Well, I want LASIK too, but it is damn scary! Watch it on YouTube(Don't wanna put you off, watch at own risk)
As Brother Faisal(DR.Faisal) mentioned above, the have to cut a slit in the cornea, lift it up and perform the laser treatment, that is the tricky part, since they leave a tiny bit attached, and sometimes the whole flap comes off. Ask for Z-LASIK, they don't usually cut a flap, so that should be more safer!
Good luck and keep Us updated, I am really interested.
BTW: I wear contact lenses, L: -5.00 R:-5.25.
