I had LASIK surgery in '94 it was still fairly new then went from -12 & -14 to 20/20 & still 20/20 today, reading is fine in normal light, but if its dim light then I could use reading glasses but usually get more light on the topic which works fine. Very happy with my results I had a few issues with CAA then now CASA changing my medical status & clearing me to fly, I was grounded about 6 months but since then everything is great. I think the skills of the Doctor have the most to do with your results.
