PRK SURGERY

The PRK laser is computer-controlled and programmed by an Eye Surgeon to specifically address a patient's own unique corneal shape and refractive error.

The laser produces a highly concentrated beam of light which flattens the front surface of the cornea by removing micro-thin layers of tissue.

What is PRK?

Photorefractive Keratectomy, or PRK, is an outpatient corneal surgery that can reduce or correct mild to moderate myopia. This is done by use of a laser that precisely reshapes the cornea. The goal of PRK is to reduce or eliminate dependency on glasses or contact lenses.

Most of the people who have had PRK report they no longer need to wear glasses or contacts. In a large clinical trial, two-thirds of the patients who had PRK can see 20/20 or better without corrective lenses. 95% can see at least 20/40, well enough to pass a driver's test.

Risks

Although unlikely, there is a chance that complications may arise as a result of having PRK. Anyone considering the surgery should weigh the potential risks against the benefits of PRK.

Undercorrection

It's possible that the PRK treatment could result in undercorrection and some degrees of nearsightedness may remain. Retreatments often correct this problem.

Overcorrection

It's possible that overcorrection could occur; meaning patients may need to wear glasses or contact lenses after PRK. Overcorrections are generally not retreated.

Night Vision Difficulties

Some PRK patients report difficulty with night vision. For instance, tasks performed without visual difficulty during the day are more difficult in low light or at night.

Loss of Best Corrected Vision

A small percentage of PRK patients experience a decrease in best corrected vision. This means if they could see images with a certain clarity wearing glasses before PRK, they might not be able to see as well, even with glasses, after PRK.

Other Risks

As with all surgeries, there is the rare possibility of infection or drug reaction that could cause loss of vision. Some people find they need reading glasses at an earlier age after PRK even though they did not need them before. Whether they've had PRK or not, most people need to wear reading glasses after the age of 40.

How to Make an Informed Decision About PRK

PRK is an elective procedure, so be sure to make an informed decision. The most satisfied patient is one who has realistic expectations and a thorough understanding of the risks and possible complications of refractive surgery. If you are considering the surgery, be certain to talk with your Eye Care Professional. The following are questions your Eye Care Professional will be able to address to help you make an informed decision.

Am I a good candidate for PRK?
What are the benefits of the surgery?
What are the alternatives to PRK, both surgical and non-surgical?
What are the possible complications and side effects of the surgery?
Will I need additional surgery after the initial procedure?
Will I still have to wear glasses after PRK?
Will I need reading glasses as I age?

Questions to ask yourself before you make a decision:

Will I be satisfied with PRK if I still need to wear eyeglasses all or part of the time?
Can I tolerate the temporary discomfort and inconvenience that may follow the PRK operation?
Consult Your Eye Care Professional.

Guidelines for Appropriate Referral of Persons with Possible Eye Diseases or Injuries

Policy

The American Academy of Ophthalmology supports the concept of prompt appropriate referral of persons to a doctor of medicine or osteopathy (M.D. or D.O.), Preferably to an Eye M.D., when certain signs are observed and/or certain symptoms are reported of possible eye disease or injury.

Background

Many eye diseases, systemic diseases, and injuries that affect the eyes may begin with subtle signs and either minimal or barely detectable symptoms. Most of these diseases and injuries require prompt and appropriate medical treatment in order to minimize risks of impaired vision or even blindness. Ophthalmologist are medical specialists qualified by education, training, and clinical experience to provide total eye care, which includes a vision examination (refraction), a medical eye examination, and necessary medical and surgical care and treatment.
