SN6AD1+3.0D非球面多焦点人工晶体植入术后的临床观察

探讨分析SN6AD1+3．0D非球面多焦点人工晶体植入术后的视功能。选择老年性白内障患者48例(60眼),分为多焦点组(植入SN6AD1+3．0D多焦点人工晶体,30眼/28例)和单焦点组(植入SN60WF单焦点人工晶体,30眼/20例)。术后观察两组裸眼及最佳矫正远、中、近视力,拟调节力及视功能的问卷调查。术后两组裸眼中视力、近视力比较,多焦点组优于单焦点组；多焦点组的拟调节力为(2．65±0．48)D,单焦点组为(0．38±0．15)D；阅读脱镜率多焦点组达86%,单焦点组13%。

Clinical observation of SN6 AD1+3 . 0 D aspheric multifocal intraocular lens implantation in cataract surgery

To evaluate the visual performance of aspheric multifocal intraocular lens (SN6AD1+3. 0D) implanta-tion in age-related cataract surgery. Forty-eight patients (60 eyes) with age-related cataract were divided into two groups, 28 patients(30 eyes)in the multifocal group (implanted with SN6AD1+3. 0D multifocal intraocular lens), and 20 patients(30 eyes)in the monofocal group (implanted with SN60WF monofocal intraocular lens). The uncor-rected and the best corrected distance,intermediate and near visual acuity and the amplitude of pseudoaccommoda-tion were measured after surgery,and the subjective visual performance was evaluated by the questionnaire. The un-corrected intermediate and near visual acuity were statistically better in the multifocal group than the monofocal group. The amplitude of pseudoaccommodation of multifocal and monofocal group was (2. 65 ± 0. 48) D and (0. 38 ± 0. 15)D. The spectacle independent rates of multifocal and monofocal group were 86% and 13% respectively.
