There are over half a dozen Lasik related procedures today. It all depends on what machine your doctor does it, and what is your eye condition. It can be Lasik, Lasek
, Epilasik, Wavefront guided or Topoguided surface procedure etc. The best for your kind of power is to get Wavefront as well as Pentacam analysis of your HOA, and if they are significant, get an advanced surface procedure, correcting not only your spheres, cyls as well as coma
and HOA. Dont go by the advertisement, which are always given with a vested interest.
