PRK Laser Surgery

PRK (Photorefractive Keratectomy) Laser Surgery

Our practice’s philosophy is to educate our patients while providing the safest, most advanced medical and surgical eye care. We believe that a thorough understanding of an existing medical condition allows the patient to take a more active and knowledgeable role in making informed decisions about their treatment options.

Providing proper informational tools and open communication between the doctor and patient contributes to the overall healing process and optimizes the potential for a more successful outcome.

What is PRK? PRK

Laser vision correction involves changing the shape of the central (6mm) corneal surface area with excimer laser energy. The excimer laser produces a powerfully focused beam of ultraviolet light in a series of rapid pulses that remove small and precise amounts of corneal tissue in correcting common refractive errors such as nearsightedness, farsightedness and astigmatism.

The excimer laser energy does not penetrate into the eye and leaves the internal eye structures undisturbed. The entire procedure takes approximately 15-20 minutes with only about 40-60 seconds of actual laser time. Local anesthetic drops are used to minimize discomfort.


PRK vs. LASIKUnlike LASIK laser surgery, PRK does not involve creating a flap of corneal tissue with a microkeratome before treating with the excimer energy. LASIK offers a quicker healing time, but there is a greater chance of infection and the potential for other flap-related complications.

As with any surgical procedure, there are risks associated with both types of laser vision correction that need to be discussed with your doctor prior to treatment. A pre-surgical examination will be required to determine if your eyes are healthy and suitable for the surgery. There are specific surgical contraindications and refractive error limitations that need to be considered in determining whether
or not you are a good candidate for the procedure.

It is important to remember that laser vision correction may only reduce and not completely eliminate your dependency on glasses or contact lenses, especially for patients over 45 years of age.
