Lasik eye surgery – Risks?
LASIK eye surgery is the best known and most commonly performed laser refractive surgery to correct vision problems. Laser in situ keratomileusis (LASIK) can be an alternative to glasses or contact lenses.
During LASIK eye surgery, a special type of cutting laser is used to precisely reshape the cornea (the clear, dome-shaped tissue at the front of the eye) to improve vision.
Under normal conditions, the cornea deflects (refracts) light correctly onto the surface of the retina at the back of the eye. But in cases of nearsightedness, farsightedness or astigmatism, the cornea refracts light incorrectly, causing blurred vision.
Glasses and contact lenses can correct vision, but reshaping the cornea also allows the necessary refraction to occur.
