Good job on spotting that samadma. You are correct, and just to add to the gouge here from the info I've recieved from my OSO, I'll pass it on.
For PRK, you need to have full medical documentation of your eyes pre-surgery, why you'd make/not make a good candidate for the surgery, post-surgery, as well as a 3 month post-op checkup. This goes against what I've heard for the post-op, that being that it was 6 months, but my info states a 3-month check up.
For the contact lens waiver, you again need full documentation pre-contacts, uncorrected, then documentation of use of a list of pre-approved models of contacts. There's a good amount of contacts approved under each brand, so be sure to get that list and look it over to see if your current contacts match it. Then, you'll need a 6 month post-"op" eye exam to approve that the contacts are working sufficiently with your eyes and that your eyes have had no drastic changes since wearing them.
Again, this is all the info I've received in a direct packet from my OSO as of December 2005. This information could change, and it might not. If you'd like to say, "No, you're wrong, THIS is how it is." feel free to do so, but know that this was the information supplied to me from my OSO. But as always, your best bet is to just talk to your OSO and see what the grade A beef is.
As for me, I've badly wanted to get rid of contacts for as long as I can remember. So whether or not I go air, I'd like to have eye surgery anyway, if I meet the requirements for it. The money is not a huge issue, as I'll have a steady 2nd LT's pay coming up soon enough! Heh, but until then, that's what nice little low interest student loans and financing is for. Also, most places I've talked to will offer some type of discount seeing as how it's military related.
