[15 months photorefractive keratectomy at the Munster University Eye Clinic]

We performed a photorefractive keratectomy (PRK) in 51 myopic eyes of 34 patients. Cortisone-responders were excluded. All patients were unable to tolerate contact lenses. The intended correction was between -1.75 and -7.0 D. None of the patients demonstrated a decrease in visual acuity at its highest level of correction. The maximum haze was +1. No eye had to be reoperated upon. Nine months after PRK, the maximum deviation from the intended correction was 2 D in a -6.5 D correction. After 12 months, however, we found a regression of 2 D without signs of keratoconus or increase of haze in 2 patients.
