wishtobepilot. FAA allows all kinds of eye surgery, to pass all you need is to meet the standards. The FAA also has no Diopter limits, correctable to 20/20 is all you need for commercial operations and correctable to 20/40 for private pilots.
As a point of interest, Currently a debate is brewing among interested parties here to allow private pilots to self certify. That is to fill out a form saying that they are healthy and that is it, no medical exam. Apparently no accidents have been prevented by the current medical standards so why have them?
