is a means of correcting vision by treating beneath the surface of the cornea using a laser. It is currently the most technologically advanced surgical procedure for correcting myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. LASIK has helped millions of people across the world reduce or even eliminate their need for glasses and contact lenses.
At the Shenandoah LASIK and Cataract Center we use a . The excimer laser produces a beam of cool ultraviolet light. The doctor programs your information into a computer that controls the laser. The computer creates an exact treatment plan based upon your individual eye ultilizing VISX CustomVue Technology. The laser produces a series of pulses that remove small and precise amounts of corneal tissue. Excimer laser light does not penetrate into the eye and leaves other eye structures (iris, lens, retina) undisturbed.

The laser also contains an auto-centering eye tracking system (shown above which will automatically compensate for any of your eye movements during the treatment.

Introduced in 2000 by the inventor of LASIK, Epi-LASIK combines the best features of LASIK and PRK while reducing complications such as haze and halos, dry eye, loss of nerve sensitivity, post-operative pain, vision regression and continued need for eyewear. Like PRK, Epi-LASIK affects only the surface of the cornea. Like LASIK, it involves making a flap of corneal tissue to reduce pain.
During Epi-LASIK a blunt microkeratome smoothly separates the surface layer, or epithelium, from the cornea. This thin flap is what gives the procedure its name: "Epi" stands for the Greek word "Epipolis," meaning "superficial." This avoids complications associated with the deep stromal flaps of ordinary LASIK including flap irregularity, epithelial ingrowth and corneal ectasia. Also, using a microkeratome to create the flap preserves cell integrity better than the alcohol solution used in the LASEK procedure.
Next, a laser reshapes the surface of the cornea to improve vision. The epithelial flap is then replaced and covered with a protective contact lens. The flap heals in a few days with very little pain and without stitches.
