Pefractive Changes After Encircling Scleral Buckling Surgery

ABSTRACT

Sixty rhegmatogenous retinal detachment patients who had received retinal detachment surgery by same surgeon at Yongdong Severance Hospital from Feb. 1990 to Feb. 1991 were evaluated prospectively to detect the refractive changes after operation. The authors studied the postoperative retinoscopic findings 3 months after retinal detachment surgery, and compared with preoperative refractive errors. The results were as follows; 1. The encircling scleral buckling with 3mm silicone sponge increased an average induced myopia of -1.63 diopter. 2. The segmental buckling increased an average induced myopia of -0.50 diopter. 3. The combined operation of encircling buckling and radial buckling increased an average induced myopia of -2.75 diopter. 4. The pneumatic retinopexy with SF6 gas caused never postoperative refractive changes.
