(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. 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. 

Dr. DiStefano was the first to offer 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.
