Well it's definitely worth your time researching if you meet the NFO requirements. The requirements for your eyes are quite a bit different for NFO and pilot, so if you're borderline for pilot, you're probably ok for NFO. Emphasis on probably.
There are risks associated with getting PRK in order to get a pilot slot. It may not get you where you need, or you might get it and still not get picked up. However, I know many people, myself included, who have had PRK and had overwhelmingly positive experiences with it. I would not have been qualified for SNA without it. That's not intended to steer you either way, just some more amplifying info. Good luck.
