I myself have done a lot of research on the PRK program. There really aren't that many secrets to it. In fact I've been able to talk openly with the folks in charge of the 10th AMDS at USAFA. Basically, your eyes have to be pretty healthy and fit within certain vision parameters (-3.25 to -8.00 diaopters to be exact) for them to offer you a chance to go through the PRK program. Remember, it's offered, you don't ask for it. After you're selected for the program it isn't always a breeze for everyone. About 10% will wash out due to corneal issues or an unstable prescription. Then, just like any other pilot, you need to have good color vision and good depth perception. So, is it possible? Yes. If you get selected for the PRK program, you have a pretty good chance of making it through. Many cadets have already received the surgery. But you need to ask yourself: If I don't get PRK surgery, will I still want to attend the academy? It's vital you ponder over this and your reasons for attending. Hope this helps.
