摘　　要：目的比较白内障超声乳化联合植入Acrysof ReSTOR(多焦点人工晶状体)及Acrysof Natural(单焦点人工晶状体)术后人工晶状体眼的视功能状态,评价多焦点人工晶状体的临床效果及安全性。设计非随机化临床试验。研究对象53例(61眼)老年性白内障患者按自愿选择的原则分为两组,多焦点人工晶状体组28例(31眼),单焦点人工晶状体组(对照组)25例(30眼)。方法全部患者行白内障超声乳化吸除术,按分组植入不同类型的人工晶状体。术后1周、1个月、3个月观察术眼远、近视力及焦点深度范围。主要指标非矫正远、近视力,最佳矫正远、近视力．矫正远视力下近视力,焦点深度范围。结果多焦点人工晶状体组患者术后3个月平均裸眼远视力0．90±0．15,平均裸眼近视力0．70±0．19,矫正远视力下近视力0．73±0．21,焦点深度范围5．5D(+1．5D～-4．0D)。术后1个月时裸眼远、近视力较1周时显著提高(P=0．00l,P=0．000)。单焦点人工晶状体组患者术后3个月平均裸眼远视力0．84±0．14,平均裸眼近视力0．36±0．10,矫正远视力下近视力0．26±0．08,焦点深度范围2．5D(+1．0D～-1．5D)。结论Acrysof ReSTOR可为患者提供良好的远、近视力,降低白内障患者术后对眼镜的依赖。手术效果满意,是一种较为理想的人工晶状体。(眼科,2006,15：344-347)Objective To evaluate the visual outcomes, depth of focus and safety after implantation of the Acrysof ReSTOR and the Acrysof Natural. Design Nonrandomized clinical trial. Participant 53 patients with age-related cataract （61 eyes ）were divided into two groups： Acrysof ReSTOR group（MIOL） included 28 patients （31 eyes）, and reference group-Acrysof Natural group（SIOL） included 25 patients （30 eyes）. Method All patients underwent phacoemulsification and IOL implantation. At 1 week, 1 month and 3 months postoperatively, distant and near visual acuities were observed, and depth of focus was measured 3 months postoperatively. Main Outcome Measure Uncorrected distant visual acuity （UCDVA）, uncorrected near visual acuity （UCNVA）, best corrected distant visual acuity（BCDVA）, best corrected near visual acuity（BCNVA）, distant corrected near visual acuity（DCNVA）, depth of focus. Result At 3 months postoperatively, in MIOL group： UCDVA was 0.90±0.15, UCNVA was 0.70±0.19, DCNVA was 0.73±0.21 and depth of focus was 5.5D （＋1.5--4.0D）, while in SIOL group： UCDVA was 0.84±0.14, UCNVA was 0.36±0.10, DCNVA was 0.26±0.08 and depth of focus was 2.5D （＋1.0--1.5D）. In MIOL group, UCDVA and UCNVA at 1 month were markedly better than those at 1 week. Conclusion Acrysof ReSTOR can provide excellent outcomes both in distants and near visions and it may reduce the dependence on spectacles in near vision.
