Abstract

Purpose: To evaluate CORNEAL TOPOGRAPHIC CHANGES and induced corneal astigmatism after SCLERAL BUCKLING SURGERY. Methods: As an interventional case series, patients referred to us from February to November 2002, with rhegmatogenous retinal detachment were scheduled for SCLERAL BUCKLING SURGERY. The exclusion criteria were: history of pervious scleral buckling, any corneal disease visible on slit lamp biomicroscopy, and any ophthalmic operation in the previous 6 months. According to the extent of surgery, the patients were divided into 4 groups: A) 3600 encircling band + buckling, B) segmental buckling + encircling band, C) radial buckling, and D) local circumferential buckling. Videokeratography was done for all patients before, and then one and 3 months after scleral buckling. Corneal astigmatism, mean keratometry, SRI (surface regulatory index), SAl (surface asymmetry index), PVA (potential visual acuity) were evaluated at each visit. Results: From 56 patients enrolled in this study, 39 patients completed follow up. There were 29 (74.4%) males and 10 (25.6%) females with mean age of 50.35±20years. The patients consisted of 3 (7.65%) in group A, 30 (76.92%) in group B, 4 (10.25%) in group C, and 2 (10.25%) in group D. Statistically significant differences regarding SRI, SAl, PVA (in Log MAR) from baseline measurements were observed in all patients at one and 3 months postoperatively. In spite of increasing corneal astigmatism, there were no statistically significant differences in mean keratometry after SCLERAL BUCKLING SURGERY. In group B, the results were the same as overall results. In groups A, C, and D the above variables were increased postoperatively. Conclusion: Irregular astigmatism is induced after SCLERAL BUCKLING SURGERY that remains up to 3 months. It is one of the important causes of decreased visual acuity postoperatively.
