Lasek, or Lasik, is a type of PRK surgery to correct myopia, camera, and astigmatism. Lasik eye action is a special combination of Lasik eye action and PRK action. LASIK is actually a type of corneal surgery that removes refractive errors in your eyes. Lasik is the most popular laser eye surgery, but for people who do not have LASIK conditions, PRK or Lasik is an option with better results compared to LASIK. Like other types of laser refractive surgery, LASIK also works by deforming the cornea using an eximer laser, allowing light to reach inside the eye, so that your visual clarity is optimal without wearing glasses or lenses.
