I had RK surgery in 1991 (this was when they cut your eyes, before laser surgery) which gave me 20/20 vision. The Optho/Neuro can't see past those cuts, and when I did finally find him, the flair had passed, so I've yet to be dx'ed with ON. I have residual effects tho that have never left

There goes my dinner bell

Talk to you later!
