Abstract

PURPOSE

To investigate the accuracy of modern intraocular lens (IOL) power calculation formulas in eyes with axial length (AL) ≥ 26.00 mm.

METHODS

A total of 193 eyes with one type of lens were analysed. An IOL Master 700 (Carl Zeiss Meditec, Jena, Germany) was used for optical biometry. Thirteen formulas and their modifications were evaluated: Barrett Universal II, Haigis, Hoffer QST, Holladay 1 MWK, Holladay 1 NLR, Holladay 2 NLR, Kane, Naeser 2, SRK/T, SRK/T MWK, T2, VRF and VRF-G. The User Group for Laser Interference Biometry lens constants were used for IOL power calculation. The mean prediction error (PE) and its standard deviation (SD), the median absolute error (MedAE), the mean absolute error (MAE) and the percentage of eyes with PEs within ± 0.25 D, ± 0.50 D and < ± 1.00 D were calculated.

RESULTS

The modern formulas (Barrett Universal II, Hoffer QST, Kane, Naeser 2 and VRF-G) produced the smallest MedAE among all methods (0.30 D, 0.30 D, 0.30 D, 0.29 D and 0.28 D, respectively). The percentage of eyes with a PE within ± 0.50 D ranged from 67.48% to 74.85% for SRK/T and Hoffer QST, Naeser 2 and VRF-G, respectively.

CONCLUSIONS

Dunn's post hoc test of the absolute errors revealed statistically significant differences (P < 0.05) between some of the newer formulas (Naeser 2 and VRF-G) and the remaining ones. From a clinical perspective the Hoffer QST, Naeser 2 and VRF-G formulas were more accurate predictors of postoperative refraction with the largest proportion of eyes within ± 0.50 D.

摘要

目的

研究眼轴（AL）≥26.00mm 时，现代人工晶状体（IOL）计算公式的准确性。

方法

共分析了 193 只眼，使用 IOL Master 700（德国卡尔蔡司公司，耶拿）进行光学生物测量。评估了 13 种公式及其修正：Barrett Universal II、Hoffer QST、Holladay 1 MWK、Holladay 1 NLR、Holladay 2 NLR、Kane、Naeser 2、SRK/T、SRK/T MWK、T2、VRF 和 VRF-G。使用激光干涉生物测量仪的用户组常数进行 IOL 屈光力计算。计算平均预测误差（PE）及其标准差（SD）、中位数绝对误差（MedAE）、平均绝对误差（MAE）和预测误差在±0.25D、±0.50D 和<±1.00D 内的眼数百分比。

结果

现代公式（Barrett Universal II、Hoffer QST、Kane、Naeser 2 和 VRF-G）在所有方法中产生的 MedAE 最小（分别为 0.30D、0.30D、0.30D、0.29D 和 0.28D）。SRK/T 和 Hoffer QST、Naeser 2 和 VRF-G 的预测误差在±0.50D 内的眼数百分比分别为 67.48%和 74.85%。
