Well I just replied over at the DoDMERB section, but I can also put a couple little bits and pieces here.
Refractive surgery is done at USNA, USMA and USAFA (those are the ones I'm aware of) during a cadet/midshipmen's second class year (junior year). I do not know what the standards are to be eligible for the refractive surgery. I was involved with the initial study group at USNA when PRK was first being offered to a select number of midshipmen, and I can tell you that there were midshipmen who were not aviation qualified at all who were granted waivers (refractive eye surgery was a disqualification at the time) for Student Naval Aviator (pilot). I do not know what the AF requirements are, but I would assume that if, after refractive eye surgery, you met all the vision requirements for pilot, that they would make you eligible for that slot.
The USNA catalog has some erroneous information regarding refractive eye surgery. The current Department of Defense Instruction that DoDMERB uses, states that if an applicant is 6 months status post refractive eye surgery, and his refractive error is stable over those 6 months, it is not a disqualification. Also the applicant’s refractive error must have been within the commissioning limits prior to refractive surgery.
For any applicants who are considering this I will pass my thoughts on the matter. For males - if you are below the age of 20 you are still growing, so if you get refractive eye surgery, your vision will still change and could possible change enough during your 4 years of school that you will not be pilot qualified. For females - you are usually done growing by 18 so this wouldn't be as much of a concern. If you want to get the refractive eye surgery and you have an interest in the military you must get PRK. LASIK is a disqualification, with no waivers ever granted for aviation, diving, special warfare/ops, submarines.
So for the bottom line, I would not recommend refractive eye surgery for any applicants. Wait until your junior year at the academy, and let the government pay for your surgery. This way if there is a complication, the government will fix it at their expense.
