PURPOSE To evaluate whether intraoperative aberrometry improves the accuracy of refractive outcomes after cataract surgery in highly myopic, highly hyperopic, and post-refractive eyes. METHODS This single-center, retrospective review compared the spherical equivalent of postoperative refraction to that predicted by the Barrett Universal II formula versus Optiwave Refractive Analysis (ORA) (Alcon Laboratories, Inc) for highly myopic and hyperopic eyes and to the Barrett True K formula versus ORA for post-refractive eyes. The number and magnitude of lens changes were analyzed and used to determine in how many cases refractive surprises were affected by ORA, with additional subanalysis of outcomes based on average keratometry values. RESULTS ORA led to a change in the lens power implanted in 48% (96 of 198) of eyes, and prevented hyperopic surprise in 27% (15 of 55) and excess myopia in 46% (19 of 41). Steeper keratometry values correlated with more frequent changes on ORA-recommended implanted intraocular lens (P = .0031). ORA led to a similar percentage of eyes falling within ±0.50, ±0.75, and ±1.00 diopters compared to the Barrett Universal II and Barrett True K formulas. In post-refractive eyes, ORA led to a similar mean absolute error when compared to the Barrett True K formula (P = .62). For highly myopic eyes with an axial length of greater than 27 mm, ORA demonstrated a trend toward lower mean absolute error when compared to the Barrett Universal II formula (P = .076). CONCLUSIONS ORA demonstrated similar refractive results to the Barrett True K formula in post-refractive eyes and to the Barrett Universal II formula in highly myopic and hyper-opic eyes and may provide additional benefit for eyes with steeper corneas or an axial length of greater than 27 mm.

使用术中像差测量高度近视、高度远视和屈光后眼的屈光结果。

目的 评估术中像差测量是否能提高高度近视、高度远视和屈光后眼白内障手术后屈光结果的准确性。方法 该单中心回顾性综述将术后屈光度的等效球面度数与 Barrett Universal II 公式与 Optiwave 屈光度分析 (ORA)（Alcon Laboratories, Inc）预测的高度近视和远视眼以及 Barrett True K 公式进行比较与用于屈光后眼睛的 ORA 相比。分析了镜片变化的数量和幅度，并用于确定在多少情况下屈光异常受 ORA 影响，并根据平均角膜曲率值对结果进行额外的子分析。结果 ORA 导致 48% (96 of 198) 眼植入的晶状体度数发生变化，并防止了 27%（55 人中的 15 人）的远视意外和 46%（41 人中的 19 人）的过度近视。更陡峭的角膜曲率值与 ORA 推荐的植入人工晶状体的更频繁变化相关 (P = .0031)。与 Barrett Universal II 和 Barrett True K 公式相比，ORA 导致类似百分比的眼睛落在 ±0.50、±0.75 和 ±1.00 屈光度内。在屈光后的眼睛中，与 Barrett True K 公式 (P = .62) 相比，ORA 导致了类似的平均绝对误差。对于轴长大于 27 毫米的高度近视眼，与 Barrett Universal II 公式相比，ORA 显示出平均绝对误差较低的趋势（P = .076）。结论 ORA 在屈光后眼中显示出与 Barrett True K 公式和在高度近视和远视眼中与 Barrett Universal II 公式相似的屈光结果，并且可能为角膜较陡或轴长大于 27 的眼睛提供额外的益处毫米。[J 屈光手术。2021;37(9):609-615.]。
