摘　　要：Toric IOL植入是矫正白内障合并散光的一种方式,它的散光矫正效果依赖于实际轴位与目标植入轴位的对齐程度,旋转度数与散光和离焦像差的增加呈正相关。眼轴过长、撕囊不规整、前囊膜严重纤维化、IOL材料黏附性差、术后剧烈活动等均是Toric IOL发生旋转的危险因素。Toric IOL implantation is a way to correct cataract with astigmatism.The degree of rotation is positively correlated with the increase of astigmatism and defocus aberration.The rotation of the IOL will lead to different degrees of astigmatism and defocus aberration.Long axial length,irregular capsulorhexis,severe fibrosis of the anterior capsule membrane,poor adhesion of IOL materials,and postoperative vigorous activity are all risk factors for Toric IOL rotation.
