背景为了调查双侧序贯白内障手术后第二眼不同人工晶状体 (IOL) 屈光度计算公式中第二眼调整 (SEA) 方法的屈光结果。方法这项回顾性连续病例系列研究包括 234 名在医院环境中接受双侧序贯超声乳化术和 enVista MX60 植入的患者的 234 只眼睛。将采用 SEA 方法的标准公式（SRK/T 和 Barrett Universal II、BUII）计算的术后屈光结果与第二眼增强（SEE）方法下基于人工智能的 IOL 度数计算公式（PEARL DGS）计算的结果进行比较。确定±0.25屈光度(D)、±0.50 D、±0.75 D和±1.00 D范围内眼睛的中位绝对误差(MedAE)、平均绝对误差(MAE)和百分比预测误差(PE)。结果总体而言，SEA后MedAE的改善对于PEARL DGS (p< 0.01)、SRK/T (p< 0.001)是显着的和 BUII (p= 0.031)，在 PE ±0.50 D 范围内，眼睛的比例分别从 74.36、71.37 和 77.78% 增加到 83.33、80.34 和 79.49%。对于中等眼轴长度 (22–26mm) 的第一只眼睛，PEARL DGS with SEE 的 MedAE 最低 (0.21 D)。对于第一只眼 MAE 超过 0.50 D，SEA 方法使第二只眼显着改善 (p< 0.01)。眼间轴长度差异超过0.3mm与研究公式中SEA效果较弱相关（p> 0.05）。结论无论是采用SRK/T和BUII公式的SEA方法还是基于PEARL DGS公式的第二眼增强方法都可以改善第二眼的术后屈光结果。
BackgroundTo investigate the refractive outcomes of second‐eye adjustment (SEA) methods in different intraocular lens (IOL) power calculation formulas for second eye following bilateral sequential cataract surgery.MethodsThis retrospective consecutive case‐series study included 234 eyes from 234 patients who underwent bilateral sequential phacoemulsification and implantation of enVista MX60 in a hospital setting. Postoperative refraction outcomes calculated by standard formulas (SRK/T and Barrett Universal II, BUII) with SEA method were compared with those calculated by an artificial intelligence‐based IOL power calculation formula (PEARL DGS) under second eye enhancement (SEE) method. The median absolute error (MedAE), mean absolute error (MAE) and percentage prediction errors (PE) of eyes within ±0.25 diopters (D), ±0.50 D, ±0.75 D and ± 1.00 D were determined.ResultsOverall, the improvement in MedAE after SEA was significant for PEARL DGS (p< 0.01), SRK/T (p< 0.001) and BUII (p= 0.031), which increased from 74.36, 71.37, and 77.78% to 83.33, 80.34, and 79.49% of eyes within a PE of ±0.50 D, respectively. For first eyes with a medium axial length (22–26 mm), PEARL DGS with SEE had the lowest MedAE (0.21 D). For a first‐eye MAE over 0.50 D, SEA method led to significant improvement in the second eye (p< 0.01). Interocular axis length differences exceeding 0.3 mm were associated with weaker effects using SEA in the studied formulas (p> 0.05).ConclusionsEither SEA method with SRK/T and BUII formulas or second‐eye enhancement method based on the PEARL DGS formula can improve postoperative refractive outcomes in second eye.
