Advanced Surface Ablation (ASA)
Advanced Surface Ablation is a relatively new laser vision procedure that has addditional safety features over LASIK making it an ideal aternative for some patients. Instead of cutting a flap on the front of the cornea, the surface skin cells (epithelium) are loosened with a diluted alcohol solution and removed. The corneal surface is then treated with the laser and covered with a bandage contact lens.

The margin of safety with ASA may be greater than that with LASIK as the need for a microkeratome is eliminated, so there's no risk of flap complications. You do not need to worry about rubbing your eye or bumping it after surgery and having the LASIK flap slip or wrinkle, because there is no flap. The nerve endings that control tear secretion are not cut, so ther is less of a problem with dry eye after surgery.

ASA removes tissue within the cornea to treat low to high levels of nearsightedness, farsightedness and astigmatism.
