What Is PRK?
PRK, or photorefractive keratectomy, is a type of laser eye surgery that reshapes the cornea to correct vision issues such as nearsightedness, farsightedness, and astigmatism. Unlike LASIK, PRK does not involve creating a corneal flap, making it an excellent option for patients with thinner corneas or those who may not be ideal candidates for LASIK. At BVA Advanced Eye Care, we offer PRK as a safe and effective alternative to help patients achieve clearer vision without the need for glasses or contact lenses. To learn more about PRK and our other laser eye surgery options, contact one of our offices in Oklahoma City, OK to schedule a consultation.

How Is PRK Performed?
PRK is performed by first removing the thin outer layer of the cornea, called the epithelium, to expose the underlying corneal tissue. Then, a specialized excimer laser is used to reshape the cornea, correcting the refractive error. Unlike LASIK, PRK does not require the creation of a corneal flap. After the procedure, a protective contact lens is placed over the eye to promote healing, and the epithelium naturally regenerates within a few days. The procedure typically takes about 15 minutes per eye, and although the recovery is slightly longer than LASIK, PRK offers excellent long-term results.
What Are the Benefits of PRK?
PRK offers several advantages for individuals seeking long-term vision correction:
- No risk of complications related to a corneal flap
- Ideal for patients with thin or irregular corneas
- Provides lasting results for nearsightedness, farsightedness, and astigmatism
- Lower risk of post-operative dry eye
- Suitable for those with active lifestyles due to the absence of a corneal flap
PRK FAQ
How is PRK different from LASIK?
PRK does not require a corneal flap. Instead, the surface layer of the cornea (epithelium) is removed, and a laser reshapes the underlying tissue. This makes PRK suitable for patients with thinner corneas or those prone to dry eye.
Are there any risks or side effects with PRK?
Common side effects include temporary dry eyes, light sensitivity, and halos around lights at night. Serious complications are rare and can often be prevented with proper care and follow-up.
Will I experience vision fluctuations after PRK?
Yes, vision fluctuations are normal during the healing process. Your eyesight may seem clearer some days than others as your cornea stabilizes, but this typically resolves within a few weeks to months.
How does recovery from PRK differ from LASIK?
Recovery from PRK takes longer than LASIK because PRK involves removing the outer layer of the cornea, which needs time to regenerate. While vision improvement begins within a few days, it may take several weeks to achieve full clarity. During this period, patients may experience mild discomfort and sensitivity to light, which can be managed with prescribed eye drops.
Can PRK treat high levels of nearsightedness or farsightedness?
PRK can correct a range of refractive errors, including nearsightedness, farsightedness, and astigmatism, but it may not be suitable for extremely high prescriptions. During your consultation, your ophthalmologist will evaluate the severity of your refractive error and determine if PRK is the best option for achieving your vision goals.
Are there any lifestyle adjustments after PRK surgery?
Yes, after PRK surgery, you’ll need to avoid activities that could strain or expose your eyes to potential harm, such as swimming, using hot tubs, or engaging in contact sports, for several weeks. Wearing UV-protective sunglasses is crucial to shield your eyes during recovery. Your ophthalmologist will provide detailed post-operative care instructions tailored to your lifestyle.
