摘　　要：白内障摘除术后可因手术切口导致术源性散光(SIA)的出现, 特别是采用透明角膜切口的术式, 多可导致不同程度的角膜散光, 影响术后视觉质量。如何控制SIA并提高对SIA计算的精确性, 对指导手术前规划具有重要价值。本文就近年来国内外关于白内障摘除手术所导致的SIA的成因及其计算方法的研究进展进行综述, 以期为精准屈光性白内障摘除手术的开展奠定重要基础。After cataract extraction,surgically induced astigmatism(SIA)may occur due to the surgical incisions,especially when using clear corneal incisions,which may lead to different degrees of corneal astigmatism and affect postoperative visual quality.How to control SIA and improve the accuracy of SIA calculation is of great value to guide preoperative planning.In this article,the etiology and calculation methodologies of SIA in cataract surgery were reviewed,aiming to provide a reference for the clinical diagnosis and treatment of cataract refractive surgery.
