Effect of fine capsule treatment on the visual quality of diffractive multifocal intraocular lens

Abstract

AIM: To investigate the effect of fine capsule treatment on the visual quality of diffractive multifocal intraocular lens.METHODS: Ninety-eight patients(120 eyes)with DMIOL implanted in cataract Department of Hebei Eye Hospital from March 2017 to April 2018. They were randomly divided into A group and B group. 60 eyes in each group. Group A patients were treated with anterior and posterior capsular polishing and posterior continuous circular capsulorhexis, while in B group the fine capsule treatment was not performed. The UCDVA, UCIVA, UCNVA, visual quality, intraocular lens neutrality and PCO incidence were compared 6mo after operation.RESULTS: At 6mo after operation, UCDVA, UCIVA and UCNVA in group A were superior to those in group B. The difference was statistically significant(PPCONCLUSION: In order to enhance the stability of IOL and maintain the long-term transparency of the optic axis, we performed fine polishing of the anterior and posterior capsule and continuous circular capsulorhexis of the posterior capsule. These could improve the visual quality and satisfaction of patients after surgery.
