P-R-K works, it's like lasik BUT instead of pulling up your cornea, lasering your lens, and putting your cornea back down, ..... the doctor will use a "buffer" like what a dentist would to polish your teeth to BUFF OFF YOUR CORNEA, laser your lens, and then you wear goggles and/or sunglasses for a couple months until you're healed. it fixes astigmatisms and is more thorough all around, but it's rediculously painful before and after, you have to watch as someone buffs your eyes, and if you don't cover your eyes correctly for two months your vision will be affected. if you don't have major eye problems lasik will probably work.
