This is not meant to be a really stupid question.......!
COuld there be an element in there that your brain is having so much to cope with, coping with the foggy sight, the changing sight, etc etc that by the end of a busy day, it just isn't strong enough to suss out what you're seeing, ie. make a "clear" picture despite all the strange eye effects, and you get blurry vision and headaches just cos your brain is getting too tired to work out a better picture any more?
Whatever it is, hope it gets better soon.

You complain about management keeping you off work. I just can't imagine working for anyone who'd let me stay off work for weeks or months (or any time, really) just cos I couldn't get a contact lens in to see fully! I rather expect my past bosses would have expected me to get into work and do the best work I could, however short a time I could get the lens in for, and however little I could see without it. I'd have been expected to get a white stick and/or golden labrador, no doubt!

Thanks again for all the kind comments.

I don't know if you're right, Rosemary, but it's a definate possibility!

I think that management are scared of being sued quite frankly, seeing as how I'm working for an "American" consultancy. I'm not sure all will still be the same when I'm working for Sainsbury's from the end of April.

Well fingers crossed for you John.

Have you considered getting your GP/Consultant to write a letter to your employer explainin that you are able to work albeit at a reduced level?

Paul

[John Smith]

Yes, I'd considered that; they will only listen to their own doctors though.

After a lot of pestering I've finally got an appointment to see them on 31st Jan., so should be back to work soon after I'd think.

your in my thoughts john, hope all works out.

I know what you mean ohn working for American companies.

On the one hand mine is very good in that they do provide the equipment I need despite the trouble with our central ordering system which is another company.

On the other they would like me to work when I can not see, but I work with dangerous chemicals!!!! Besides, public transport what it is would take me 3 hours to get to work and cost f times as much as a car. Average speed to get to work is 12 miles per hour (if calculated as the crow flies, but it is a conveluted route by bus and train), by car it is 48 miles per hour and £5 a day round trip.

Bottom line is, they decided by the time I got in to work I would only be here for a couple of hours which was hardly productive at full efficiency.

Good luck with the appointment.

OK, Just got back from the opticians with new lenses in my glasses

Vision (worn over the left scleral lens) isn't too bad, but I couldn't say yet how much better is is than it was yesterday. It's certainly a lot better than it was without any glasses at all

Asked the optician about the blurryness later in the day, and he suggested that as the odema which causes the morning foggyness dissipates, not only does the fog become less, but the cornea shrinks. He thinks that it could be the continued shrinkage after any perceived fog has gone which is causing the vision change in later afternoon.

Certainly one to bring up with the consultant on Feb 2nd!

Can I jump back to Rosemary's question about the involvement of the brain in perception?

There is a very well documented neurological element in hearing. The first stage in recovering hearing has to do with the mechanics of the ear, the introduction of adequate amplification etc., and then there is a period where the 'hearing' part of the brain re-learns the business of receiving and interpreting signals from the ear.

Far less research has been done in the involvement of the occipital lobe of the brain in the recovery of sight.

It is well known that the brain is capable of putting together a coherent picture of the world from quite fragmentary information transmitted by the eyes. This is why binocular vision is always better (sometimes by a whole line) than the sight of the better eye.

Further, each of us can remember noticing the effect of the brain re-learning to use the signals from the eyes. When we get new specs, the pavement can seem very close, but after an hour or two, the brain has everything sorted out and so the world looks 'normal' again.

For a long time I have been hoping that somebody would undertake some research on the involvement of the brain in putting together a view of the world, post graft. this would be especially interesting if the subjects had suffered from a near complete loss of sight prior to the surgery.

I am absolutely sure that Rosemary is on to something here. Not for the first time she has put her finger on an area of our understanding of perception that needs more work.

What I am saying, John, is that it is very likely that your brain is having a hard time coping with the changes in the signals it is getting: first you needed a graft, then you got one, then you had varying degrees of astigmatism to cope with, now you have varying matches of specs and focus ...

Give it time and it may be that you will be able to sort out from the confusion a clear picture of what is around you. Keep looking for beauty and you will find it.
