Why has advanced surface treatment (AST) or Superficial Epi-Laser nearly replaced LASIK in our practice at the Shealy Eye Laser Center?
• Answer: Improved equipment, better pharmaceutical treatment, and increased concern over LASIK complications have greatly improved staff and patient satisfaction. Our center has found that the risk for kerectasia has decreased dramatically, especially in patents with no preoperative warning signs. Lifting the LASIK flap for enhancement has, in the past, increased epithelial ingrowth and scarring of the cornea. The rate of epithelial ingrowth has decreased from about 10% to none.
