Cataract surgery has become a refractive procedure in which emmetropia is the goal, with the implantation of extended depth-of-focus or multifocal intraocular lenses (IOLs) being the commonly selected option to restore vision beyond the far distance. The selection criteria for implanting these lenses can differ from those for monofocal IOLs and even between technologies, as eye characteristics can affect postoperative visual performance. Corneal astigmatism is an eye characteristic that can affect visual performance differently, depending on the implanted IOL. The magnitude of corneal astigmatism, the tolerance of the IOL to this astigmatism, economic aspects, comorbidities, and the efficacy of astigmatism treatment are factors that can make surgeons' doubt as to what astigmatism treatment should be applied to each patient. This review aims to summarize the current evidence related to low astigmatism tolerance in presbyopia-correcting lenses, the efficacy achieved through corneal incisions, and their comparison with the implantation of toric IOLs.
白内障手术已成为屈光手术，正视是其目标，植入扩展景深或多焦点人工晶状体（IOL）是恢复远视视力的常用选择。这些镜片的植入选择标准可能与单焦点 IOL 不同，甚至在不同技术之间也不同，因为眼部特征会影响术后视觉表现。角膜散光作为一种眼部特征，根据植入的 IOL 不同，对视觉表现的影响也不同。角膜散光的程度、IOL 对此散光的容忍度、经济方面、合并症以及散光治疗的效果等因素，都会使外科医生怀疑应该为每位患者应用何种散光治疗。本综述旨在总结与矫正老视的低散光容忍度相关的当前证据、通过角膜切口获得的疗效，以及与植入散光 IOL 的比较。
