To evaluate the level of agreement between ANTERION (Heidelberg Engineering, Heidelberg, Germany), OA-2000 (Tomey, Nagoya, Japan), and IOLMaster 500 (Carl Zeiss AG, Jena, Germany).
Fifty-one eyes of 51 patients were included in the study. Flat keratometry (K) and steep K, vector component of astigmatism (Jackson cross-cylinder at 0° and 90° [J0] and Jackson cross-cylinder at 45° and 135° [J45]), anterior chamber depth, and axial length were compared using the three devices. Repeated measures analysis of variance was conducted to compare the mean values of the biometrics. Pearson correlation test was conducted to analyze the correlations of the measured values, and a Bland-Altman plot was used to assess the agreement between the three devices. The predicted intraocular lens power of each device was compared to the others using the SRK/T, Haigis, Barrett Universal II, and Kane formulas.
All K values measured using ANTERION were flatter than those of other instruments. However, good agreement was observed for flat K (ANTERION - OA-2000; 95% limits of agreement [LoA], 0.86 diopters [D]) and steep K (ANTERION - OA2000; 95% LoA, 0.93 D) and OA-2000 - IOLMaster 500 (95% LoA, 0.93 D). J0 and J45 vector components of astigmatism were not statistically different; however, the agreements were poor between the devices (95% LoA ≥1.97 D). Anterior chamber depth values of ANTERION and OA-2000 were interchangeable (95% LoA, 0.15 mm). The axial length showed a high agreement (95% LoA ≤0.17 mm) among the three devices. The predicted intraocular lens powers of the three devices were not interchangeable regardless of formulas (95% LoA ≥1.04 D).
Significant differences in ocular biometrics were observed between ANTERION and the other two devices. This study demonstrated that only axial length showed good agreement among devices.
评估 ANTERION（德国海德堡工程公司）、OA-2000（日本富美来）和 IOLMaster 500（德国卡尔蔡司公司）之间的一致性水平。
本研究纳入了 51 例 51 只眼。使用这三种设备比较了平 K 值和陡 K 值、散光矢量分量（0°和 90°的 Jackson 交叉圆柱镜[J0]和 45°和 135°的 Jackson 交叉圆柱镜[J45]）、前房深度和眼轴长度。采用重复测量方差分析比较生物测量的平均值。采用 Pearson 相关分析评估测量值的相关性，并采用 Bland-Altman 图评估三种设备之间的一致性。使用 SRK/T、Haigis、Barrett Universal II 和 Kane 公式比较每种设备的预测人工晶状体度数与其他设备的预测值。
使用 ANTERION 测量的所有 K 值均比其他仪器平坦。然而，平 K（ANTERION-OA-2000；95%限差[LoA]，0.86 屈光度[D]）和陡 K（ANTERION-OA2000；95% LoA，0.93 D）以及 OA-2000-IOLMaster 500（95% LoA，0.93 D）之间观察到良好的一致性。J0 和 J45 散光矢量分量无统计学差异，但各仪器之间的一致性较差（95% LoA≥1.97 D）。ANTERION 和 OA-2000 的前房深度值可互换（95% LoA，0.15mm）。三种设备的眼轴长度具有高度一致性（95% LoA≤0.17mm）。无论公式如何，三种设备的预测人工晶状体度数均不可互换（95% LoA≥1.04 D）。
ANTERION 与其他两种设备的眼部生物测量值存在显著差异。本研究表明，只有眼轴长度在设备之间具有良好的一致性。
