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(IOL)后角膜散光矫正的效果及Toric IOL的眼内稳定性。方法:选择2010-04/2012-04在我院接受白内障超声乳化及Acrysof Toric IOL植入,并完成12mo随访的患者20例23眼。观察术前、术后裸眼视力(uncorrected visual acuity,UCVA),术前角膜散光,术后残余散光及IOL旋转度、偏中心、倾斜情况。结果:术后随访12mo,UCVA≥0.6者23眼(100%),UCVA≥0.8者17眼(74%);术前角膜散光平均为(2.31±0.70)D,术后残余散光为(0.43±0.28)D,两者差异有统计学意义(P=0.00)。17眼(74%)IOL旋转偏离预定轴位,平均旋转度数为4.98°±0.25°,其中2眼旋转>10°,最大旋转为12.9°;11眼(48%)IOL出现偏中心,7眼(30%)偏中心<0.5mm,0.5mm≤3眼(13%)≤1 mm,1眼(4%)偏离1.1 mm;20眼(87%)IOL无倾斜,3眼(13%)出现倾斜,倾斜度数均少于5°。结论:Acrysof Toric IOL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,远期患者依然获得满意的视觉质量,是矫正白内障合并角膜散光的可靠手术方式。AIM：To observe the visual quality and capsular stability after implantation ofAcrysof Toric intraocular lens （ IOL ） in cataract patients with corneal astigmatism. METHODS： Totally 20 patients 23 eyes were implanted with the Acrysof Toric IOL between April 2010 and April 2012.All the patients were followed up for 12 months.The pre and post -operative uncorrected visual acuity （ UCVA ） , preoperative corneal astigmatism, postoperative residual astigmatism, IOL axis, IOL decentration, IOL tilt and the capsule were detected and measured. RESULTS：After 12 months, UCVA was≥0.6 in 23 eyes （100%）;≥0.8 in 17 eyes （74%）.The mean preoperative corneal astigmatism was （ 2.31 ±0.70 ） D and the postoperative refractive cylinder was （ 0.43 ±0.28 ） D, which was statistically significance （P=0.00）.The mean rotation of Toric IOL in 17 eyes （74%） was （4.98±0.25）°, of which 2 cases＇rotation was 〉10°, the maximum was 12.9°.IOL decentration was in 11 eyes （48%） in which 7 eyes （30%） 〈0.5mm, 0.5mm≤3 eyes （13%） ≤1mm, 1 eye （4%）=1.1mm.20 eyes （87%） was not tilted while 3 eyes （13%） was tilted an less than 5°. CONCLUSION： Implantation of theAcrysof Toric IOL proves to be an effective, safe, and stable method of managing corneal astigmatism in cataract patients and provides patients with good visual quality.The Acrysof Toric IOL demonstrates excellent rotation and centration stability.
