目的评价阶梯渐进衍射型多焦点人工晶状体(IOL)应用于近视患者的临床效果及安全性。设计前瞻性病例系列。研究对象近视合并白内障患者30例(44眼)。方法对以上患者行白内障超声乳化吸除术,按自愿原则分别植入Acrysof ReSTOR多焦点IOL14例(22眼)或普通单焦点IOL16例(22眼)。比较两组患者术后1周、1个月、3个月远、近视力及焦点深度范围。主要指标裸眼远近视力、矫正远近视力、最佳矫正远视力下近视力及焦点深度范围。结果阶梯渐进衍射型多焦点IOL组患者和单焦点IOL组患者的术后3个月平均裸眼远视力分别为0.84±0.14、0.70±0.23(P=0.018);平均裸眼近视力分别为0.69±0.34、0.32±0.13(P=0.000);矫正远视力下近视力分别为0.69±0.20、0.27±0.12(P=0.000);焦点深度范围分别为(5.54±0.53)D、(3.57±0.93)D(P=0.000)。结论近视患者植入阶梯渐进衍射型多焦点IOL可获得良好的远、近视力,效果满意。
Objective To evaluate the clinical effect and safety of using stepped progressive diffractive multifocal intraocular lens (IOL) in patients with myopia. Design prospective case series. The study included 30 patients (44 eyes) with myopia and cataract. Methods The above patients underwent cataract phacoemulsification. According to the voluntary principle, 14 cases (22 eyes) of Acrysof ReSTOR multifocal IOL or 16 cases (22 eyes) of normal single focus IOL were implanted. One week, one month and three months after operation were compared between the two groups. The range of near vision and depth of focus were compared. The main indicators of visual acuity far and near the naked eye, correction of near and far vision, the best correction of near vision and distance range of focal depth. Results The mean open vision (OCT) of the patients with step-shaped progressive multifocal IOL group and single-focal IOL group at 3 months after operation was 0.84 ± 0.14 and 0.70 ± 0.23 (P = 0.018), respectively. The mean open-hole myopia was 0.69 ± 0.34 , 0.32 ± 0.13 (P = 0.000). The corrected visual acuity was 0.69 ± 0.20,0.27 ± 0.12 (P = 0.000), and the depth of focus was (5.54 ± 0.53) D and (3.57 ± 0.93) D P = 0.000). Conclusion Myopia patients with graded progressive diffractive multifocal IOL can obtain good far and near vision, with satisfactory results.
