LASEK stands for Laser Assisted Epithelial Keratomileusis. It can be used to correct short-sightedness, long-sightedness and astigmatism. LASEK eye surgery is an alternative procedure to LASIK. LASEK is a modified version of PRK (Photo Refractive Keratectomy), a previous type of laser eye surgery which is less commonly performed these days.
The LASEK procedure involves removing the top layer of the cornea as a flap-like sheet before re-sculpting it with an excimer laser. The epithelial sheet is then replaced on the surface of the eye and a soft contact lens is then inserted for a few days following the surgery.
Patients who have undergone LASEK surgery see an immediate improvement in the clarity of their vision, and the recovery time is relatively quick.
