Collectively known as surface ablation procedures, PRK, EPI-LASIK, and LASEK are for patients who are not LASIK candidates. Corneas that are thin, steep, flat, or irregular in shape may not respond to LASIK in an ideal way. Surface ablation techniques may also be a better treatment for those with moderately dry eye because fewer corneal nerves are impacted when compared to LASIK. The range of correction with PRK, EPI-LASIK and LASEK is similar to standard LASIK. Since less corneal tissue is removed with PRK, EPI-LASIK and LASEK, thinner corneas can be treated. Like LASIK, PRK and EPI-LASIK are permanent.
A significant advantage of EPI-LASIK, PRK, and LASEK over LASIK is the elimination of risks associated with creating a corneal flap; however, a significant disadvantage of surface ablation technology is the slower visual recovery. With LASIK, typical visual recovery is about 90% in a day whereas with EPI-LASIK, PRK and LASEK typical visual recovery takes about a week. Please note that vision continues to improve for many weeks after the procedure with any form of laser vision correction. Please read the criteria that we look for in a good candidate.

About the procedure
PRK has the longest track record in the field of laser vision correction with more than 20 years of results worldwide. It differs from LASIK in that the thin skin layer (epithelium) of the cornea is manually removed in sections prior to applying the custom wavefront correction.
In any case, after the skin layer is removed, the customized wavefront correction is applied to the eye followed by the placement of a specialized transparent bandage to promote healing. After several days the epithelium is regenerated by the body.
Anesthetic eye drops are used to numb the eye while an eyelid holder maintains the eye in an open position. A mild relaxant medication is also given for patient comfort. Please note there are absolutelyno injections. Sophisticated tracking devices (developed by NASA) on the laser follow the natural eye movements during the very brief (about 1 minute) customized resurfacing.
The total surgical time is often about 5 minutes per eye. After a brief rest, patients leave the office wearing sunglasses. Because vision is initially blurry, it is required that the patient be accompanied home. There is discomfort for a few days after the procedure, most notably tearing, light sensitivity, and a sensation that there is something in the eye. Pain-relieving eye drops and over-the-counter oral pain relievers alleviate much of the discomfort. We ask that you rest as much as possible during that time.
More than 99% of patients obtain vision within 2 lines of 20/20 and can perform exceedingly well in most or all activities. There are side effects associated with PRK, LASEK andEPI-LASIK. Most side effects are temporary but some can be chronic. The most common side effects are dry eye, nighttime glare, and the need for a fine-tuning procedure.
The goal of refractive surgery is to eliminate or reduce any dependence on corrective lenses, but the result is not guaranteed. We are thrilled to report that satisfaction rates at Kelly Laser Center are very high.
Dr. Kelly and staff will discuss more details with you during the consultation to allow you to make an informed decision about whether to proceed. Be sure to have all questions answered to your satisfaction regarding the examination and consent forms.
If you have been told that you are a non-candidate for LASIK, please contact Kelly Laser Center today to schedule a thorough eye exam. We will determine if you are eligible for PRK, LASEK, EPI-LASIK or Implant Vision Correction at Kelly Laser Center’s Manhattan and Long Island offices.
