I had PRK in '05. Was 20/15 after the surgery. Now I am 20/30 and fly with glasses. Thinking about it now, the procedure freaks me out. But it allowed me to fly for the AF (would have otherwise been DQ'd), so it worked out. Be sure to take care of your eyes post-op and use the drops. My vision at night is a little different, but it passes all the AF tests.
