Purpose:A prospective study was conducted to compare the refractive changes after three different types of scleral buckling surgery. Methods: 100 eyes of 100 patients were divided into three groups according to the type of buckling procedure performed: Group 1, encircling scleral buckling (42 patients); Group 2, encircling with vitrectomy (30 patients); Group 3, encircling with additional segmental buckling (28 patients). Refractive examinations were performed before and at 1, 3 and 6 months after surgery. Results: The amount of induced astigmatism was more significant in Group 3. Changes in spherical equivalent and axial length were more significant in Group 3. No statistical significance was found between Groups 1 and 2.Conclusion: All three types of scleral buckling surgery were found to produce refractive changes. A correlation exists between additional segments and extent of refractive change.
