Why do 'gnats' appear in the eyes? This may be a sign of increased or low blood pressure, avitaminosis, cerebral blood flow disorders, etc. This may be the first bell of an impending disease. If the flickering in the eyes disturbs you often, you should sound the alarm. If this happens rarely, there is no reason to call a doctor. But it would be very excellent if it did in fact disappear altogether, and I liver in hope.There is no such person, who at least once in his lifethere was no flickering in the eyes. I suspect it is a brain function problem I am coping much better with it- bright sunshine still a problem, as is the feeling that I am looking through a keyhole, but wearing any spectacles helps - just by having a frame there seems to lull the brain into accepting the dark edge. He said he had no patients returning to complain of the problem after 6 months- as if to reassure me that mine too would be gone by then, but if i do still have the problem, I shall not return to him either, since I realise there is nothing more than can be done, surgically. My consultant commented that I was 'one of his exceptional patients'- a disingenuous attempt to enhance the situation. There is indeed little on the net from consultants in the field, although I did find an article that indicated that specific lens size, edge & material contributed to the problem- viz: 6mm or less, square edge, acrylic rather than silicone. Having experience the battery-hen environment he has worked in so far, I doubt he will bother to spend any time on an explanation, even if he has one. I'll be interested to see if he comes up with a plausibe explanation. I'll tackle him about this apparently common side effect in a few weeks when I next see him. However, it was very noticeable in bright sunlight immediately after visiting my opthalmologist and having the dressing removed. Nevertheless, I am very happy with my much-improved vision, and the flickering problem does seem to be receeding somewhat. It could be a purely brain-related phenomenom, rather than physical cause, I have yet to read a convicning explanation. I would seem that the experts really don't have a convincing explanation, and they tend to dismiss the problem rather than attempt to explain it. There seems to be a lot of discussion on the Web about this condition - stemming from patients rather than opthalmologists. Yes, I had left-eye cataract surgery here in Canberra just 4 days ago, and I have since experienced pretty much the flickering vision that Rady describes. I hope as others have said that time is a great healer and that it eventually disappears on its own, as it is driving me nuts at present, perhaps using sunglasses with a side cover on might help me, well its something I'm going to try. I had a cataract operation and Implant in my right eye done about 7 years ago and cannot recollect having these flickering problems then ? my optician said its possible that the light reflection is coming from the implanted lens and radiating around, she said my eye needs time to settle. In bright light I to have this flickering which comes from the left side of my periferal vision and then spreads from left to right and yes its very annoying, as I type this comment I'm having to shield the light with my left hand against the side of my face to somewhat stop the side dazzle it doesnt however stop the flicker when I move my eye left to right, when I'm looking straight forward I dont get the flicker. I'm recovering from cataract Implant surgery in my left eye, It''s been nearly a month since my surgery, I've found in the early morning that the light in the partial darkness of the bedroom is not an issue with my eye, but as some of you have already talked about bright light then I have to agree with you all.
