Background and ObjectivesTo assess the agreement between Anterion AS-OCT and three optical devices in measuring the white-to-white (WTW) diameter in candidates for refractive surgery.MethodsIn this cross-sectional prospective study, 129 right eyes of 129 normal individuals underwent consecutive scans with the Anterion, the Pentacam AXL, the IOLMaster 700, and the Orbscan IIz. Mean difference (MD), 95% limits of agreement (LoA), and concordance correlation coefficient (CCC) were calculated to assess agreement and interchangeability.ResultsThe mean age of participants was 30.4 ± 5.9 (range: 21-47) years. The mean WTW distance measured by the different instruments was as follows: 12.00 ± 0.42 mm (range, 10.57 to 13.05) using the Anterion, 11.87 ± 0.34 (11.10 to 12.80) using the Pentacam, 12.12 ± 0.44 (11.00 to 13.30) using the IOLMaster, and 11.73 ± 0.37 (11.00 to 13.10) using the Orbscan. The MD and 95% LoA for Anterion vs. Pentacam, IOLMaster, or Orbscan were [0.11; -0.31 to 0.54 mm], [-0.13; -0.93 to 0.66], and [0.25; -0.28 to 0.78], respectively. The corresponding CCCs were 0.803, 0.514, and 0.631.ConclusionsThis study found weak agreement between Anterion and Pentacam AXL, IOLMaster 700, and Orbscan IIz devices regarding WTW distance measurements in refractive surgery candidates. Therefore, it is not recommended to use Anterion's WTW measurements interchangeably with the other three devices, particularly for phakic intraocular lens sizing.
背景与目的
评估Anterion AS-OCT与三种光学设备在测量屈光手术候选者白对白（WTW）直径方面的一致性。
方法
在这项横断面前瞻性研究中，对129名正常个体的129只右眼依次使用Anterion、Pentacam AXL、IOLMaster 700和Orbscan IIz进行扫描。计算平均差异（MD）、95%一致性界限（LoA）和一致性相关系数（CCC）以评估一致性和互换性。
结果
参与者的平均年龄为30.4±5.9（范围：21 - 47）岁。不同仪器测量的平均WTW距离如下：使用Anterion为12.00±0.42毫米（范围，10.57至13.05），使用Pentacam为11.87±0.34（11.10至12.80），使用IOLMaster为12.12±0.44（11.00至13.30），使用Orbscan为11.73±0.37（11.00至13.10）。Anterion与Pentacam、IOLMaster或Orbscan相比的MD和95% LoA分别为[0.11；-0.31至0.54毫米]、[-0.13；-0.93至0.66]和[0.25；-0.28至0.78]。相应的CCC分别为0.803、0.514和0.631。
结论
本研究发现，在屈光手术候选者的WTW距离测量方面，Anterion与Pentacam AXL、IOLMaster 700和Orbscan IIz设备之间的一致性较弱。因此，不建议将Anterion的WTW测量结果与其他三种设备互换使用，尤其是在计算有晶状体眼人工晶状体尺寸时。
