Our corneal specialists at the Cizik Eye Clinic perform refractive surgery, a general term for procedures that correct visual perception or focus to reduce or eliminate the need for glasses or contacts, with the objective of reducing or eliminating the need for glasses and contact lenses. Recovery from these types of surgeries is typically fast with little discomfort. Mild pain medicine and eye drops can help with any dry eyes or pain following surgery.
These procedures include:
LASIK is an outpatient surgery procedure that corrects nearsightedness, farsightedness, and astigmatism. A laser is used to reshape the cornea — the clear, round dome at the front of the eye — to improve the way the eye focuses light rays onto the retina at the back of the eye. The ophthalmologist creates a thin flap in the cornea using either a blade or laser. The surgeon folds back the flap and removes corneal tissue under the flap with a laser. The flap is then laid back into its original position to heal.
For nearsighted patients, LASIK is used to flatten a cornea that is too steep. For farsighted patients, LASIK is used to make the cornea steeper. LASIK can also correct astigmatism by reshaping an irregular cornea.
LASEK eye surgery is used to correct astigmatism; myopia, or nearsightedness; and hyperopia or farsightedness. Like other types of laser refractive surgery, LASEK works by reshaping the cornea with an excimer laser, allowing light entering the eye to be properly focus on the retina for clearer vision. The corneal epithelium is separated from the underlying stromal layer, and the surgeon pushes the ultra-thin epithelial “flap” to the side, exposing the corneal stroma for laser reshaping.
LASEK avoids the complications that come with creating and reattaching the flap in the cornea. Patients also report fewer cases of dry eyes following LASEK, as compared to LASIK. It tends to take a little longer to recover visually after LASEK.
Photorefractive keratectomy, or PRK, is a type of laser eye surgery developed before LASIK to correct mild to moderate nearsightedness, farsightedness, and/or astigmatism. All laser vision correction surgeries work by reshaping the cornea, or clear front part of the eye, so that light traveling through it is properly focused onto the retina located in the back of the eye. During PRK, a laser, which delivers a cool pulsing beam of ultraviolet light, is used to reshape the cornea. The thin outer layer of the cornea is removed and is not reused to reshape the cornea. Instead, it will naturally grow back a few days after the surgery. PRK does have a longer recovery time because the outer layer of the cornea needs to grow back to cover the eye’s surface.
