So, you're not in ROTC, and you're planning on trying to get a slot to OTS? You'll take a Flying Class I physical at Wright-Pat AFB in Ohio before you go to OTS; there you'll find out whether or not you're medically qualified by AF standards to be a pilot. You won't go through OTS just to find out you're medically disqualified after you get commissioned. Unless, of course, you break your neck during the 3.5 hours of hardcore, hand-to-hand combatives training you receive.
I can't speak to the Lasik issue.
