Abstract

Purpose: To compare the accuracy of 14 formulas in calculating intraocular lens (IOL) power in extremely long eyes with axial length (AL) over 30.0 mm.

Methods: In this retrospective study, 211 eyes (211 patients) with ALs > 30.0 mm were successfully treated with cataract surgery without complications. Ocular biometric parameters were obtained from IOLMaster 700. Fourteen formulas were evaluated using the optimized A constants: Barrett Universal II (BUII), Kane, Emmetropia Verifying Optical (EVO) 2.0, PEARL-DGS, T2, SRK/T, Holladay 1, Holladay 2, Haigis and Wang-Koch AL adjusted formulas (SRK/T_modified-W/K, Holladay 1_modified-W/K, Holladay 1_{NP-modified-W/K}, Holladay 2_modified-W/K, Holladay 2_{NP-modified-W/K}). The mean prediction error (PE) and standard deviation (SD), mean absolute errors (MAE), median absolute errors (MedAE), and the percentage of prediction errors (PEs) within ± 0.25 D, ± 0.50 D, ± 1.00 D were analyzed.

Results: The Kane formula had the smallest MAE (0.43 D) and MedAE (0.34 D). The highest percentage of PE within ± 0.25 D was for EVO 2.0 (37.91%) and the Holladay 1_{NP-modified-W/K} formulas (37.91%). The Kane formula had the highest percentage of PEs in the range of ± 0.50, ± 0.75, ± 1.00, and ± 2.00 D. There was no significant difference in PEs within ± 0.25, ± 0.50 ± 0.75 and ± 1.00 D between BUII, Kane, EVO 2.0 and Wang-Koch AL adjusted formulas (P > .05) by using Cochran's Q test. The Holladay 2_modified-W/K formula has the lowest percentage of hyperopic outcomes (29.38%).

Conclusions: The BUII, Kane, EVO 2.0 and Wang-Koch AL adjusted formulas have comparable accuracy for IOL power calculation in eyes with ALs > 30.0 mm.

14 种眼球内透镜功率计算公式在超长眼球中的准确性。

目的：比较 14 种公式在计算轴长（AL）超过 30.0 mm 的超长眼人工晶体（IOL）功率时的准确性：在这项回顾性研究中，有 211 只眼球（211 名患者）的轴长超过 30.0 毫米，并成功接受了白内障手术治疗，未出现并发症。眼部生物测量参数来自 IOLMaster 700。使用优化的 A 常数对 14 种公式进行了评估：巴雷特通用 II (BUII)、凯恩、Emmetropia Verifying Optical (EVO) 2.0、PEARL-DGS、T2、SRK/T、好莱迪 1、好莱迪 2、Haigis 和 Wang-Koch AL 调整公式（SRK/T 修正-W/K、好莱迪 1 修正-W/K、好莱迪 1NP 修正-W/K、好莱迪 2 修正-W/K、好莱迪 2NP 修正-W/K）。对平均预测误差（PE）和标准差（SD）、平均绝对误差（MAE）、中位数绝对误差（MedAE）以及预测误差（PE）在± 0.25 D、± 0.50 D、± 1.00 D以内的百分比进行了分析：凯恩公式的 MAE（0.43 D）和 MedAE（0.34 D）最小。EVO 2.0（37.91%）和好利得 1NP 改良-W/K 配方（37.91%）的 PE 在 ± 0.25 D 以内的比例最高。通过 Cochran's Q 检验，BUII、Kane、EVO 2.0 和 Wang-Koch AL 调整配方之间在 ± 0.25、± 0.50 ± 0.75 和 ± 1.00 D 范围内的 PE 百分比没有显著差异（P > .05）。霍拉迪 2 改良-W/K公式的远视结果比例最低（29.38%）：结论：BUII、Kane、EVO 2.0和Wang-Koch AL调整公式在计算AL大于30.0 mm的眼睛的人工晶体功率时具有可比的准确性。
