目的 评价Toric人工晶状体(IOL)矫正角膜散光的效果及在囊袋内的稳定性.方法 白内障行超声乳化吸除联合Acrysof toric IOL植入37眼(治疗组),另外,对照组30眼,手术方式相同,术中植入SA60AT型IOL.观察术前、术后裸眼视力(UCVA)及最佳矫正视力(BCVA)、术前角膜散光、预计残余散光、术后残余散光、IOL旋转度,并进行分析.结果 治疗组术后3个月94.53％患眼UCVA≥0.5,81.07％患眼UCVA≥0.8,BCVA≥0.8者达96.92％.治疗组术前角膜散光平均为(1.82±0.87)D,术后3个月残余散光为(0.63±0.30)D,而对照组为(1.14±0.36)D,两组间差异有统计学意义.治疗组术后第1天IOL轴位偏离平均为(3.95±3.69)°,术后3个月平均偏离(2.52±1.95)°,94.60％患眼＜5°.结论 Toric IOL可使患眼获得更好的裸眼远视力,减少了患眼的残余散光,预测性强,具有良好的旋转稳定性,是一种有效的矫正角膜规则散光的治疗方法.

Objective To evaluate the effectiveness and rotational stability of Toric IOL to correct preexisting corneal astigmatism in cataract patients.Methods This Study included 37 eyes of 32 patients who underwent phacoemulsification and foldable Acrysoftoric IOL implantation from July 2008 to December 2009.As a comparison,30 eyes of 26 patients meeting the same preoperative criteria for degree of corneal cylinder were enrolled to have a Spherical (nontoric) IOL implanted.The uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA),preoperative corneal astigmatism,anticipated residual astigmatism,postoperative residual astigmatism and Toric IOL axis for both study and control groups were analyzed respectively.Results In the study group,94.53％ of eyes were 0.5 or better in UCVA in 3 months after the surgery,81.07％ of eyes were 0.8 or better in UCVA and 96.92％ of eyes were 0.8 or better in BCVA.In the study group,the mean preoperative corneal astigmatism was ( 1.82 ± 0.87 ) D and the postoperative refractive cylinder was (0.63 ± 0.30) D.As a comparison,the mean postoperative refractive cylinder of the control group was (1.14 ± 0.36) D.The difference between these two groups provides a sample base for statistics analysis.The mean deviation between the actual axis and anticipated axis of study group was (3.95±3.69) degrees 1 day after operation,and (2.52 ± 1.95 ) degrees 3 months after operation.94.60％ ＜ 5degree.Conclusion Toric IOL provides cataract patients better UCVA,good rotational stability and reduce the residual astigmatism.Toric IOL implantation is an effective,safe and predictable method to correct the preexisting corneal astigmatism in cataract surgery.
