Abstract

Background and Objectives: Refractive errors have relatively higher prevalence in populations and MYOPIA is byfar the most of them (25%). Many efforts have been made for correction of MYOPIA. Radial Keratotomy (R.K) is one of them. The aim of this study was to evaluate the longterm refractive, keratometric and visual results after RK at Alavi Eye Hospital in Tabriz.Materials and Methods: This prospective study was done from 1997 to 2001 on 50 eyes from both sexes. In all patients slit lamp examination, fundus exam, refraction with and without cycloplegia, ultrasonic pachymetry and corneal topography were done and recorded. Through local anesthesia with a 0.2mm diamond knife, American incisions performed with standard nomograms (with regard to the age , sex , degree of MYOPIA, pachymetry and topography). Slit lamp examination, visual acuity, checking refraction and topography were done in first week and 3 months after operation and in year 2001, as well as results analyzed with statistical methods.Results: the mean age of patients was 29 (74% male and 26% female). The mean duration of follow-up was 10.5 months. The average central pachymetry was 536.68µ, and had not meaningful relation with the degree of MYOPIA. Average keratometry before and after operation was 43.75D and 40.67D respectively. The average MYOPIA before surgery was -5.07 after which decreased to -1.50. Uncorrected visual acuity in 80% of the eyes was 8/10 or better. The most complaints after surgery were disturbances in night vision and blurred distance vision in 13 out of cases. Hyperopic shift was not seen and undercorrection was the most prevalent complication.Conclusion: With regard to the successful RK in correction of mild to moderate degrees of MYOPIA, it is effective in cases of spectacle intolerance or vocational limitations.
