One of the greatest issues facing the cataract surgeon today is accurate prediction of post-operative refractive error. With use of intraoperative autorefractometry (IOAR), such errors can be detected and post-operative refractive errors avoided. An 83-year-old woman was admitted for right eye phacoemulsification, with aimed at -1.78D with Sanders/Retzlaff/Kraff/T (SRK/T) formula implantation under local anesthesia. IOAR was performed after IOL insertion. The first estimate was +1.1D, indicating hyperopia, and far from the desired refraction above 2D. IOL exchange to +11.5D was, therefore, performed. The second estimate was -0.13D and the operation was completed. The final refraction (3 years after operation) was -0.25D. With IOAR, we were able to avoid the unpleasant surprise of a mistaken intraocular lens power. Intraoperative autorefractometry is useful for avoiding errors in IOL power.
如今白内障手术医生面临的最大问题之一是准确预测术后屈光不正。通过使用术中自动验光（IOAR），可以检测到此类误差并避免术后屈光不正。一名83岁女性因右眼白内障超声乳化术入院，计划在局部麻醉下根据桑德斯/雷茨拉夫/克拉夫/T（SRK/T）公式植入人工晶状体，目标屈光度为-1.78D。人工晶状体植入后进行了IOAR。第一次测量结果为+1.1D，表明为远视，与期望的超过2D的屈光度相差甚远。因此，将人工晶状体更换为+11.5D。第二次测量结果为-0.13D，手术完成。最终屈光度数（术后3年）为-0.25D。通过IOAR，我们能够避免人工晶状体屈光度错误带来的不愉快意外。术中自动验光有助于避免人工晶状体屈光度误差。
