摘　　要：目的:评价AcrySof Toric IOL在囊袋内的稳定性及矫正角膜散光的效果。方法:选择2010-04/2012-04在我院接受白内障超声乳化及AcrySof Toric IOL植入并且完成6mo随访的患者20例23眼。观察术前、术后裸眼视力(UCVA)、术前角膜散光、术后残余散光、IOL旋转度、晶状体偏中心情况、晶状体倾斜情况及囊袋情况。结果:术后6mo,100%患眼UCVA≥0.6,69.6%(16/23)患眼UCVA≥0.8。术前角膜散光平均为2.31±0.70D,术后6mo残余散光为0.45±0.30D,二者差异有统计学意义(t=15.045,P=0.000)。术后6mo时17眼(73.9%)偏离预定轴位,平均偏差5.36°±0.32°,其中2例偏差>10°,最大偏差15°;术后6mo时12眼(52.2%)出现晶状体偏中心,8眼(34.8%)<0.5mm,3眼(13.0%)为≥0.5mm而≤1mm,1眼(4.3%)>1mm;术后6mo时20眼(87.0%)晶状体无倾斜,3眼(13.0%)出现倾斜,倾斜均少于5°。结论:AcrySofToricIOL可使患者获得良好的裸眼远视力,有效的矫正患者的角膜散光,同时具有良好的位置稳定性,预测性强,是一种有效的矫正角膜规则散光的治疗方法。AIM：To evaluate the corneal astigmatism correction effect and positional stability of AcrySof Toric intraocular lens（IOL） after cataract surgery.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 6 months.The pre and post-operative uncorrected visual acuity（UCVA）,preoperative corneal astigmatism,postoperative residual astigmatism,Toric lens axis,Toric lens decentration,Toric lens tilt and the capsule were detected and measured.RESULTS：After 6 months,UCVA was ≥0.6 in 100% of eyes;≥0.8 in 69.6% of eyes.The mean preoperative corneal astigmatism was 2.31±0.70D and the postoperative residual astigmatism was 0.45±0.30D,indicating a significant decrease in refractive cylinder after surgery（t=15.045,P=0.000）.The mean rotation of Toric IOLs was 5.36°±0.32°.After 6 months,IOL centricity was in 12 eyes（52.2%） in which 8 eyes（34.8%）0.5mm,1mm3 eyes（13.0%）≥ 0.5mm,1 eye（4.3%）1mm.20 eyes（87.0%） was untilt while 3 eyes（13.0%） was tilt and less than 5°,CONCLUSION：Even in different orientation,AcrySof Toric IOL still has good position stability.It is an effective and predicted method for the correct of corneal astigmatism in cataract surgery.
