Please realize that the article on about.com does not come straight from the AF. I would have the AFI in hand before I think about doing anything. Also, the AF has, in the past, restricted PRK and LASIK waivers to candidates who received the surgery from the AF. I don't know if that has changed, but, I would be 100% sure before I spent my hard earned money at a civilian LASIK drive through clinic that does 20 procedures an hour.
BTW, The AF did my PRK 4 1/2 years ago and I'm still better than 20/15 in both eyes. Very happy with the results and the only cost was I had to be out of the cockpit for 30 days.
