目的:在手术前存在角膜散光的患者中应用Toric IOL,报告初步的观察结果。方法:选择2008-06/2009-01在我院接受白内障超声乳化摘除及Toric IOL植入并且完成6mo随访的患者39例45眼,分别植入SN60-T3,T4,T5AcrysofToric IOL,术后6mo时比较术前、术后的屈光结果。结果:术后6mo时T3,T4,T5各组的未矫正视力分别为0.73±0.20,0.92±0.16,0.85±0.23,残余散光为-0.52±0.22D,平均轴位发生偏转为3.5±2.1度,各组分别为2.8±2.0,3.0±2.2,3.9±1.8度。结论:AcrysofToricIOL在矫正术前角膜散光方面是很有价值的。

·AIM:To evaluate astigmatism correction of the AcrySof Toric intraocular lens(IOL)in cataract patients.·METHODS:Thirty-nine patients 45 eyes were implanted with the AcrySof Toric IOL by the same surgeon between June 2008 and January 2009.Three Toric models were evaluated in cylinder powers of 1.50 diopters(D)(SN60-T3;T3 group,n=11),2.25D(SN60-T4;T4 group,n=17),and 3.00 D(SN60-T5;T5 group,n=17)at the IOL plane.The patients were followed up for 6 months with pre-and postoperatively refractive assessments performed.·RESULTS:Six months postoperatively,the mean un-corrected visual acuity(UCVA)was 0.73±0.20 in the T3 group,0.92±0.16 in the T4 group,0.85±0.23 in the T5 group,respectively.Residual astigmatism was-0.52±0.22D.The mean IOL rotation was 3.5±2.1degrees,2.8±2.0 in the T3 group,3.0±2.2 in the T4 group,3.9±1.8 in the T5 group,respectively.·CONCLUSION:Implantation of the AcrySof Toric IOL proved to be successful in correcting corneal astigmatism in cataract patients.·
