What is PRK?

PRK, or photorefractive keratectomy, is a laser eye surgery procedure similar to LASIK except that the laser works on the surface (just under the epithelium) of your cornea instead of under the flap.

What vision problems can PRK fix?

PRK is most commonly used to treat farsightedness, nearsightedness, and astigmatism.

How does PRK work?

Using the most advanced laser eye surgery technology, Dr. Abel reshapes the surface of your cornea to improve your eye’s ability to focus light onto your retina.

What’s the difference between LASIK and PRK?

Both PRK and LASIK are performed with an excimer laser, which uses cool ultraviolet light to gently reshape your cornea. The biggest difference is during the LASIK procedure Dr. Abel creates a thin corneal flap and the laser ablates the corneal tissue under the flap. Dr. Abel then replaces the flap, which acts as a natural bandage for the cornea allowing for a speeding recovery. With PRK Dr. Abel removes the corneal epithelium (which will regenerate over a 3-4 day period), then uses the laser to reshape the surface of the cornea. Since the epithelium is removed it takes longer for the eye to heal after PRK and may involve slightly more discomfort. PRK is generally preferred in, but not limited to, patients with thin corneas, slightly abnormally shaped corneas and patients with dry eyes. PRK has the potential to provide results equal to and sometimes better than LASIK.

Is PRK painful?

A mild sedative and topical anesthetic will be administered before the procedure so most patients only experience a slight pressure on the eye during the procedure. After the procedure, Dr. Abel will prescribe medicines to help you manage any discomfort you may experience during the healing process.

What are the benefits of PRK?

The biggest benefit is an improved quality of life.

What are the risks of PRK?

The most common complications include under or over-correction, night glare, haloes, light sensitivity and dryness. However, the advanced laser eye surgery technology Dr. Abel uses for PRK significantly reduces these risks. Dr. Abel and his staff will go over all of the risks and potential complications with you in detail during your free consultation.
