摘要

目的：利用扫源光学相干断层扫描（SS-OCT）评估植入式角膜塑形镜（ICL）植入术后调节过程中眼前节参数的动态变化：在0.00屈光度（D）、3.00屈光度和最大振幅的调节下，使用SS-OCT检查前节参数，包括ICL穹窿、ICL深度（角膜内皮与ICL后表面之间的距离）、晶状体厚度、前房深度以及前房角的各种参数，包括角膜开口距离、角膜凹陷面积、小梁虹膜空间面积和小梁虹膜角：在适应过程中，ICL穹隆从基线（536 ± 278 μm）显著下降到 3.00 D（522 ± 281 μm），然后从 3.00 D 上升到最大振幅（548 ± 306 μm）（方差分析 [ANOVA]，P < .001）。有四只眼睛（2.61%）显示，在最大调节时，ICL穹隆减小到小于 100 μm（47 ± 32 μm）。随着调节的增加，ICL 深度明显减少（方差分析，P < .001）。晶状体厚度增加，而前房深度在调节过程中减少（方差分析，P < .001）。前房角在 3.00 D 的调节过程中变宽，但在最大调节时变窄，导致调节过程中开角距离、角凹面积、小梁虹膜空间面积和小梁虹膜角发生显著变化（方差分析，P < .001）：前段（包括 ICL 穹窿和前房角）在适应过程中会发生显著的动态变化。结论：ICL穹隆和前房角等前节在适应过程中会发生明显的动态变化，在设计ICL植入手术时需要仔细监测这些适应性变化。[J Refract Surg. 2024;40（3）：e164-e172]。

Anterior Segment Biometry During Accommodation After Posterior Chamber Phakic Implantable Collamer Lens Implantation.

Purpose: To evaluate the dynamic changes in anterior segment parameters during accommodation following Implantable Collamer Lens (ICL) implantation with swept-source optical coherence tomography (SS-OCT).

Methods: Under the accommodation of 0.00 diopters (D), 3.00 D, and maximum amplitude, SS-OCT was used to examine the anterior segment parameters, including ICL vault, ICL depth (the distance between the corneal endothelium and the posterior surface of ICL), crystalline lens thickness, anterior chamber depth, and various parameters of the anterior chamber angle, comprising angle opening distance, angle recess area, trabecular iris space area, and trabecular iris angle.

Results: During accommodation, the ICL vault showed a significant decrease from baseline (536 ± 278 μm) to 3.00 D (522 ± 281 μm), followed by an increase from 3.00 D to maximum amplitude (548 ± 306 μm) (analysis of variance [ANOVA], P < .001). Four eyes (2.61%) exhibited a decrease in ICL vault to less than 100 μm (47 ± 32 μm) at maximum accommodation. The ICL depth decreased significantly as accommodation increased (ANOVA, P < .001). Crystalline lens thickness increased, whereas anterior chamber depth decreased during accommodation (ANOVA, P < .001). The anterior chamber angle widened during 3.00 D of accommodation but narrowed at maximum accommodation, leading to significant changes in the angle opening distance, angle recess area, trabecular iris space area, and trabecular iris angle during accommodation (ANOVA, P < .001 for all).

Conclusions: The anterior segment, including ICL vault and anterior chamber angle, undergo significant dynamic changes during accommodation. These accommodative changes may require careful monitoring for the surgery design of ICL implantation. [J Refract Surg. 2024;40(3):e164-e172.].
