Hi
...post op and my vision has certainly got worse - close up vision is now blurrier than ever before.
I noticed the same thing, but had been to the optometrist some year or so before the operation and had an eye check then (quite a detailed one, several machines, digital images, measurements ...) and so a year after my operation I went back because I couldn't read my laptop as well anymore (which I had been able to read 2 years earlier). They basically said that my degradation of vision was right on the graph for my age group.
After that I told them about the OHS and was wondering about this issue and if it was related. She basically said that it was more likely to be just the timing of the things was the same and I had noticed it more because I was looking for it more.
My own readings into presbyopia have shown 2 interesting things:
1) as you get older your lens (which is a flexible sphere) progressively hardens, this seems to be roughly linear (and based on thousands of samples) within a range and depends on which lattitude you live in. Eventually it reaches a hardness that exceeds the ability of muscles to reshape it.
2) the muscles around your eye responsible for pulling on the lens (to focus) progressively get more pronounced (bigger) as you get into your middle ages. This then seems to reverse.
My personal interpretation on this is as they lens hardens your eye adapts to that until it reaches a point where the ability of the muscle to exert force on the lens is less than is needed to reshape it (and thus focusing).
Now (ahem, my theory) when we have the General Anesthetic the muscles relax for a bit and start to go out of 'fitness', however most of us have reached that point where the ability of the muscles to deform the lens have reached that point of reduced ability. So we end up seeing this as a lack of recovery to where we were before the surgery.
I can't say for sure that is what happens with many, but it seems that's what happend with me and I simply didn't see anything like this in my surgery when I was 28 ... where the only things I saw were those vivid dreams!
and no, lets not talk about the ones this time either!
