For my own case, the prognosis is as good as one might hope for , given my age ; I had two operations today - the first was a straightforward insertion of implant lens ( cataract) which was 20 minutes at the most of mildly unpleasant experience ; the second was because the damaged lens had fragmented and become distributed through the eye , and had to be removed, by a new (?) technique being pioneered I think, at my hospital, involving using ultrasonics to zap the pieces small enough to be hoovered up through the sonics horn inserted in my eye. Remarkably, considering all this happened inside the eye, I could see a lot of it, but it had to be done with me conscious, in order for me to follow instructions, and in terms of pain ( for 90 minutes or so) it is the worst experience of my life, and only the wish to avoid subsequent problems leading to blindness would ever persuade to me to undertake it again , should it, for example, prove necessary with my second eye.
So now I have 4 different kinds of drops to put in, at different intervals over perhaps the next six weeks, and the expectation is that my eyes will be “unbalanced” because the implant in my thrice operated eye now cures my sight enabling me to do most things without glasses – except perhaps reading and close work, whereas the other, untreated eye, needs my usual complex bifocal or varifocal prescription until that too can be done – perhaps later this year. So only a temporary problem.
I’m looking forward to the bandages coming off in a couple of days, and maybe will then get back into the greenhouse !.
