Abstract

PURPOSE

To compare the accuracy of new/updated methods of intraocular lens (IOL) power calculation (Kane, Hill-RBF 2.0, and Holladay 2 with new axial length adjustment) with that of established methods (Barrett Universal II, Olsen, Haigis, Holladay 1, Hoffer Q, and SRK/T).

SETTING

Bristol Eye Hospital, University Hospitals Bristol National Health Service, Foundation Trust, Bristol, UK.

DESIGN

Retrospective consecutive case series.

METHODS

Data from patients having uneventful cataract surgery with the insertion of 1 of 4 IOL types were included. Optimized IOL constants were used to calculate the predicted refraction of each formula for each patient. This was compared with the actual refractive outcome to give the prediction error. A subgroup analysis occurred based on the axial length and IOL type.

RESULTS

The study included 10 930 eyes of 10 930 patients with the Kane formula having the lowest mean absolute prediction error (MAE), which was statistically significant (P < .001 in all cases) followed by the Hill 2.0, Olsen, Holladay 2, Barrett Universal 2, Holladay 1, SRK/T, Haigis, and Hoffer Q formula. The percentage of eyes predicted within ±0.5 D was Kane, 72%; Hill 2.0, 71.2%; Olsen, 70.6%; Holladay 2, 71%; Barrett 2, 70.7%; SRK/T, 69.1%; Haigis, 69%; and Hoffer Q, 68.1%. The Kane formula had the lowest MAE for short, medium, and long axial length subgroups and for each IOL type assessed. The updated versions of the Holladay 2 and Hill 2.0 formulas have resulted in improved accuracy.

CONCLUSIONS

Overall and in each axial length subgroup, the Kane formula was more accurate than the other formulas.

摘要

目的

比较新/更新的眼内晶状体（IOL）屈光力计算方法（凯恩、Hill-RBF 2.0 和霍拉迪 2 型并带有新的眼轴调整）与已建立的方法（巴雷特通用 II、奥尔森、海吉斯、霍拉迪 1 型、霍弗 Q 和 SRK/T）的准确性。

地点

英国布里斯托尔大学医院布里斯托尔国民保健服务基金会信托基金会眼科医院。

设计

回顾性连续病例系列。

方法

纳入无并发症白内障手术且植入 4 种 IOL 类型之一的患者数据。为每位患者使用优化的 IOL 常数来计算每个公式的预测屈光度。将此预测值与实际屈光结果进行比较，得出预测误差。基于眼轴和 IOL 类型进行了亚组分析。

结果

该研究共纳入 10930 只眼 10930 例患者，其中凯恩公式的平均绝对预测误差（MAE）最低，统计学上具有显著性差异（所有情况下均 P <.001），其次是 Hill 2.0、奥尔森、霍拉迪 2 型、巴雷特通用 2 型、霍拉迪 1 型、SRK/T、海吉斯和霍弗 Q 公式。预测值在±0.5 D 内的眼数凯恩公式为 72%；Hill 2.0 公式为 71.2%；奥尔森公式为 70.6%；霍拉迪 2 型公式为 71%；巴雷特 2 型公式为 70.7%；SRK/T 公式为 69.1%；海吉斯公式为 69%；霍弗 Q 公式为 68.1%。凯恩公式在短、中、长眼轴亚组和评估的每种 IOL 类型中均具有最低的 MAE。霍拉迪 2 型和 Hill 2.0 公式的更新版本提高了准确性。
