Yogagran I know what you mean about risking sight. My daughter had laser surgery to correct her short-sightedness and I was wary about it. Soon after I had to have cataract surgery - not much choice there. I too have told about my experience on the Cataracts thread. Of course it's a different procedure, but about 18months after my surgery, I had a couple of very minor problems which were sorted out in minutes by laser surgery. It can hardly be called surgery really. Think of what happens when you are having your peripheral vision tested in a routine test. (That's when you see dots appearing somewhere on the screen and you have to press a button when you see the dot.) Now imagine that with red dots, fewer of them and no button to press. It's non-invasive and painless and has no after-effects apart from avoiding bright light for a couple of hours. I wouldn't dare to tell you to do it, but please be reassured enough to perhaps investigate further.
