Actually this is a good question. Tough spot if you ask me. If I had to wager a guess, I would say PRK/LASIK is in your future. Brooks is going to do a number of tests on your eyes, and if I remember correctly an auto-refraction test is performed, giving you your BVC (best visual acuity) which I'm going to assume is going to be over -3.00 diopters, which will DQ you.
What happens after this? I'm not sure, someone at Brooks would be the best person to talk to: "What happens if I get DQ'd, can I get LASIK and come back later?" might be a good question to ask. However, you also might be in a bad spot medically when you reapply having to check "Have you ever been disqualified from a commissioning source?" on your brooks application. It will raise a lot of red-flags, and will probably make your second go-around a real headache (even though chances are you'll be WELL within the limits at that point).
Then again, you could go there and they could pass you. The way I read the reg is that your Rx for seeing 20/20 needs to be less than or equal to -3.00 diopters, which if your eye doctor was right, you'd be within.
The good news is that if you DO elect for Refractive Surgery, your chances of a good outcome and subsequent FC1 passing is pretty high.
Honestly, I would CALL Brooks and ask to speak to a flight doc, PM me and I will send you some contact information. They're friendly, and usually very helpful.
Tough spot man, good luck - don't worry, either way you go you'll still be able to push through one way or the other, it just might mean more headaches.
