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 clinical efficacy and safety of multifocal intraocular lens (IOL) in the treatment of phacoemulsification combined with Acrysof ReSTOR (multifocal intraocular lens implantation) and intraocular lens implantation (Acrysof Natural). Design non-randomized clinical trials. Subjects Fifty-one patients (61 eyes) with age-related cataract were divided into two groups according to the principle of voluntary choice: 28 cases (31 eyes) in multifocal intraocular lens group and 25 eyes (30 eyes) in single focal intraocular lens group (control group). Methods All patients underwent cataract phacoemulsification with different types of intraocular lens implantation. One week, one month and three months after operation, the eyes of far eyesight, near vision and depth of focus were observed. The main indicators of non-correction far, near vision, best correction far, near vision. Near vision correction of near vision, the depth of focus. Results In the multifocal intraocular lens group, the average distance of naked vision was 0.90 ± 0.15 at 3 months after operation, the average naked eye myopia was 0.70 ± 0.19 and the near vision corrected distance was 0.73 ± 0.21, Focus depth range 5.5D (+ 1.5D ~ -4.0D). At 1 month after operation, the naked eye was far and the near vision was significantly increased compared with that at 1 week (P = 0.001, P = 0.000). The average uncorrected distance vision was 0.84 ± 0.14 in three months after operation in the single focal intraocular lens (IOL) group, the average naked eye myopic power was 0.36 ± 0.10 and the near vision corrected myopia was 0.26 ± 0.08 Depth range of 2.5D (+ 1.0D ~ -1.5D). Conclusion Acrysof ReSTOR can provide patients with good far and near vision, reducing cataract patients after surgery dependent on the glasses. Satisfactory surgical results, is a more ideal intraocular lens. (Ophthalmology, 2006,15: 344-347)
