The clinical study of the ARRAY multifocal intraocular lens implantation

Objective To evaluate the visual functiona and complications after phacoemulsification combined with implantation of a multifocal intraocular lens(MIOL) in patients with senior cataract.Methods 101 patients(137 eyes)with senior cataract were divided into two groups,Group Ⅰ:50 cases(71 eyes),Array SA-40N MIOL was implanted after phacoemulsification,the average time of follow-up was 17 68±4 42 months;Group Ⅱ:51 cases(66 eyes),SI-40N monofocal intraocular lens(SIOL)was implanted after phacoemulsification,the average time of follow-up was 23 04±4 70 months.The uncorrected and best-corrected distance and near visual acuities and complications after operation were observed.Results Group Ⅰ had better uncorrected near vision and best distance-corrected near visual acuity than Group Ⅱ( P 0 001),uncorrected distance visual acuity,best-corrected distance visual acuity and best-corrected near visual acuity in Group Ⅰ was similar to Group Ⅱ( P 0 05).A higher proportion in the multifocal group achieved 0 5 or better uncorrected near visual acuity and 0.5 or better best distance-corrected near visual acuity than in the monofocal group(85.9% versus 16.7% and 90.1% versus 18.2%).There have been no serious postoperative complications in either group.Conclusions The results of this study indicate that Array multifocal IOL implantation may provide a better way to help patients with cataract to obtain satisfying distance visual acuity,better uncorrected near visual,less spectacle dependency and high quality of life.
