PRK Surgery

Tired of depending on expensive contact lenses and cumbersome glasses in order to see clearly?

PRK laser eye surgery, or photorefractive keratectomy, can sharpen your vision and make prescription eyewear unnecessary.

Learn why Dr. Bruce Cohen of Cohen Eye Associates, Limited in St. Louis, MO, is the best ophthalmologist to perform your PRK procedure...

What Exactly Is PRK?

PRK is a laser eye surgery that corrects nearsightedness, farsightedness, and astigmatism by reshaping your cornea and allowing light to focus properly on your retina. It is similar to LASIK; the difference is that instead of creating a tissue flap in the cornea, the entire outer layer of the cornea is removed. Healing after PRK takes a few days longer than healing from LASIK, but the procedures are equally effective.

If you have been told that you don't qualify for LASIK due to having thin corneas or working in a profession with a high risk of corneal injury, PRK may be a suitable way to help you reduce or eliminate your need for glasses and contacts. During a consultation, Dr. Cohen can determine if this or another laser eye surgery is right for you.

CustomVue Treatment for Better Results

We use the Visx Wavescan system to detect even the smallest refractive errors our PRK surgery patients may have. The combination of this wavefront device and Star S4 Laser (known as CustomVue treatment) allows Dr. Cohen to accurately assess and treat previously undetectable visual disorders.

The FDA conducted clinical trials on patients who received refractive surgery using the Visx CustomVue procedure, discovering that 94% achieved vision that was 20/20 or better. Additionally, patients were four times more likely to say they were very satisfied with their new night vision than they had been with glasses or contact lenses.

I have used this practice for probably 25 years or longer. They have never missed with my prescription, not once. They are very thorough.The person who actually assists with the frame selection does an awesome job. She considers the shape, color and how the prescription will work with the size and shape of the frame, and does not just push what is popular. Her work is very individually tailored.

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 than LASIK. Members of the military and similar occupations might also decide PRK is a better fit than LASIK 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 eye 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.

PRK Candidacy

One of the first areas Dr. Cohen will assess is whether or not you have enough corneal tissue to support the reshaping of your eye. He will also evaluate your eye tissue for its general health, and likelihood of seamless healing. His many decades as a renowned ophthalmologist also give him insight into how your personal medical history will impact your PRK success. 

The best way to determine if you are a great candidate for transformative PRK surgery is having a consultation with Dr. Cohen at our St. Louis office. He understands the key factors to evaluate and can create a trusting surgeon-patient relationship from day one. He can also let you know if LASIK or another procedure is more suitable for your needs.

Photorefractive Keratectomy 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 and eye drops as needed to relieve discomfort.

Photorefractive Keratectomy Following Cataract Surgery

Cataracts can often cause cloudy vision. In some cases, patients require cataract surgery to return to clear sight. Unfortunately, some cataract surgeries can result in residual refractive errors that lead to persistently obstructed vision. The good news is that we can perform PRK to correct refractive errors you may be experiencing following cataract surgery elsewhere.

A comprehensive study published in the International Journal of Ophthalmology found PRK to be safe and effective for correcting refractive errors caused during cataract surgery. Visual improvements were found to be stable and long-term for patients with and without astigmatism.
