摘　　要：目的:评价超声乳化白内障吸除(PEA)联合A crySof Toric人工晶状体(IOL)植入术后1a A crySof Toric IOL矫正角膜散光的有效性、稳定性。方法:植入A crySof ToricIOL的白内障患者13例13眼,术前角膜规则性散光≥0.75D,术后1a检查裸眼视力、柱镜度数、角膜曲率、散瞳记录IOL轴向。结果:裸眼视力:术前<0.1为4眼,0.1～0.3为8眼,0.4～0.6为1眼;术后0.7～0.9为7眼,≥1.0为6眼;术前术后比较差异有统计学意义;术前柱镜度:-1.97±0.73(-3.5～1.25)D,术后柱镜度:-0.44±0.45(-1.25～0)D,术前术后比较差异有统计学意义;术后1a,A crySof Toric IOL平均旋转度为4.07°±3.07°(0°～10°),所有IOL的旋转均小于10°。结论:A crySof Toric IOL在植入术后1a,仍能稳定的矫正患者的角膜散光,使患者拥有较好的裸眼视力。AIM：To evaluate the efficacy and stability of AcrySof Toric intraocular les （IOL） to correct residual astigmatism in patients after one year from phacoemulsification cataract absorption（PEA） and AcrySof Toric IOL implantation. METHODS： This study included 13 eyes of 13 consecutive cataract patients with more than 0.75 diopter （D） of preexisting corneal astigmatism.1 year after IOL implantation, the uncorrected visual acuity（UCVA）,residual refractive cylinders, corneal keratometer,and AcrySof Toric IOL axis were measured. RESULTS： UCVA ：before operation presented0.1 in 4 eyes,0.1-0.3 in 8 eyes,0.4-0.6 in 1 eye,after operation,0.7-0.9 in 7 eyes,≥1.0 in 6 eyes. There was statistically significant difference between before operation and after [JP＋3]operation（P0.05）.The residual refractive cylinders was -1.97±0.73D（-3.5-1.25D） before operation and -0.44±0.45D（-1.25-0D） after operation.There was statistically significant difference between before operation and after operation（P0.05）.As for rotational stability,1 year after implantation, all AcrySof Toric IOL rotated less than 10 degrees.The mean AcrySof Toric IOL axis rotation was 4.07°±3.07°（0°-10°）. CONCLUSION： The AcrySof Toric IOL implantation is safe and effective to correct residual astigmatism in 1 year after cataract surgery.
