LASIK (Laser-Assisted in Situ Keratomileusis), commonly referred to as laser eye surgery, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism.
During LASIK, a thin corneal flap is raised (less than 150 microns) and the shape of cornea is modulated with laser beam after which the corneal flap is replaced. The total procedure time on each eye is 5-7 minutes. During the procedure the patients lies down on an automated resting couch which aligns the patient with the LASIK machine. Topical anesthetic drops are applied and the patient is asked to look straight, not to move the eyes and be completely relaxed. The surgeon always help the patient by communicating to him/her.
