The effect of clear lens phacoemulsification with multifocal intraocular lens implantation for high myopia

Abstract

Objective To assess the visual efficacy after clear lens removal with multifocal intraocular lens implantation in high myopia. Methods A total of 90 eyes from 62 patients undergoing phacoemulsification received intraocular lens implantation based on the principle of voluntary. Thirty-two patients (48 eyes) who had implantation of Array SA-40N MIOL were randomized into experimental group, 30 patients (42 eyes) who had implantation of ALCON SA60AT SIOL were randomized into control group. Distance visual acuity and near visual acuity, stereopsis acuity and visual field were measured in 18 months postoperative. Visual symptoms and quality-of-life were observed by questionnaire. The mean follow-up was 32 months (18 to 48months). Results MIOL eyes showed excellent UCDVA as SIOL eyes (0.89±0.34 versus 0.81±0.22, P >0.05) and better UCNVA than later (0.71±0.20, 0.39±0.21, P <0.01). Patients with bilateral MIOL implantation had better stereoscopic visions than the one with bilateral SIOL implantation. Most patients were satisfied with the result of the operation. The spectacle independence was 53.1% in MIOL group. No severe surgical complications occurred. Conclusions Phacoemulsification with the implantation of multifocal intraocular lens in high myopia is safe, effective, but spectacle independence proportion in high myopia is low.
