摘要

目的评估通过 Tomey OA-2000 生物测量仪和 Spectralis 光学相干断层扫描(OCT)测量的植入式有晶体眼(ICL)中央穹隆的重复性和一致性:在这项前瞻性研究中,使用Tomey OA-2000生物测量仪和Spectralis光学相干断层扫描测量了ICL植入术后六个月随访的84只眼睛(43名患者)的中央穹隆。由一名经验丰富的技术人员在同一天使用 Tomey OA-2000 和 Spectralis OCT 连续扫描三次。计算变异系数(CoV)、类内相关系数(ICC)、受试者内标准偏差(Sw)和 2.77 Sw,以评估重复性和再现性。采用配对 t 检验和 Bland-Altman 图分析两种仪器测量的中央穹隆的差异和一致性:结果:Tomey OA-2000 生物测量仪和 Spectralis OCT 测量的中央穹隆的重复性显示,CoV 分别为 2.71% 和 1.66%。两种设备的 ICC 分别为 0.996 和 0.999。配对 t 检验显示,Tomey OA-2000 生物测量仪测量的中心穹窿比 Spectralis OCT 测量的中心穹窿低 -7.25 ± 23.57 微米(P = 0.006)。Tomey OA-2000 和 ASM-OCT 测量值之间的平均差异(95% 的一致性限值)为 -38.94 至 53.44 微米:结论:Tomey OA-2000 生物测量仪和 Spectralis OCT 在测量 ICL 中央穹隆时均显示出良好的重复性。Tomey OA-2000 生物测量仪和 Spectralis OCT 之间具有良好的可靠性和一致性。这两种仪器在中心穹隆测量中都很有用,但不能相互替代。

Repeatability and Agreement of Central Vault for Implantable Collamer Lens Obtained by the Tomey OA-2000 Biometer and Spectralis OCT.

Objective: To assess repeatability and agreement of central vault for implantable collamer lens (ICL) measured by the Tomey OA-2000 biometry and Spectralis optical coherence tomography (OCT).

Methods: In this prospective study, the central vault was measured by the Tomey OA-2000 biometer and Spectralis OCT in 84 eyes (43 patients) after ICL implantation at six month follow-up. Three consecutive scans were obtained by one experienced technician using Tomey OA-2000 and the Spectralis OCT in the same day. The coefficient of variation (CoV), intraclass correlation coefficient (ICC), within-subject standard deviation (Sw), and 2.77 Sw were calculated to assess the repeatability and reproducibility. The paired t-test and Bland-Altman plots were used to analyze the differences and agreements of central vault measured by two devices.

Results: Repeatability of the central vault measured by Tomey OA-2000 biometer and Spectralis OCT showed that the CoV was 2.71% and 1.66%, respectively. The ICC for both devices was 0.996 and 0.999, respectively. The paired t-test showed that central vault measured by Tomey OA-2000 biometer was -7.25 ± 23.57 microns lower than that measured by Spectralis OCT (P = 0.006). The mean difference between measurements for Tomey OA-2000 and ASM-OCT with 95% limits of agreement (LoAs) was -38.94 to 53.44 μm.

Conclusion: Both Tomey OA-2000 biometer and Spectralis OCT displayed good repeatability for the measurement of central vault of ICL. Good reliability and agreement were observed between Tomey OA-2000 biometer and Spectralis OCT. Both instruments are useful but not replaced each other for central vault measurements.
