LASIK, or “laser-assisted in situ keratomileusis,” is the most commonly-performed laser eye surgery to treat myopia (nearsightedness), hyperopia (farsightedness), and astigmatism (spherical curvature of the eye/lens).
LASIK 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. The results — improved vision without eyeglasses or contact lenses — can usually be seen in as little as 24 hours.
LASIK is not advisable for everyone. Your doctor will carefully evaluate you to see if LASIK is right for you. If you are not a candidate, other laser surgery alternatives,
such as epi-LASEK, may be available.
