To assess the agreement between 2 swept-source optical coherence tomography biometry devices, Anterion and IOLMaster 700.
Tertiary referral center, Brisbane, Australia.
Prospective comparative study.
Bland-Altman analysis was used to assess agreement between devices for flat (K1), steep (K2), and mean (Km) keratometry for anterior, posterior, and total cornea, lens thickness (LT), anterior chamber depth (ACD), central corneal thickness (CCT), white to white (WTW), and axial length (AL). Generalized estimating equations were used to control for within-patient between-eye correlations. Interdevice differences were considered clinically significant if they were likely to alter the spherical refractive outcome by 0.25 diopter (D) or more.
159 eyes of 91 patients (41 male, 50 female) were included. Statistically significant differences were found for K1, K2, and Km for anterior, posterior, and total cornea. When the Anterion was compared with the IOLMaster 700, the mean differences were as follows: anterior K1: -0.17 D, anterior K2: -0.18 D, anterior Km: -0.17 D, posterior K1: -0.38 D, posterior K2: -0.36 D, posterior Km: -0.37 D, total K1: -0.65 D, total K2: -0.82 D, and total Km: -0.74 D. The difference in posterior and total K metrics was clinically significant. Statistically significant differences were noted for LT: 0.159 mm, CCT: -0.004 mm, ACD: 0.054 mm, and WTW: -0.152 mm, although these were not found to be clinically significant. There was no significant difference between devices for AL.
This study found statistically and clinically significant differences for both posterior and total keratometry between the Anterion and the IOLMaster 700. Posterior and total corneal parameters cannot be considered interchangeable between devices.

前瞻性比较研究。
采用 Bland-Altman 分析法评估两种设备在前、后和全角膜的平坦（K1）、陡峭（K2）和平均（Km）角膜曲率、晶状体厚度（LT）、前房深度（ACD）、中央角膜厚度（CCT）、白到白（WTW）和眼轴（AL）方面的差异。采用广义估计方程控制患者内双眼间的相关性。如果两种设备之间的差异可能导致球镜屈光结果改变 0.25 屈光度（D）或更多，则认为具有临床意义。
共纳入 91 例患者（41 名男性，50 名女性）的 159 只眼。在前、后和全角膜的 K1、K2 和 Km 方面均发现有统计学显著差异。与 IOLMaster 700 相比，Anterion 的平均差异如下：前 K1：-0.17 D，前 K2：-0.18 D，前 Km：-0.17 D，后 K1：-0.38 D，后 K2：-0.36 D，后 Km：-0.37 D，总 K1：-0.65 D，总 K2：-0.82 D，总 Km：-0.74 D。后角膜和总角膜 K 指标的差异具有临床意义。LT：0.159 mm、CCT：-0.004 mm、ACD：0.054 mm 和 WTW：-0.152 mm 存在统计学显著差异，但不具有临床意义。两种设备的 AL 之间无显著差异。
本研究发现 Anterion 和 IOLMaster 700 之间在后部和总角膜屈光度方面存在统计学和临床显著差异。两种设备的后部和总角膜参数不能相互替换。
