Here's the regulation (Air Force Instruction 48-123): http://www.e-publishing.af.mil/share.../AFI48-123.pdf

I'm not a doctor, I'm not that familiar with medical waivers... but I've been in the USAF long enough to get plenty of waivers to plenty of other regulations. The process is all about the same.

Your best bet - research the AFI, find out exactly what paragraph needs a waiver, find out who is the approval authority. Chapter 6 has all the flying information, including waiver process.
