PRK factoids
In general, a designated aviator who wishes to get PRk done, goes to a military eye clinic and gets screened by the eye doctor (optometrist). If you meet the requirements (must have vision worse than 20/30, astigmatism from 0.25 to 4.0 D), they give you a PRK consult to see the eye surgeons (ophthalmologists). This consult has to be approved by your CO, optometrist, and flight surgeon. In the past all class I aviators had to have their consults sent to San Diego and have their surgery done at a Navy hospital, but Class II and III's could get it done at any DOD facility. Now I think that has changed, so all designated aviators can have it done at any DOD facility, so long as the request is first submitted to the NMC San Diego Refractive Surgery Center, then to the DOD eye center of your choosing.
Current NAMI gouge is that having PRK done at a civillian facility PERMANENTLY grounds you (for poor headwork at the very least) Also of note is that Class III bubbas (the air traffic controllers and UAV dudes) are the only ones who can have LASIK done.
I have zero knowledge of the who/how/when's etc at Tinker. However, if I were have any operation performed on myself or someone I loved, I would want it done at a center that does a tons of them on a regular basis, vice the one that fit my schedule best. Especially something done on my eyes, of which I don't have a spare...
