted at the same time.  Here’s a Large Red taken on the 40D/Sigma 150 macro combination.

All in all, a very good break from paper-hanging.

Off to a Start at Sandhouse

We landed back in the UK from Spain on Saturday to our traditional welcome of varying forces of rain and wind with temperatures staggering up to the dizzying heights of 12°C. Yuk! Bloody marvelous! Mind you, our trip down to Alicante airport to leave Spain was mostly covered by threatening clouds, though it was considerably warmer. First, we visited Singapore and Cambodia in late February and hoped to return to the beginnings of spring. Failed! Now we’ve been to Spain in late April hoping to return the beginnings of spring and apparently failed again.

Anyway, before Sunday’s rain began, I went to check my favourite local patch, Sandhouse Lane NR, and, after a worryingly quiet start, we spotted about 6 Large Red Damselflies (Pyrrhosoma nymphula), lurking about the main Odo pond. In these temperatures, they were trying not to be very active but they were also tricky little devils to pin down with pixels. We’re back to my favourite “one pair of eyes is not enough” syndrome. Keeping your eyes on your quarry whilst moving ones feet and monopod-mounted camera on a bramble-covered 45 grassy slope is decidedly tricky. Nonetheless, I managed it on a couple of occasions, at least well enough to capture a sample shot of both male and female.

Incidentally, whereas in early spring last year the main pond at Sandhouse Lane was as low as I’ve ever seen it, i.e. completely empty, this year is quite the opposite situation; it is now as full as I’ve ever seen it, a noticeably wider body of water. If the weather will perk up, it should be a nice little habitat again.

We continued into the industrial wasteland of the adjoining old tarmac plant (this was in use while the original section of the M1 motorway was being constructed) where there are several depressions that tend to fill with rain and provide more habitat. Though I was surprised at how little water there was here, we did find some with water and spotted another few Large Reds.

Whilst in Spain, I had received email notification that Bedfordshire’s first Large Red Damselflies this year had been spotted on 1st May. The individuals that we found, 18 in all including a few around neighbouring Jones Pit on a permissive path [clever of them to stick to the permissive path :D], displayed mixed colour maturity, some looking pale and fresh whilst others, like those above, were fully coloured.

Our Spanish hosts, who had returned to England visiting family, told us that England should be in for a good summer “because the crows were nesting high in the trees”. I do hope they are right but, with the current situation, I must confess to misgivings.
