Why PRK Instead of LASIK?

Dr. Cohen will go over all your refractive surgery options during your initial consultation. PRK is generally recommended for:

Patients with Thin Corneas

Although both LASIK and PRK achieve the same vision-improving results, Dr. Cohen's patients with thinner corneas may not be good candidates for LASIK. Here's why:

LASIK requires a closable flap to be made in the top layer of the cornea so the excimer laser can reshape the eye tissue below. A thin cornea may make creating this flap difficult. PRK does not require a corneal flap. For this reason, PRK can be an effective alternative for patients who are not eligible for LASIK eye surgery.

Patients with Active Lifestyles

Certain hobbies, such as boxing and surfing, can put you at higher risk of injuring the eye. Patients with active lifestyles who choose LASIK have an increased risk of the flap becoming dislodged and other complications. For these patients, PRK is typically a safer choice. Members of the military and similar occupations might also decide PRK is a better fit for this reason.

A Look at the Procedure

In cases of nearsightedness or farsightedness, Dr. Cohen will reshape the cornea using our laser to improve your vision. For astigmatic patients, the curve of your cornea is sculpted into a more regular shape, reducing or eliminating blurriness and double vision.  

The PRK Timeline

You will first have a thorough eye exam with Dr. Cohen to discuss if PRK or LASIK will be best for your vision needs. Your overall health and medical history will be evaluated as well. Pregnant or nursing patients should delay the surgery until Dr. Cohen deems it safe. The PRK procedure follows several simple steps:
PRK can be completed in about 15 minutes.
PRK can be completed in about 15 minutes.
Topical anesthetic drops will be applied to your eyes. You should feel no discomfort after that.
Next, the doctor will use our excimer laser to remove the epithelial, or surface layer of corneal cells. Based on precise measurements taken at an earlier exam, he will then reshape the cornea.
After about 15 minutes, the surgery will be done and you can go home to rest. Please have someone drive you to and from your appointment.

Recovery Time

PRK patients will have blurry vision for about a week until the top corneal layer grows back. This is because, unlike LASIK, PRK does not leave a protective flap over the cornea.

Fully stabilized vision will be achieved in about a month. You may experience some mild pain after surgery, so Dr. Cohen will prescribe pain medications to relieve discomfort.
