LASIK eye surgery is a visual correction surgery used to change the shape of the cornea (outer covering on the front part of the eye).
Procedure
The LASIK procedure involves using a microtome to cut a thin layer of your cornea while your eye is held open with a spectrum. According to the Food and Drug Administration, a corneal flap is created and pulled back. Laser beams are then aimed at your iris to reshape your cornea. The corneal flap is replaced over your eye and allowed to heal.
Timing
The LASIK procedure takes 10 to 15 minutes for each eye. You will be awake, and a numbing eye drop will be placed in your eyes.
Population
According to Medline Plus, LASIK surgery is performed mostly on people who have nearsightedness. But this surgery can be performed on people with farsightedness and astigmatism.
Risks
According to the FDA, LASIK eye surgery contains many risks. You can lose your vision or get an eye infection. Your eyes might lack enough tears and remain dry. You might have double vision or see halos.
Prognosis
According to Medline Plus, it takes about three to six months for your vision to fully improve. A second surgery might be necessary for maximal results.
