What Is LASIK?

View Video

LASIK (Laser in-Situ Keratomileusis) is a painless procedure to correct nearsightedness, farsightedness and astigmatism by changing the shape of the eye’s surface or cornea.  Depending on the condition, the laser may be used to flatten the cornea, steepen it, or remove irregularities.

During the LASIK procedure, the laser’s cool beam of ultraviolet light removes a small amount of tissue, usually less than the thickness of a human hair. Then, short pulses of laser light change the curvature of the surface of the eye. This allows images to be more sharply focused on the retina, the inner lining of the eye, which is connected by the optic nerve to the brain.

The LASIK procedure is made even more accurate and effective through the use of computer mapping of each patient’s individual eyes. This means that every procedure is custom-tailored to the patient. The goal is to provide residents of Southeast Tennessee, Northern Georgia, and Northeast Alabama with vision improvements that can be truly life-changing.

Dr. DiStefano was the first to offer Intralase, a completely blade-free LASIK, in Chattanooga. Not only does this all-laser method speed up healing time, it is more precise than traditional LASIK using a microkeratome, giving you better results. Read more about Intralase technology.

LASIK surgery changed my life. I'm more productive and more active than ever. I wish I'd done it sooner. Dr. Distefano and her staff were amazing!
