Abstract

We evaluated the safety, stability, predictability and efficacy of photorefractive keratectomy (PRK) with Schwind excimer laser for one year. We performed one-step procedures on 114 eyes of 92 patients. They were divided into three groups according to their manifest refractive error (spherical equivalent): Group ! (<-5 D, 39 eyes) , Group I (-5. 01 to -8 D, 40 eyes) , or Group III (>-8.01 D, 35 eyes). One year after PRK, uncorrected visual acuity of 0.8 or better was achieved in 95% of eyes in group I, 97% of eyes in group I and 63% of eyes in group III. In the group I , 90% of eyes were within +/-1 D of attempted correction, as were 95% in group II and 63% in group III. Complications were corneal haze above grade 2(8.8%), temporarily increased intraocular pressure (18.4%), central island (14.9%), eccentric ablation more than 0. 5mm(34.2%) and halo (0.9%). We conclude that the Schwind excimer laser PRK appears to be 8 safe and relatively accurate procedure to correct low to moderate myopia, but long-term and more frequent follow-up is needed for high myopia.
