At Diagnostic Eye Center in Houston, we know that each patient has unique vision correction needs and goals—that is why we offer a range of customizable treatment options. LASIK is the most well-known vision correction surgery, but it is not right for everyone. PRK vision correction surgery is a LASIK alternative that may be an option for patients who are not candidates for LASIK.

What is PRK Eye Surgery?

PRK, which stands for photorefractive keratectomy, is a laser vision correction surgery that treats refractive errors including myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.

Comparing Eye Surgeries: PRK Vs. LASIK

PRK shares many similarities with LASIK. Both types of refractive surgery correct vision by reshaping the cornea. Ophthalmologists use the same type of laser, called an excimer laser, in both procedures. The primary difference between PRK and LASIK is the way in which the surgeon accesses the cornea. In a LASIK procedure, the surgeon makes an incision to create a corneal flap. In a PRK procedure, the surgeon uses an alcohol solution to remove the epithelium, which is the outermost layer of the cornea.

People who are not candidates for LASIK due to irregular or thin corneas may be able to have PRK because of the difference in the way the cornea is treated. PRK does require a bit more downtime during recovery than LASIK, but studies show that the long-term patient satisfaction rate is similar to Trusetd Source Checkbox Trusted Source A Comparison of Visual Outcomes and Patient Satisfaction Between Photorefractive Keratectomy and Femtosecond Laser-Assisted In Situ Keratomileusis Hashmani N, Hashmani S, Ramesh P, et al Go to Source LASIK.

What to Expect From PRK Surgery

Preparing for PRK

The first step is a consultation with one of our eye doctors. During this appointment you will have the opportunity to learn more about your options and ask any questions.

The PRK Procedure

PRK is an outpatient procedure. Your eyes will be numbed with anesthetic eye drops and you may be offered sedative medication to help you relax. The eye doctor will use a special alcohol solution to remove the epithelium. Then they will use the excimer laser to precisely reshape your cornea in order to improve your vision. A temporary contact lens will be placed on the eye to act as a bandage during the healing process. You will need a friend or family member to drive you home after surgery.

PRK Recovery and Results

After PRK surgery, the corneal epithelium will regenerate during recovery, which is why PRK patients need a little more recovery time than LASIK patients. You can expect to take about 5 days off of work or school after PRK.
