I just wanted to clarify some of the information on this thread. USAFA performs both LASIK and PRK, however, if you want a rated AFSC such as a pilot, you can only get PRK. The acceptable range of correction to be approved for surgery is minus 3.25 to minus 8.0.
Some cadets are in a what is called the "Cadet Warfighter Program" where they can get evaluated by the surgeons and approved for either LASIK or PRK, at no cost. These cadets are the ones pursuing non-rated AFSCs.
The process for getting approved for surgery is very long and involved. Our son has been being evaluated and tested pretty much since he got to the Academy. This last year he had to have three different periods of not wearing his contacts for 30 days, and had a regimen of eye drops and artificial tears to follow every day. Last week he finally got his official approval and will have PRK in August, right after the wing returns to the hill. The Academy won't perform the surgery until the cadet has started their 3rd year and have committed.
