Hello -- I'm glad that my posts helped someone -- you! I do still see the crescent of light near the bottom of my field of vision for my right eye which had the iridotomy at about the 12 o'clock position. I don't think I notice it as much anymore. And I only notice it under certain lighting conditions. Bright sunlight is the worst -- and especially when driving. I find that wearing sunglasses helps immensely. I was never one to wear sunglasses much but I sure do now. My left eye was the temporal position. I have very little difficulty with any light abberration in that eye. Once in a great while, if the light is very bright and at an odd angle, I will see a little bit on the lateral side of my vision which is vertical. I wish that I had done extensive homework before I had my right eye done --- but I didn't anticipate trouble, nor did my ophthalmologist. Had I known that I would get a dysphotopsia -- I would definitely have requested the temporal position for both eyes. I hope that with some time -- maybe up to even a couple of years --- that this light streak in your visual field will lessen.
