What is Advanced Surface Ablation (ASA)?
Advanced Surface Ablation, in its current state, is a relatively new laser vision procedure that has additional safety features over LASIK making it an ideal alternative for some patients. Instead of cutting a flap on the front of the cornea, the surface skin cells (epithelium) are removed. The corneal surface is then treated with the laser and covered with a bandage contact lens, unitl the surface has healed.
