what is lasik
Dec. 12, 2015. LASIK (laser-assisted in situ keratomileusis) is an outpatient refractive surgery procedure used to treat nearsightedness, farsightedness and astigmatism. A laser is used to reshape the cornea â the clear, round dome at the front of the eye â to improve the way the eye focuses light rays onto the retina at the back of the eye. With LASIK, an ophthalmologist creates a thin flap in the cornea using either a blade or a laser.
LASIK, or laser-assisted in situ keratomileusis, is the most commonly performed laser eye surgery to treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. Like other types of refractive surgery, the LASIK procedure reshapes the cornea to enable light entering the eye to be properly focused onto the retina for clearer vision. In most cases, laser eye surgery is pain-free and completed within 15 minutes for both eyes.
