To evaluate the single zone photorefractive keratectomy for the correction of myopia using excimer laser.
Summit OmniMed excimer laser was used to treat 167 myopic eyes that were divided in three groups: low myopia (less than -5.0 D), moderate myopia (from - 5.25 D to -7.00 D), and high myopia (more than -7.0 D).
One month after surgery, 100% of the eyes in the low myopia group, 60% in the moderate myopia, and 57% of the high myopia were within 1 D of emetropia. Uncorrected visual acuity of 0.8 or better were achieved by 93%, 80%, and 28.6% of these eyes respectively after nine months of follow-up. The most important post operatory complication was corneal haze that was present in 3.06%, 10.5% and 29. 0% of the eyes, respectively.
Based on these results, single zone photorefractive keratectomy is a safe and efficient procedure for the treatment of low and moderate myopia.
