To evaluate the agreement in biometry measurements and intraocular lens (IOL) power calculations between 2 integrated swept-source optical coherence tomography (SS-OCT) tomography/biometry devices: the Eyestar 900 and the Anterion.

Retrospective comparative study.
113 eyes of 66 consecutive patients who were evaluated prior to cataract surgery using both devices on the same visit were included. Measurements of axial length, anterior and posterior keratometry, anterior chamber depth, corneal diameter (CD), central corneal thickness, and lens thickness were recorded from both devices and analyzed for agreement and correlation. IOL power calculations using Barrett Universal II formula were compared between the devices in addition to prediction error (PE) and the mean absolute error (MAE).
The mean age was 71.6 ± 9.8 years. Clinically, the mean differences in measured variables were small. Measurement correlation and agreement between the devices were excellent for all variables, except for CD (Spearman r = 0.763, P < .001, and Bland-Altman 95% limits of agreement -0.21 to +0.65 mm). Good agreement was found between the devices in IOL power calculations, PE, and MAE, and the agreement was better when using the Eyestar 900 reflective keratometry measurements than the Eyestar 900 SS-OCT keratometry measurements (IOL power agreement within ±0.5 diopter (D) in 90.5% [n = 95] and 81.0% [n = 85], respectively [ P = .076], and within ±0.25 D in 64.8% [n = 68] and 44.8% [n = 47], respectively [ P = .005]).
The 2 integrated SS-OCT tomography/biometry devices had good agreement in biometry measurements and IOL power calculations. Agreement was better when the Eyestar 900 reflective anterior keratometry measurements were used rather than the Eyestar 900 SS-OCT anterior keratometry measurements. Measurements of CD had reduced agreement and were not interchangeable.

回顾性比较研究。
纳入 66 例连续患者的 113 只眼，这些患者在白内障手术前使用这两种设备在同一次就诊中进行了评估。记录来自两种设备的眼轴长度、前/后角膜曲率、前房深度、角膜直径（CD）、中央角膜厚度和晶状体厚度，并分析其一致性和相关性。比较两种设备使用 Barrett 通用 II 公式的 IOL 计算结果，以及预测误差（PE）和平均绝对误差（MAE）。
平均年龄为 71.6±9.8 岁。临床测量方面，各变量的平均差异较小。除 CD 外，两种设备的测量相关性和一致性均良好（Spearman r=0.763，P <.001，Bland-Altman 95%一致性界限为-0.21 至+0.65mm）。两种设备的 IOL 计算、PE 和 MAE 结果一致性良好，且使用 Eyestar 900 反射性角膜曲率测量值的一致性优于使用 Eyestar 900 SS-OCT 角膜曲率测量值（IOL 计算值在±0.5 屈光度（D）内的一致性为 90.5%[n=95]和 81.0%[n=85]，P=0.076；在±0.25D 内的一致性为 64.8%[n=68]和 44.8%[n=47]，P=0.005）。
2 种集成的 SS-OCT 断层/生物测量仪在生物测量和 IOL 计算中具有良好的一致性。当使用 Eyestar 900 反射性前角膜曲率测量值而不是 Eyestar 900 SS-OCT 前角膜曲率测量值时，一致性更好。CD 的测量值一致性较差，不能互换。
