What is Laser Eye Surgery?

Laser eye surgery is an umbrella term for several eye surgeries used to correct refractive errors. The most common types of laser eye surgery include LASIK, PRK, LASEK and EpiLASIK.

Each of the four laser eye surgery procedures below use the same special laser, called an excimer laser, to reshape the cornea. This is what corrects vision. But laser eye surgery can vary in the specifics of the procedure, the recovery time, which surgical instruments are used and your patient candidacy. You might be a better candidate for PRK, for instance, than for LASIK.

The Right Laser Eye Surgery

In Location, Dr. Name is able to determine from a comprehensive, laser-eye-surgery-specific eye exam which procedure is best for you. The doctor’s recommendation will follow which procedure they think will give you the best possible outcome. Most patients achieve 20/20 or better vision after laser eye surgery.

  1. LASIK: Laser in Situ Keratomileusis

LASIK is the most common laser eye surgery. LASIK starts with the creation of a thin flap in the cornea. Once the flap is created, the excimer laser is used to reshape the cornea which corrects the refractive error.

  1. PRK: Photorefractive Keratectomy

PRK is the second most common type of laser eye surgery. PRK starts with the removal of a portion of the surface of the cornea or epithelial tissue. There is, therefore, no need for flap creation and the removed tissue grows back. Some patients prefer PRK because they don’t want a corneal flap, and some patients are better candidates for PRK eye surgery than for LASIK (for instance, people with thin corneas). Once the epithelium is removed, a laser is used to reshape the cornea. The PRK recovery period is a bit longer than that of LASIK.

  1. LASEK: Laser Epithelial Keratomileusis

LASEK is similar to LASIK and PRK, but it starts with the application of alcohol to the corneal epithelium. This loosens the outermost corneal cells and allows the surgeon to move them out of the way, without removing them, for the laser procedure. After reshaping the stroma with the excimer laser, the surgeon can replace the sheet of epithelial cells and put a contact lens in to let it heal. LASEK can be a good option for patients with thin corneas.

  1. Epi-LASIK: Epithelial Laser in Situ Keratomileusis

Epi-LASIK starts the way LASIK does, except the flap is thinner and made only of epithelial tissue. Once the flap is created it is moved aside just enough so that the surgeon can reshape the stroma underneath with the excimer laser. The flap of epithelium is then replaced and covered with a contact-lens bandage to heal. Some consider Epi-LASIK a hybrid of LASIK and LASEK. Some surgeons believe Epi-LASIK is a good option because the flap exists only in the epithelium layer and because there’s no alcohol used during the procedure.
