인공수정체의 종류에 따른 예측굴절력과 실제굴절력의 차이에 대한 연구

Abstract

Purpose: To evaluate the difference between the predicted and actual refraction among the intraocular lenses having different materials and shapes of optic and haptic. Methods: We retrospectively analyzed the cases of 680 eyes with normal range of axial length (21-26mm),which underwent phacoemulsification and posterior chamber 10L implantation, and had at least 2 months fo11ow up period, divided by 4 groups according to the types of 10L used. Results: Mean age of the subjects was 68.9±10.8 years with 197 eyes (29%) of male and 483 eyes (71%)of female. The difference between the predicted and 2 month-postoperative refraction was +0.01 (SI40NB),-0.01 (LI61U), -0.45 (C3lUB), +0.05 (MA60BM) diopters, respectively. C31UB group represented the myopic shift of -0.45D range and other groups showed no statistically significant difference. Conclusions: There was no effect of optic materials on the acquisition of goal diopter, MA60BM, SI40NB, L161U showed high accuracy of predictiveness. The cause of myopic shift represented in C3lUB group might be the differences of the haptic material, optic-haptic junction, or overall diameter.
