摘　　要：目的比较2种多焦点人工晶状体IQReSTOR+3D和IQReSTOR+4D的临床效果。方法选择年龄相关性白内障患者32例(41眼)行白内障超声乳化吸除联合人工晶状体植入术,其中IQReSTOR+3D组15例(20眼),IQReSTOR+4D组17例(21眼),比较术后3个月2组患者的远距离、中距离和近距离视力、对比敏感度、视野、离焦曲线和生活问卷调查结果。结果术后3个月,IQReSTOR+3D组裸眼中距离视力为1.38±0.06,优于IQReSTOR+4D组(1.07±0.09),差异有统计学意义(P<0.05)。2组间近距离和远距离视力差异均无统计学意义(均为P>0.05)。离焦曲线IQReSTOR+3D组在-1.5D、-2.0D、-2.5D的视力均优于IQReSTOR+4D组,差异均有统计学意义(均为P<0.05)。结论 IQReSTOR+3D较IQReSTOR+4D能够提供更好的中距离视力和一定距离范围的近视力。Objective To compare the clinical effects after implantation of multifocal lens（MIOL） between IQ ReSTOR＋3 D and IQ ReSTOR＋4 D.Methods Random clinical study of 32 patients（41 eyes） age-related cataract patients underwent phacoemulsification and IOL implantation,15 patients（20 eyes） in IQ ReSTOR＋3 D group and 17 patients（21 eyes） in IQ ReSTOR＋4 D.At 3 months after cataract surgery,the distant,intermediate and near visual acuities,contrast sensitivity,visual fields,defocus testing and questionnaires in two groups were observed.Results At postoperative 3 months,the uncorrected intermediate visual acuity of IQ ReSTOR＋3 D group was 1.38±0.06,which was much better than that of IQ ReSTOR＋4 D group 1.07±0.09,there was statistical difference（P0.05）.There was no significant difference in near and distant visual acuity between two groups（all P0.05）.The defocus testing showed the visual acuity at-1.5 D,-2.0 D,-2.5 D in IQ ReSTOR＋3 D group were better than that of IQ ReSTOR＋4 D group,there were statistical differences（all P0.05）.Conclusion The diffractive multifocal IOL with a ＋3 D add power provides significantly better intermediate visual acuity and a plateau of optimum near vision than multifocal IOL with a ＋4 D add power.
