How Does PRK Work?

PRK may be the appropriate treatment for patients who are not good candidates for LASIK. If your eyes cannot bend the light correctly, the cornea must be reshaped to function correctly, focusing light on the retina. Patients with thinner corneas are often a candidate for this vision correction treatment, as an alternative to LASIK, as far less of the eye structure is removed during the procedure.

What is Epi-LASIK? Should I Get PRK?

If you have dry eyes or thin corneas and want to have refractive surgery to correct your vision, PRK may be a good choice for you. Patients with an extremely active lifestyle or job may be better treated with PRK than with LASIK, as PRK does not require the creation of a flap, which for active people poses a minor risk of becoming dislodged, requiring additional treatment to resolve.

Is PRK Right for Me?

At Pacific Vision Institute in San Francisco, our advanced diagnostics will allow us to determine which vision correction procedure will achieve the best results in your case. Those who have dry eyes or thinner corneas may require PRK to correct vision, rather than LASIK.

Who is a Candidate for PRK?

The first step in determining the right procedure to correct your vision is a full range of diagnostic testing, and a review of your medical history.

  • 18 years or older
  • Stable glasses prescription, for at least one year
  • Healthy corneas and eyes overall

Some patients will require an alternative to PRK for vision correction, including:

  • Those whose vision continues to change
  • Patients with a health condition that could affect healing
  • Patients who scar easily
  • Patients who are suffering advanced glaucoma
  • Those with cataracts (must be treated first)

What is Epi-LASIK?

The epithelium is the most outer layer of your cornea. It is an important part of the eye structure that acts as a barrier, protecting the eyes against fluid loss or the penetration of pathogens. In Epi-LASIK, this area of the eye is protected. A flap is created with a specialized surgical tool, a microkeratome, that has been customized to carefully lift this part of the eye.

Epi-LASIK may be performed to preserve the epithelial cells so that part of the eye will adhere to the structure once replaced. Depending upon the condition and need of the patient, the epithelium may be removed during the procedure.
