To newly describe the vault measurement by using a widely used swept-source OCT-based optical biometer (IOLMaster700) and accessd the accuracy of vault measurement.
This was a retrospective, cross-sectional study. All patients underwent implantable Collamer lens (ICL) implantation surgery without complications. IOLMaster700 and AS-OCT analyses were conducted for each eye on the same day in the same condition. Measurements of anterior chamber depth (ACD), corneal-ICL (C-ICL), and vault values were made and recorded. The repeatability of the IOL Master700 measurements was quantified based upon intraclass correlation coefficient (ICC) values. Correlations between IOL Master700 and AS-OCT measurements made with these different analytical approaches were assessed. The agreement of instruments was evaluated using Bland-Altman plots.
The IOLMaster700 instrument yielded highly reliable measurements of vault, C-ICL, and ACD ( = 0.996, 0.995, 0.995, respectively). Vault, C-ICL and ACD values as measured using the IOLMaster700, was slightly smaller than that measured via AS-OCT, but these differences were not significant ( = 0.652 = 0.121 and = 0.091, respectively). The vault, C-ICL, and ACD measurements by these two instruments were strongly correlated ( = 0.971, = 0.944, and = 0.963, respectively; all < 0.001). The 95% limits of agreement for vault, C-ICL, and ACD measurements between the two devices were-0.08 to 0.08 mm,-0.14 to 0.11 mm, and-0.13 to 0.10 mm, respectively.
The IOLMasrer700 can measure implanted ICL vault with a high degree of accuracy and repeatability. Good correlations and agreement were observed between IOLMaster700 and AS-OCT in measuring vault, C-ICL, and ACD measurements.
首次描述使用广泛应用的基于扫频源光学相干断层扫描技术的光学生物测量仪（IOLMaster700）测量房角，并评估房角测量的准确性。
这是一项回顾性横断面研究。所有患者均接受了可植入式胶原晶状体（ICL）植入手术，且无并发症。在同一天、相同条件下对每只眼睛进行IOLMaster700和眼前节光学相干断层扫描（AS-OCT）分析。测量并记录前房深度（ACD）、角膜-ICL（C-ICL）和房角值。基于组内相关系数（ICC）值对IOL Master700测量的重复性进行量化。评估IOL Master700与采用这些不同分析方法的AS-OCT测量结果之间的相关性。使用Bland-Altman图评估仪器的一致性。
IOLMaster700仪器对房角、C-ICL和ACD的测量具有高度可靠性（ICC分别为0.996、0.995、0.995）。使用IOLMaster700测量的房角、C-ICL和ACD值略小于通过AS-OCT测量的值，但这些差异不显著（P分别为0.652、0.121和0.091）。这两种仪器对房角、C-ICL和ACD的测量结果高度相关（r分别为0.971、0.944和0.963；均P<0.001）。两种设备之间房角、C-ICL和ACD测量的95%一致性界限分别为-0.08至0.08mm、-0.14至0.11mm和-0.13至0.10mm。
IOLMasrerl700能够高度准确且可重复地测量植入的ICL房角。在测量房角、C-ICL和ACD时，IOLMaster700与AS-OCT之间观察到良好的相关性和一致性。
