Concur w/Kilgore. The search will yield alot of great information. I know I have posted links to the Navy and Air Force medical waiver guide sites. These waiver guidelines change as studies are complete and new technologies/procedures become available. You need to do your research before having any medical procedure done in hopes of getting a waiver from a follow on military medical review board. Example: You get PRK/LASIK done with good results. You are denied a waiver because your diopter numbers were outside the limits that the Navy would accept corrective surgery for. End result: NO WAIVER. I have personally seen this happen to a good friend of mine. The Navy didn't tell him about the diopter numbers ahead of time, but it was clearly spelled out in the waiver guide. Again, lots of information is available and it's always changing.
