摘　　要：目的比较Tecnis Symfony连续视程人工晶状体(IOL)与SBL-3区域折射型多焦点人工晶状体(MIOL)植入术后的临床疗效。方法前瞻性病例对照研究。纳入2022年3~10月在安徽医科大学第一附属医院行超声乳化吸出联合IOL植入术的白内障患者37例(45只眼)。其中21例(25只眼)植入Symfony IOL为Symfony组,16例(20只眼)植入SBL-3为SBL-3组。比较两组术后3个月裸眼远、中、近距离视力、最佳矫正远视力(BCDVA)、客观散射指数(OSI)、调制传递函数截止频率(MTF cut off)、斯特尔比率(SR)、模拟对比度视力(PVA)、全眼总高阶像差(tHOAs)、球差(spherical)、彗差(coma)、三叶草差(trefoil)、二阶散光(secondastigmatism)、VF-14评分、近距离阅读脱镜率、夜间视觉干扰症状及疗效满意度。结果术后3个月,两组裸眼及BCDVA比较差异无统计学意义(P>0.05);Symfony组裸眼中视力优于SBL-3组,差异有统计学意义(P<0.05);SBL-3组裸眼近视力优于Symfony组,差异有统计学意义(P<0.001)。Symfony组OSI、MTF cut off、SR、OV100%、OV20%、OV9%均高于SBL-3组,差异均有统计学意义(P<0.001)。SBL-3组全眼总高阶像差、彗差、球差、三叶草、二阶散光均大于Symfony组,差异有统计学意义(P<0.05)。两组术后VF-14评分相比,差异有统计学意义(P<0.05);对于近距离阅读脱镜率、夜间视觉干扰症状及满意度,两组差异均无统计学意义(P>0.05)。结论两种IOL均可改善患者的术后视力及视觉质量,连续视程IOL可提供更高的中视力与更优秀的视觉质量,区域折射型MIOL的近视力更好。Objective To compare the clinical efficacy of Tecnis Symfony extended range of vision intraocular lens(IOL)and SBL-3 regional refractive multifocal IOL implantation.Methods A prospective cohort study was designed.45 eyes of 37 patients with cataract who underwent phacoemulsification and IOL implantation in the First Affiliated Hospital of Anhui Medical University from March to October 2022 were selected.Twenty-one patients(25 eyes)implanted with Symfony belonged to the Symfony group,and 16 patients(20 eyes)implanted with SBL-3 belonged to the SBL-3 group.The uncorrected distance,intermediate and near visual acuity,best corrected distance visual acuity,objective scatter index(OSI),modulation transfer function cut off frequency(MTF cut off),Sterr ratio(SR),simulated contrast visual acuity(PVA),high-order aberration,visual function index(VF-14),spectacle independence rate,night visual disturbance symptoms and efficacy satisfaction were investigated by questionnaire and were compared between the two groups at 3 months after the surgery.Results At 3 months after the operation,there was no significant difference in uncorrected and best corrected distance visual acuity between the two groups(P>0.05).The intermediate visual acuity in the Symfony group was better than that in the SBL-3 group(P<0.05).The near vision of the SBL-3 group was better than that of the Symfony group(P<0.001).The OSI,MTF cut off,SR,OV100%,OV20%,and OV9%of the Symfony group were higher than those in the SBL-3 group(P<0.001).The total higher-order aberrations,coma aberration,spherical aberration,trefoil aberration and second-order astigmatism in the SBL-3 group were greater than those in the Symfony group(P<0.05).There was significant difference in postoperative VF-14 score between the two groups(P<0.05).There were no significant differences between the two groups in the rate of spectacle independence,symptoms of night visual interference and satisfaction with near reading(P>0.05).Conclusions Both IOLs can improve the postoperative visual acuity and
