Photorefractive Keratectomy (PRK)
Photorefractive Keratectomy (PRK) was the predecessor to LASIK and remains one of the most trusted laser eye surgery procedures. Like LASIK, PRK uses an advanced excimer laser to reshape the surface of your cornea, allowing your eyes to bend light correctly for the first time. PRK is capable of treating many different cases of myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

How Does PRK Work?
In LASIK eye surgery, a hinged flap is created in the outer layer of your cornea to provide the laser with access for treatment. Once the procedure is complete, the flap is replaced and allowed to heal.
In PRK, the entire outer (epithelial) layer of your cornea is removed in order to expose the treatment area. After a few days, this layer will naturally regenerate. PRK is often recommended to patients whose corneas are too thin to support a LASIK flap.
Some of the advantages of PRK include:
- No risk of flap complications
- Reduced risk of corneal thickness being compromised
- Less depth of laser treatment compared to LASIK
PRK Recovery and Results
Since the outer layer of your cornea is completely removed in PRK, your recovery period will be slightly longer than LASIK and may involve some mild discomfort for a few days. Although your vision takes longer to stabilize after PRK, the final results are just as effective as LASIK.
Nearly all patients achieve 20/40 vision or better after PRK surgery, and many people are able to achieve 20/20 vision. While some patients may still need to wear contact lenses or glasses in some situations, your dependence on eyewear will be drastically reduced.
If you have further questions about PRK, please contact Brooks Eye Associates or call (972) 736-9347 today to schedule a screening. We serve patients in North Texas, including Plano, Frisco, McKinney, and Dallas.
