To evaluate the performance of a new swept source optical coherence tomography optical biometer, ANTERION, in ocular biometry and intraocular lens (IOL) calculation compared with the reference standard of Dual Scheimpflug Analyzer (GALILEI, G6). A prospective comparative study was conducted in a tertiary eye center. Cataract patients were scanned with both devices in a random fashion, and parameters from the devices were analyzed in terms of mean difference and intraclass correlation coefficient (ICC). Bland-Altman plots were performed to compare agreement between the devices. Ninety-six eyes from 96 patients were enrolled for evaluation. With the exception of ACD, all parameters were significantly different, but excellent agreement was revealed for all of them. The mean difference in axial length was 0.03 mm, and ICC was 0.999. Calculated IOL power with Barrett formula revealed that 93.75% were within 1 diopter and the prediction error was 0.03 diopter. Biometry of the devices were arithmetically different. However, the mean difference of the key factors in IOL calculation were small and appeared to be negligible for the purposes of clinical application. The performance of ANTERION was comparable to that of G6 in biometric measurement and IOL calculation; however, the devices cannot be used interchangeably.
为了评估新型 swept source 光学相干断层扫描光学生物测量仪 ANTERION 在眼生物测量和人工晶状体 (IOL) 计算方面的性能，与 Dual Scheimpflug 分析器 (GALILEI，G6) 的参考标准进行比较。在一家三级眼科中心进行了前瞻性的比较研究。以随机的方式用两种设备对白内障患者进行扫描，并根据平均值差异和组内相关系数 (ICC) 分析设备参数。进行 Bland-Altman 图以比较两种设备之间的一致性。96 名患者的 96 只眼被纳入评估。除 ACD 外，所有参数均有显著差异，但所有参数的一致性均较好。眼轴长度的平均差异为 0.03mm，ICC 为 0.999。用 Barrett 公式计算的人工晶状体屈光度显示，93.75%在 1 屈光度以内，预测误差为 0.03 屈光度。两种设备的生物测量值在算法上有所不同。然而，IOL 计算中关键因素的平均差异较小，在临床应用中似乎可以忽略不计。ANTERION 的性能在生物测量和 IOL 计算方面与 G6 相当；然而，这两种设备不能互换使用。
