You're half right. There're three types, as you say; LASIK, LASEK, and PRK.
Two of them; LASEK and LASIK (laser epithelial keratomileusis and laser in-situ keratomileusis) involve creating a corneal "flap" which is lifted. The eye underneath is reshaped by laser, then "natural suction" holds the flap in place as it heals. LASEK preserves more of the cornea so healing is shorter.
PRK (photorefractive keratectomy) involves ablating the surface of the cornea, so nothing is cut; the surface it worn down to a different shape, affecting vision in the desired way.
Anyway, they've decided that LASIK and LASEK are unsuitable because there's a risk of the cornal flap detaching under G or the forces experienced during ejection. Also, one of the types affects night vision, with point sources become a little flared; you'd be no use for night flying.
PRK has been ruled as safe for pilots.
However, in the same way that current aircrew can wear contact lenses and glasses, it's
ONLY CURRENT AIRCREW can serve after this surgery.
You
cannot have the surgery then join; in the same way you can't have glasses when you apply. If you're brave enough to go for a consultation with an RAF opthalmologist then take up to a year of flying after, a pilot currently serving can have PRK.
However, it's always a risk, and it's made clear that if I were to do it and damage my eyesight; tough.
I should imagine that you will always require natural perfect vision to join as a pilot; there's no need to let people in who need glasses or surgical correction.

Never, ever, ever make decisions about an application based on things people tell you on this forum or others. I may have a bit of paper sitting here telling me you need +/-3.00 vision, but there's
no guarantee it's in date, it's correct, that your eyes are as you think, or even that someone here is telling the truth. Although I am
This forum is an excellent repository for advice and information, but regarding anything medical it's always best to:
1. Tell the truth on your form completely and utterly to the best of your ability.
2. Go to OASC and let
them make the decisions on your medical fitness.
Don't leave an application untested because someone tells you they think you're out of medical limits.
