【摘要】：目的观察白内障合并角膜散光患者植入Acrysof toric人工晶状体术后的视觉质量以及toric晶状体的眼内稳定性。 方法收集2009年10月至2010年9月在我院行白内障摘除联合Acrysof toric人工晶状体植入的患者60例80眼作为观察组,依据人工晶状体型号分为T3组,T4组,T5a组及T5b组,术后3个月观察患者的裸眼视力,最佳矫正视力,残余散光,对比敏感度,波前像差,晶状体的旋转度数、偏心值及倾斜度数。选取同期植入Acrysof Natural人工晶状体的患者45例75眼作为对照组。 结果术后3个月观察组70眼(87.5%)的UCVA≥0.5,对照组51眼(68%)的UCVA≥0.5,两组间比较差别有统计学意义(χ2=12.18,P0.05)；T3,T4,T5组术后视力均较术前改善,T5b组视力低于其余三组(χ2=20.37,P0.05)。观察组术后残余散光为(0.51±0.78)D,明显低于对照组(1.44±0.72)D(t=10.54,P0.05)；T5b组术后残余散光为(1.69±0.68)D,与T3,T4及T5a组比较均有统计学差异。观察组各个空间频率的对比敏感度均高于对照组,低阶像差及彗差低于对照组。T3,T4,T5a组对比敏感度高于T5b组,低阶像差及彗差低于T5b组。toric人工晶状体平均旋转(3.27±1.72)°,67眼(83.75%)旋转≤5°,79眼(98.75%)旋转≤10°；偏心值为(0.28±0.06)mm；倾斜度数为(2.08±0.14)。 结论Acrysof toric人工晶状体植入矫正散光疗效可靠,术后表现出良好的旋转及居中稳定性,患者获得较满意的视觉质量,是矫正白内障合并角膜散光的可靠的手术方式。
[Abstract]:Objective to observe the visual quality and intraocular stability of Acrysof toric intraocular lens (IOL) implantation in cataract patients with corneal astigmatism. Methods from October 2009 to September 2010, 60 patients (80 eyes) with cataract extraction and Acrysof toric intraocular lens implantation in our hospital were selected as observation group. According to the type of intraocular lens, they were divided into T3 group, T4 group, T5a group and T5b group. The uncorrected visual acuity, best corrected visual acuity, residual astigmatism, contrast sensitivity, wavefront aberration, rotation degree of lens, eccentricity and inclination were observed 3 months after operation. 45 patients (75 eyes) with Acrysof Natural intraocular lens implantation were selected as control group.
