How LASIK Works
Cool rays of light from the Excimer Laser reshapes the inner tissue of the cornea with up to .25 microns of accuracy. In order for light to focus more clearly on the retina the outer window of the eye and the cornea must be of the proper curvature.
After your eye has been numbed with "eye drop" anesthesia an eyelid speculum will be positioned to hold your eyelids open. The microkeratome is used to create a protective flap that is folded back.
Cool rays of light from the Excimer Laser then reshape the inner tissue of the cornea with up to .25 microns of accuracy. Often only 50 microns of tissue (about the thickness of a human hair) are removed to achieve the proper amount of correction.
The corneal flap is then folded back into place and the eye is allowed to heal naturally without the need for stitches. Most patients enjoy dramatically improved vision within hours of their procedure.
