Laser Assisted Sub-Epithelial Keratomileusis (LASEK) is a refractive surgery technique developed by Italian doctor, Massimo Camellin, MD and first publicized in 1999. The motivation behind LASEK was to find a surface ablation technique like PRK that induced less discomfort, offers a lower incidence of corneal haze, and provides the patient with faster vision recovery time.
The concern between LASEK and LASIK is the Lasik flap. Although it provides the patient with more comfort, virtually eliminates the probability of haze, and offers very quick visual recovery, if the flap exists, there will be the possibility of flap related problems. Those potential problems do not stop when you leave the surgery suite. Once you have had Lasik you have always had Lasik and you must always consider that your eye is fundamentally and forever changed.
