High levels of corneal astigmatism are prevalent in a significant proportion of the population. During cataract surgery pre-existing astigmatism can be corrected using single or paired incisions on the steep axis of the cornea, using relaxing incisions or with the use of a toric intraocular lens. This review provides an overview of the conventional methods of astigmatic correction during cataract surgery and in particular, discusses the various types of toric lenses presently available and the techniques used in determining the correct axis for the placement of such lenses. Furthermore, the potential causes of rotation in toric lenses are identified, along with techniques for assessing and quantifying the amount of rotation and subsequent management options for addressing post-operative rotation.
相当一部分人群中存在高水平的角膜散光。在白内障手术期间，可通过在角膜陡峭轴线上进行单切口或双切口、使用松解切口或植入散光人工晶状体来矫正术前存在的散光。本综述概述了白内障手术中散光矫正的传统方法，尤其讨论了目前可用的各类散光晶状体以及确定此类晶状体正确植入轴的技术。此外，还明确了散光晶状体旋转的潜在原因，以及评估和量化旋转量的技术，以及处理术后旋转的后续管理方案。
