I don't have a link for it. This is just what my flt doc told me the other day. I had asked about PRK and was planning on getting it when i left my current command (they wouldn't approve it if I were to be down for so long).
There is no difference in how the laser fixes your eye, that I know of. The main concern for Lasik, according to my doc, was that the flap of skin could blow open during ejection. After tests it was shown that this wouldn't happen, even with 800mph blasts of wind. I won't go into detail on what the doc told me about how the tests were conducted.
I only have the info the doc gave me. Lasik sounds fine for me and the recovery time will get me flying again much faster. I don't fly ejection seat aircraft, so that little flap of skin isn't much of a concern to me. If Lasik is approved, as it appears it will be, then i expect the navy to completely move to it because of the faster recovery time.
