Visual function with bilateral implantation of AcrySofReSTOR multifocal intraocular lens

Abstract

Objective To evaluate the effectiveness and security after implantation of multifocal intraocular lens in Chinese,by comparing the visual function of bilateral implantation of the new apodized diffractive AcrySof ReSTOR multifocal intraocular lens （MIOL） and Acrysof Natural, Monofocal intraocular lens （MoIOL） Methods Forty-three patients with age-related cataract were divided into two groups with random principia： bilateral Acrysof ResToR multifocal IOLs or the monofocal AcrySof Natural lols. The Acrysof ReSTOR group included 18 patients （36 eyes）, and reference group-AcrysofNatural group （MoIOL） included 25 patients （50eyes）. Measurements were taken after operation, including uncorrected distant vision acuity （UCDVA）, uncorrected near vision acuity （UCNVA）, best corrected distant vision acuity （BCDVA）, best corrected near vision acuity （BCNVA）, distant corrected near vision acuity （DCNVA）, Intermediate Vision （40, 60,80 cm）, contrast sensitivity （CS） and visual symptoms. Results UCNVA, DCNVA and Intermediate Vision （40, 60, 80cm）were significantly higher in the MIOL group （P〈0.05）. No statistical difference was noted between 2 groups with the CS. The adverse symptoms of the MIOL group were slight. The dependence of glasses of the MIOL was 80%. The MIOL group provided better patient satisfaction. Conclusions Bilateral implantation in patients with the new apodized diffractive MIOL multifocal intraocular lens （IOL） appears a better outcome in near and intermediate vision, slight visual symptom, improve the quality of life after surgery.
