The outcome of reoperation following photorefractive keratectomy.
PURPOSE: The aim of this study was to assess the outcome of reoperation following photorefractive keratectomy related to different techniques. MATERIAL AND METHODS: 265 retreated eyes were divided into 5 groups; low to moderate myopia, high myopia, enlargement, abrasion, and non-compliance. The low to moderate group was further subdivided into 5 categories based on the surgical approach of the reoperation. Outcomes were compared at 12 months after reoperation. RESULTS: There was no statistically significant difference in the median refraction prior to initial PRK, before reoperation, and after reoperation between the 5 categories 66%, of all reoperated patients achieved an uncorrected visual acuity of 0.5 or better after 12 months. 72% had a postoperative refraction between +/- 1 diopter. The other 4 groups were not statistically analyzed due to the wide variety of patients included and non-compliance. CONCLUSION: In low to moderate myopes, approximately 97% achieve uncorrected visual acuity of 0.5 or better following PRK, including one reoperation.[1]References
