This was already discussed to some extent here, though it was some years ago...
I am still putting my application together for SNA/SNFO. I am scheduled to take the ASTB July 8 and going to MEPS some time after that.
The only way I can see myself being medically DQ'd is for vision. I have worn contacts for about a year and half now and am quite certain that my vision without them is not 20/40. I do not know exactly what it is at this time.
Main questions for someone who would know or has experienced this:
Is there currently a SNA contact lens waiver? Can you be waivered for PRK/Lasik (correct to 20/20) if your uncorrected vision is worse than 20/40?
I have read a couple of the (current?) Aeromedical guides, but it can be hard to decipher what rules apply to whom and which ones have changed recently.
Also... supposing all this was to work out in my favor, but I had to get surgery, I assume the surgery would be done (at my expense) prior to OCS? I ask because my OR said that if I pass at MEPS for 20/40 (which I doubt) I can wait until after API, Primary, Advanced etc... and get the surgery done at the military's expense. That does not sound very reasonable to me nor would it be something I am comfortable with if I am not allowed to wear my contacts. I am not blind, but I would not want to fly anything without better vision than I have sans contacts.
This all assumes that I would not be DQ'd at NAMI after OCS. Seems like that is where the crap generally hits the fan.
