LASIK Explained

LASIK corrects optical imperfections including nearsightedness, astigmatism and farsightedness. It’s quick, virtually painless, and results can be observed immediately. The vast majority of people return to full activities the very next day. LASIK works by changing the curvature of the front corneal surface using computer-guided laser systems. To fully understand how LASIK works, it helps to first understand how the eye works.

How the Eye Works

The eye works like an elegant biological camera. Light from the outside world is focused by the combined effect of the cornea and the lens, so that a sharp image is created on the retina. In an eye with no need for distance prescription, light is brought into sharp focus exactly on the retina.  The optically optimal eye of a person with zero prescription can see clearly at all ranges, near and far. Nearsightedness (myopia), farsightedness (hyperopia) and astigmatism are all imperfections of distance vision.

How LASIK Works

LASIK takes the imperfect shape of your cornea, whether too steep, too flat or out of round, and brings it back into round.  This technology has elegantly resculpted the vision of literally millions of patients worldwide over the last 25 years.  It takes a lifetime of blurry vision, and sharpens it in literally seconds.
