Welcome to the Kagan Institute, where vision restoration and eye health are at the forefront of our mission. One of the cutting-edge procedures we offer here is Photorefractive Keratectomy, commonly known as PRK. This comprehensive guide aims to give you an in-depth understanding of PRK, from the science behind it to the benefits you stand to gain. Dr. Kagan and the team are always here to help you make the best decision for your vision.

The Underlying Science

Photorefractive Keratectomy, or PRK, is a type of refractive surgery designed to correct vision issues like nearsightedness, farsightedness, and astigmatism. Unlike LASIK, PRK doesn't involve creating a flap in the cornea. Instead, the procedure involves gently removing the outer layer of the cornea, known as the epithelium, before reshaping the corneal tissue underneath using an excimer laser. This highly specialized laser employs ultraviolet light to meticulously remove microscopic layers of tissue, thereby correcting the curvature of the cornea to improve vision.


The Benefits

Precision and Safety: PRK is considered one of the most precise and safest options for vision correction, offering an excellent track record since its FDA approval in 1995. The absence of a corneal flap eliminates any flap-related complications, making it a suitable option for people with thin corneas or active lifestyles or those risk-averse to a flap procedure.

Long-Term Results: Most patients experience significant improvement in their vision and can go without corrective lenses post-procedure. Over 90% of PRK patients attain 20/40 vision or better, which is the legal standard for driving without corrective lenses in most jurisdictions.

Minimal Discomfort: After the procedure, you may experience some discomfort, but this is often temporary. In most cases, patients feel back to normal within a week.


LASIK (Laser-Assisted in Situ Keratomileusis) is another popular refractive surgery. While both procedures have the same end goal of vision correction, they differ in technique. LASIK involves creating a flap in the cornea to reach the underlying tissue, whereas PRK removes the corneal surface layer entirely. This makes PRK a better choice for those with thin/abnormal corneas or those risk-averse to a flap procedure. However, PRK may involve a slightly longer recovery period than LASIK.


Patient Experience at Our Office

When you come to the Kagan Institute, Dr. Kagan will conduct an initial consultation to evaluate your eye health and determine your suitability for PRK. If you're a good candidate, we'll schedule your procedure. On the day of the surgery, we use numbing drops to ensure you’re comfortable throughout the quick, 10-15 minute procedure per eye. Post-surgery, you'll need a ride home, and you can expect to return to most normal activities within a week or so.

Frequently Asked Questions

Is PRK painful?

Most patients experience only mild discomfort, which usually subsides within a week.

How long is the recovery period?

Generally, most patients return to their normal activities within a week. However, complete healing can take a bit longer.

Is PRK suitable for everyone?

While PRK is an excellent option for many, it's not suitable for everyone. A comprehensive eye exam with Dr. Kagan will help determine if PRK is the right choice for you.

Are the results of PRK permanent?

For most patients, the results are long-lasting. However, as you age, you may still need reading glasses due to natural changes in your vision due to presbyopia.


PRK is a highly effective, long-term solution for vision correction. Its safety profile and precision make it a compelling choice for those who are looking for a life less dependent on glasses or contacts. Here at the Kagan Institute, we are committed to providing you with the highest standard of care, from initial consultation to post-surgery follow-up.
