PURPOSE To compare intraoperative and postoperative central vault measurement after implantable Collamer lens (ICL; STAAR Surgical) implantation using optical coherence tomography (OCT). METHODS A total of 574 eyes of 338 consecutive patients undergoing myopic ICL implantation were evaluated (mean age of 30.8 ± 5.7 years, 117 men and 221 women). Central ICL vault was measured both intraoperatively using the microscope-integrated iOCT (Optomedical Technologies GmbH) mounted on a standard surgical microscope (HS Hi-R NEO 900A; Haag-Streit Surgical GmbH), and postoperatively using the CASIA2 swept-source OCT (Tomey GmbH) at 4 and 24 hours. RESULTS Mean differences between intraoperative and postoperative vault values were 11.5 ± 29.0% of the mean value 4 hours postoperatively (P < .001) and 2.7 ± 33.5% of the mean value 24 hours postoperatively (P < .001). Correlation analysis shows significant agreement between vault values obtained intraoperatively and at the two postoperative times, 4 hours (Spearman Rho = 0.850, P < .001) and 24 hours (Spearman Rho = 0.745, P < .001). In 73% of cases, postoperative vault values 4 hours after the surgery could be predicted from intraoperative vault values, and so were 56% of vault values 1 day after surgery. Significant differences in vault were found at the different times, grouping cases by ICL size (Kruskal-Wallis, P = .028 for intraoperative vault, and P < .001 for both postoperative vault times), with smaller vault values for the smaller ICL size. CONCLUSIONS Intraoperative determination of ICL vault using iOCT is an effective method for predicting postoperative ICL vault and minimizing postoperative vault surprises that could require surgical retouching.

在大量患者中植入可植入的 Collamer 晶状体后的术中与术后穹窿测量。

目的 使用光学相干断层扫描 (OCT) 比较植入式 Collamer 晶状体 (ICL; STAAR Surgical) 植入术后的术中和术后中央穹窿测量。方法 对 338 名接受近视 ICL 植入的连续患者的 574 只眼进行评估（平均年龄 30.8 ± 5.7 岁，男性 117 名，女性 221 名）。中央 ICL 穹窿在术中使用安装在标准手术显微镜 (HS Hi-R NEO 900A; Haag-Streit Surgical GmbH) 上的显微镜集成 iOCT (Optomedical Technologies GmbH) 和术后使用 CASIA2 扫源 OCT (Tomey GmbH）在 4 和 24 小时。结果 术中和术后穹窿值之间的平均差异为术后 4 小时平均值的 11.5 ± 29.0% (P < .001) 和 2.7 ± 33。术后 24 小时平均值的 5% (P < .001)。相关性分析显示术中和术后 4 小时（Spearman Rho = 0.850，P < .001）和 24 小时（Spearman Rho = 0.745，P < .001）获得的拱顶值之间存在显着一致性。在 73% 的病例中，术后 4 小时的术后穹窿值可以通过术中穹窿值预测，手术后 1 天的穹窿值也有 56% 可以预测。在不同时间发现穹窿的显着差异，按 ICL 大小对病例进行分组（Kruskal-Wallis，术中穹窿 P = .028，术后两个穹窿时间 P < .001），较小 ICL 大小的穹窿值较小. 结论 术中使用 iOCT 确定 ICL 穹窿是预测术后 ICL 穹窿和最小化可能需要手术修饰的术后穹窿意外的有效方法。[J 屈光手术。2021;37(7):477-483.]。
