Although error in refraction measurement with both machines and phoropters has long been recognized,1–3 study of its effects on observed cylinder change was generally ignored until a study by Bullimore et al.,4 which showed that the Correction Index will be much higher than 1 for low levels of cylinder correction because of refraction measurement error. In this study, we build off of that work to answer two key questions raised in their study: first, what is an appropriate measure for cylinder treatment success for cases where preoperative cylinder is 1.00 diopters (D) or less, which is a

将屈光度测量误差纳入角膜消融手术的手术计划中，比较展平和矫正指标

尽管人们早已认识到使用机器和屈光屈光度计进行屈光度测量的误差，但在Bullimore等人[4]的一项研究表明校正指数将比1由于折射测量误差而导致的低水平圆柱校正。在这项研究中，我们以这项工作为基础，回答了他们研究中提出的两个关键问题：首先，对于术前眼压等于或小于1.00屈光度（D）的病例，什么是成功治疗眼压的合适措施？
