With progressively improving visual rehabilitation following cataract surgery, patient expectations of favorable refractive outcomes have increased, ultimately requiring accurate preoperative surgical planning.1 The innovation of intraocular lenses (IOLs) that take into account corneal morphology to correct for preoperative astigmatism has become an option in surgical assessments, but clear corneal incisions (CCIs) and their impact on corneal curvature may induce aberrant postoperative refractive results.2
There have been attempts to minimize surgically induced astigmatism (SIA) by a variety

随着白内障手术后视力恢复的逐步改善，患者对良好屈光效果的期望越来越高，最终需要准确的术前手术计划。1考虑角膜形态以校正术前散光的人工晶状体（IOL）的创新已成为一种选择。手术评估，但是清楚的角膜切口（CCI）及其对角膜曲率的影响可能会导致术后屈光异常。2
