Abstract

Background: Advanced swept-source optical coherence tomography (SS-OCT) devices are the current gold standard for the measurement of ocular biometric and keratometric parameters, which are essential for the calculation and selection of intraocular lenses (IOLs). This study compares the agreement of two SS-OCT devices, the Eyestar 900 (Haag-Streit, Köniz, Switzerland) and the Anterion (Heidelberg Engineering, Heidelberg, Germany).

Materials and methods: All patients undergoing cataract surgery or seeking consultation for corneal abnormalities between January 2024 and May 2024 were eligible for inclusion. Both eyes were included in the final analysis.

Results: A sample of 86 eyes from 43 patients was analysed. The mean differences (ES-AN) across all data between the Eyestar 900 (ES) and Anterion (AN) were as follows: anterior chamber depth (ACD) - 0.080 mm (ICC > 0.926), axial length (AL) 0.015 mm (ICC > 0.99), central corneal thickness (CCT) 0.914 µm (ICC > 0.921), corneal curvature along the flat meridian (K1) - 0.024 D (ICC > 0.904), and steep meridian (K2) - 0.210 D (ICC > 0.902), white-to-white corneal diameter (WTW) 0.215 mm (ICC > 0.81). There was excellent agreement for ACD, AL, CCT, K1, K2, and WTW. However, the corneal axis (AX) showed only moderate agreement (ICC > 0.389), with a mean difference of 5.97° and a notable standard deviation of 58.6°.

Conclusions: The Eyestar 900 and Anterion demonstrated substantial agreement for all parameters except for the corneal meridian axis. It may be assumed that the inclusion of eyes with irregular corneal topographies may have contributed to this discrepancy.

Summary: Overall, there was a high level of agreement between the Eyestar 900 and Anterion. It is reasonable to assume that the measurement outcomes provided by both devices are interchangeable for the calculation of target refractive outcomes for intraocular lenses, with no clinically relevant differences.

两种扫描源OCT设备眼部生物测量的比较：Eyestar 900和Anterion。

背景：先进的扫描源光学相干断层扫描（SS-OCT）设备是目前测量眼部生物特征和角膜测量参数的金标准，这些参数对人工晶体（iol）的计算和选择至关重要。本研究比较了两种SS-OCT设备的一致性，Eyestar 900 （Haag-Streit, Köniz，瑞士）和Anterion （Heidelberg Engineering, Heidelberg，德国）。材料和方法：2024年1月至2024年5月期间所有接受白内障手术或因角膜异常就诊的患者均符合入选条件。两只眼睛都包括在最后的分析中。结果：对43例患者86只眼进行了分析。Eyestar 900 （ES）和Anterion （AN）之间所有数据的平均差异（ES-AN）如下：前房深度(ACD) - 0.080 mm (ICC > 0.926)，轴向长度（AL） 0.015 mm (ICC > 0.99)，角膜中央厚度（CCT） 0.914µm (ICC > 0.921)，沿平子午线(K1) - 0.024 D (ICC > 0.904)，陡峭子午线(K2) - 0.210 D (ICC > 0.902)，白到白角膜直径（WTW） 0.215 mm （ICC > 0.81）。ACD、AL、CCT、K1、K2和WTW具有良好的一致性。然而，角膜轴（AX）仅显示中等一致性（ICC > 0.389），平均差异为5.97°，标准偏差为58.6°。结论：Eyestar 900和Anterion在除角膜子午轴外的所有参数上都表现出基本一致。可以假设，包括不规则角膜地形的眼睛可能导致这种差异。总结：总的来说，Eyestar 900和Anterion之间有很高的一致性。我们有理由认为，在计算人工晶状体的目标屈光结果时，两种仪器提供的测量结果是可以互换的，没有临床相关性差异。
