摘要
现代白内障手术已经转变成屈光性手术,因此安全有效地矫正散光是现代白内障手术的重要组成部分。Toric IOL(IOL)植入术因其高度的可预测性及安全性已经逐渐成为白内障术中矫正0.75D以上角膜规则散光的首选方式。Toric IOL需要植入在一个精准的轴位才能达到良好的散光矫正效果。Toric IOL错位的主要原因是术后旋转,这通常在术后不久发生。术后大幅度的旋转会降低Toric IOL的散光矫正效果,甚至在新的轴位上产生散光。术后IOL旋转的原因是多元化的,临床医生需要对此深入了解以最大幅度地减少旋转。大幅度旋转后的处理一般选择复位手术,手术时机的把握也尤为重要。本文就Toric IOL术后旋转的影响因素及处理原则进行综述。
Correcting astigmatism safely and effectively has become a crucial part of modern cataract surgery due to the transformation of the surgery into a refractive procedure. The increased predictability and enhanced safety of Toric intraocular lens(IOL) implantation has made it the preferred method of correcting corneal regular astigmatism above 0.75 D in cataract surgery. Toric IOL needs to be implanted in a precise axis position to achieve good astigmatism correction. A major cause of toric misalignment is postoperative rotation, which typically occurs soon after surgery. However, large axis misalignment will eliminate the astigmatism corrective effect of Toric IOL, even cause astigmatism in a new axis position. The factors responsible for IOL postoperative rotation are diverse. As a result, profound understanding of the factors is crucial for clinicians to minimize the rotation. Repositioning procedure is generally selected in case of significant rotation and the timing of the procedure is vital. This paper reviewed the influencing factors of IOL rotation postoperatively and its principle of treatment.
