Laser Epithelial Keratomileusis – LASEK is a variation of both the PRK and LASIK laser eye surgeries. The surgeon loosened the the outer layer of the cornea known as the epithelium with an alcohol solution during the procedure. The thin layer is then pushed aside. The cornea of the patient is reshaped with the laser for vision correction in the same way as standard LASIK and PRK. The outer epithelial layer is now replaced with a contact lens.
Until the surface layer is reattaches and heal itself, the contact lens is left in position in the eye. There are few drawbacks to LASEK procedure as well, which may include discomfort following the procedure and increased healing time in comparison to LASIK procedure in some cases.
