LASEK - Laser assisted subepithelial keratectomy


Laser-assisted subepithelial keratectomy (LASEK) is a laser surgical procedure for the correction of refractive error. LASEK is specifically used to correct astigmatism, hyperopia (farsightedness), and myopia (nearsightedness). It is a “hybrid” technique between laser assisted in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK).

The LASEK technique, like PRK, is specifically helpful in patients with corneas that are otherwise too thin for LASIK.

By retaining a flap of corneal epithelium, LASEK may decrease the risk of infection and incidence of corneal haze, while reducing recovery time and postoperative discomfort when compared with PRK.


LASIK and LASEK share some things in common and have certain differences. The goal of both surgeries is to change the shape and power of the front part of the eye called the cornea, which is the clear window of tissue overlying the colored iris and pupil, such that light travels through the cornea and then the lens, and will then be focused on the retina, achieving clear vision.

LASIK and LASEK procedures both involve the use of an excimer laser. This cool beam, computer driven, ultraviolet laser changes the shape of the cornea by a chemical process known as photoablation. In LASIK, a corneal flap is created followed by application of the laser. In LASEK, only the outermost layer of the cornea is removed or loosened using a special solution. It is then brushed away followed by the application of the laser, and then in some patients, the outer layer may be repositioned, and in others it may be discarded, but in both conditions the outer layer will rejuvenate and replace itself in three to five days.

Visual recovery is faster in LASIK than LASEK; however the end result is very similar and the differences are so minor they are not considered significant. The decision on which procedure may be better for you will be made following a detailed examination of your eyes, including measurements of your corneal thickness.

If you have a thin cornea or a particularly dry eye, or participate in contact sports, it’s possible that the ophthalmologist may recommend LASEK versus LASIK. In other cases, LASIK may be recommended because of the faster visual recovery.
