目的:探讨多焦点人工晶状体(Array)在白内障屈光手术中的作用。方法:回顾性研究行超声乳化白内障吸除术后植入多焦点人工晶状体(多焦组)19例25眼和植入单焦点人工晶状体(单焦组)14例20眼的患者术后30～52mo的不同对比度下中、近视力及相应戴镜率。结果:40cm距离100%对比度字母表:多焦组得分为54.64±10.80,单焦组得分为47.05±6.39,两组比较差异有统计学意义(t=2.93,P<0.05),40cm距离10%对比度字母表:多焦组得分为42.60±6.47,单焦组得分为34.55±5.86,两组比较差异有统计学意义(t=5.43,P<0.05),63,100cm距离不同对比度下两组比较,差异均无统计学意义(P>0.05)。近用多焦组有更高的脱镜率。结论:多焦点人工晶状体能为患者提供不同对比度下良好的视力。

AIM:To study the effects of multifocal intraocular lens implantation (MIOL) in cataract refrective surgery.METHODS:After small incision phacoemulsification,MIOL was inserted into the eyes of 19 cases (25 eyes),monofocal intraocular lens (SIOL) was inserted into the eyes of 14 cases (20 eyes).30-52 months after intraocular lens implantation,near visual acuity,intermediate visual acuity at different contrast and postoperative spectacle dependency were evaluated.RESULTS:At 40cm 100% contrast,MIOL got 54.64±10.80 scores and SIOL got 47.05±6.39 scores.There was statistically significant differences between MIOL and SIOL (P<0.05).At 40cm 10% contrast,MIOL got 42.60±6.47 scores and SIOL got 34.55±5.86 scores.There was statistically significant differences between MIOL and SIOL (P<0.05).Score of visual acuity at 63cm and 100cm at different contrast was no significantly statistical difference between two groups.Multifocal group of near use had a higher spectacle independence rate.CONCLUSION:MIOL provides a satisfactory vision at different contrast.
