Toric IOL矫正角膜散光效果的影响因素分析

Analysis of factors influencing the effect of Toric intraocular lens on corneal astigmatism

白内障超声乳化联合人工晶状体(IOL)植入术是目前治疗白内障的有效方法之一,随着白内障手术技术的发展,传统白内障手术已从复明手术逐渐转变为屈光手术。散光矫正型人工晶状体(Toric IOL)的临床应用有效减小了患者的角膜散光,改善了患者的术后视觉效果。Toric IOL的矫正效果受多元因素的共同作用,包括术前生物测量的准确性,个体化选择合适的Toric IOL计算公式,植入轴位的精确度,手术切口的设计以及Toric IOL的旋转稳定性等。文章将对影响Toric IOL矫正角膜散光效果的因素做一综述。

Phacoemulsification combined with intraocular lens(IOL)implantation is currently one of effective methods for treating cataracts.As cataract surgery technology has evolved,traditional cataract surgery has shifted from vision surgery to refractive surgery.The Toric IOL can significantly reduce corneal astigmatism and enhance patients’postoperative visual effects.However,the corrective impact of Toric IOL is influenced by numerous factors,including the accuracy of preoperative biometric measurements,selection of appropriate Toric IOL calculation formulas,the precision of implantation axis,surgical incision design,and rotational stability of the Toric IOL.This article will review the factors that influence the Toric IOL’s effect on corneal astigmatism.
