What is PRK?
While not everyone is a candidate for LASIK surgery, there is still hope for people who wish to regain quality vision. Photorefractive Keratectomy, or PRK, is performed at Colorado Cataract Laser & Vision, and is a highly effective alternative to LASIK surgery. PRK was approved by the FDA in 1995, and was the first refractive surgery to use a laser. PRK can help correct nearsightedness, farsightedness as well as astigmatism.
Is PRK right for me?
Common symptoms that lead to PRK include:
- Tired of glasses or contact lenses.
- Cornea’s too thin for LASIK Surgery.
- Irregular or scarred cornea.
- Poor depth perception.
If you are not a candidate for LASIK and answered yes to one or more of these questions, contact us today to setup a consultation!
What to expect on the day of PRK surgery
During the Surgery
The PRK procedure from beginning to end takes about 10 minutes per eye.
The Excimer Laser
The excimer laser generates its power from light in the ultraviolet range, and cannot be visualized by the human eye. The laser causes miniscule amounts of corneal tissue to dissociate at a microscopic level. The laser actually does not generate any hear, and therefore no tissue damage occurs during this process. Microscopic layers of tissue, approximately 1/10th the width of a human hair, are removed.
