摘　　要：目的　探讨多焦点人工晶状体植入术的临床疗效。方法　随机将 196例 (2 5 5只眼 )老年性白内障患者分为试验组 (12 1只眼 ,使用多焦点人工晶状体 )和对照组 (134只眼 ,使用单焦点人工晶状体 )行超声乳化白内障吸除人工晶状体植入术。检查患者术后的远、近视力 ,观察配镜情况、人工晶状体的位置及手术并发症的发生情况。随访时间 3个月至 1年。结果　术后 3个月 ,试验组裸眼远视力≥0 5者 10 7只眼 ,≥ 1 0者 2 7只眼 ,与对照组比较差异无显著意义 (P >0 0 5 ) ;试验组裸眼近视力≥ 0 5者 93只眼 ,≥ 1 0者 2 2只眼 ,试验组明显优于对照组 (P <0 0 1)。术后 1个月 ,试验组人工晶状体双襻位置不对称 6只眼 ,均未影响视力恢复 ;手术源性角膜散光度数为 0 31D。试验组双眼手术者中33 3%阅读时戴镜 ,对照组 90 0 %阅读时戴镜。两组术后视觉异常症状均不明显 ;术后晶状体后囊膜混浊试验组 6只眼 ,对照组 12只眼。结论　多焦点人工晶状体植入术不仅可使患者恢复良好的裸眼远视力 ,而且可使患者的裸眼近视力明显提高 ;手术安全、可靠 ,无特殊并发症。Objective To evaluate the visual outcome of Array IOL, and examine the location of the lens. Methods 255 eyes in 196 patients received phaco and IOL implantation were randomized as test group 121 eyes(Array IOL) and case control group 134 eyes (monofocal Hydroview IOL). Postoperative examination included distance and near, uncorrected and corrected visual acuity, refractive results, and measurement of corneal curvature. Follow-up period ranged from three months to one year. Results Three months after surgery, 97.2% eyes (107/110) in test group with Array IOL had a distance visual acuity ≥0.5, and in 24.5% (27/110) ≥1.0. The difference was not significant (P>0.05) . 84.6% eyes (93/110) in test group had an uncorrected near acuity ≥0.5 and 20.0% (22/110) ≥1.0. The difference was significant (P<0.01). The rate of wearing spectacles was 33.3% in test group and 90% in case control group. One month after surgery, 6 eyes in test group with haptic asymmetric location were not affected with visual recovery. The surgery-induced astigmatism in test group was 0.31 D, and no visual impairment appeared in both groups. Posterior capsule opacification was seen in 6 eyes in test group and 12 in case control group.Conclusion The implantation of Array IOL not only has a good distance uncorrected visual acuity, but also with better near visual acuity. Also this surgery is safe, reliable and no special complication-induced.
