摘　　要：目的：评价AcrySof Toric人工晶状体（intraocular lens,IOL）植入矫正伴有规则性角膜散光白内障患者的临床效果及IOL的旋转稳定性。方法：随机选取南京医科大学第一附属医院眼科2012-06/2013-12的白内障合并规则角膜源性散光患者23例28眼行超声乳化白内障摘除联合AcrySof Toric IOL植入术者,观察术后裸眼视力（UCVA）,最佳矫正视力（BCVA）,以及统计术前预期残余散光与术后实际残余散光,Toric IOL在囊袋内的旋转度。结果：术后3mo UCVA为0.75±0.16,BCVA为0.84±0.15,BVCA与UCVA比较差异无统计学意义（t=1.036,P〉0.05）。术前预期残余散光为0.28±0.12D,术后3mo实际残余散光为0.42±0.17D,预期散光值与实际残余散光值比较,差异无统计学差异（t=1.259,P〉0.05）;Toric IOL术后1d IOL平均旋转3.02°±1.56°（0°～7°）,术后3mo平均旋转3.28°±1.85°（0°～7°）,其中25眼（89%）旋转〈5°,3眼（11%）旋转5°～7°。结论：Toric IOL植入能够稳定并且有效地矫正白内障患者的角膜散光,并有较精准的散光矫正预测性。AIM： To evaluate the clinical effect and the rotational stability of AcrySof Toric intraocular lens（ IOL）implantation to correct preexisting corneal astigmatism in cataract surgery. METHODS： Twenty- three patients（28 eyes） were enrolled from the department of ophthalmology in the first Affiliated Hospital of Nanjing Medical University. All patients underwent similar phacoemulsification procedure combined with AcrySof Toric IOL implantation from June 2012 to December 2013. The uncorrected visual acuity（ UCVA）, best corrected visual acuity（ BCVA）,anticipated residual astigmatism,postoperative residual astigmatism, and Toric IOL axis were detected and measured.RESULTS： Three months after operation,the UCVA of all eyes w ere 0. 75 ± 0. 16 and the BCVA w ere 0. 84 ±0. 15, there w as no significant difference betw een UCVA and BCVA（ t = 1. 036,P〈0. 05）. The anticipated residual astigm atism w as（ 0. 28 ± 0. 12） D. The actual residual astigm atism after 3m o of the operation w as（0. 42 ± 0. 17） D. There was no significant difference betw een anticipated and actual residual astigm atism（ t= 1. 259,P〈0. 05）. The m ean axis rotation of Toric IOL w as 3. 02° ± 1. 56°（0°- 7°） after 1d of operation and 3.28° ± 1. 85°（0°- 7°） after 3m o. Am ong all the eyes,25eyes（89%） rotated 5°,in 3 eyes（11%） rotated 5°-7°. CONCLUSION： The AcrySof Toric IOL implantation shows good effectiveness,predictability and stability in correcting pre- existing astigmatism in cataract patients.
