PRK is generally the only accepted method, and you must still meet certain technical ctiterial (spherical error limits, etc).

LASIK has not generally been allowed, and never for off the street hires. The concern has always been that the corneal flap (which apparently never fully heals) could be knocked loose in an ejection or due to proximity to a blast overpressure.

There have been a few recent experiments with LASIK, but only for those personnel who are already in the military, already in a flight status (or service academy cadets), and who have been specifically screened and approved. The purpose of these experiments is to determine if LASIK is safe for pilots in the long run.

As fas as I know you are currently disqualified for flight status, but pending the outcome of their experiments they might grant blanket approval for LASIK for all comers in the near future.

But info on the internet might be outdated...you need to get the straight scoop from the USAF. Different services may (probably) have different rules but ANG should be the same as USAF. For all I know they issued blanket LASIK approval last Friday.

The folks at baseops.net might know more about this.
