Abstract

PURPOSE

An appropriate vault after implantation of a posterior chamber phakic intraocular lens with a central hole (ICL KS-AP) is important for successful long-term outcomes. In the present study, we used anterior segment optical coherence tomography (AS-OCT) to examine dynamic pupil and vault changes under photopic and scotopic conditions and during accommodation in eyes with ICL KS-AP.

METHODS

This retrospective study included patients at an outpatient ophthalmology clinic who underwent ICL KS-AP implantation >1 month before enrollment. All patients underwent dynamic AS-OCT imaging under photopic and scotopic conditions. Patients aged <40 years also underwent imaging in the accommodative and nonaccommodative states. Primary outcome measures were the pupil size and vault at the maximum and minimum pupil sizes.

RESULTS

This study included 91 eyes of 47 patients (35.5 ± 8.6 years, 21 men). Accommodation was examined in 51 eyes of 26 patients (28.9 ± 5.0 years, 10 men) younger than 40 years. The pupil size was significantly smaller under photopic conditions (3.64 ± 0.77 mm) than under scotopic conditions (4.91 ± 0.75 mm, P < 0.001) and during accommodation (3.88 ± 0.64 vs. 4.10 ± 0.61 mm, P < 0.001). Vault was also significantly lower under photopic conditions (476.1 ± 219.6 μm) than under scotopic conditions (521.1 ± 220.4 μm, P < 0.001) and during accommodation (454.8 ± 224.9 vs. 481.6 ± 219.1 μm, P < 0.001).

CONCLUSIONS

Vault can be significantly lowered by light-induced pupil constriction and accommodation in eyes with ICL KS-AP.

摘要

目的

植入带中心孔的后房型有晶状体眼人工晶状体（ICL KS - AP）后，合适的房角间隙对于长期成功的手术效果很重要。在本研究中，我们使用眼前节光学相干断层扫描（AS - OCT）来检查在明视和暗视条件下以及ICL KS - AP眼调节过程中的动态瞳孔和房角间隙变化。

方法

这项回顾性研究纳入了在门诊眼科诊所就诊的患者，这些患者在入组前1个月以上接受了ICL KS - AP植入术。所有患者在明视和暗视条件下接受动态AS - OCT成像。年龄小于40岁的患者还在调节和非调节状态下进行了成像。主要观察指标是最大和最小瞳孔大小时的瞳孔大小和房角间隙。

结果

本研究纳入了47例患者的91只眼（年龄35.5±8.6岁，男性21例）。对年龄小于40岁的26例患者（年龄28.9±5.0岁，男性10例）的51只眼进行了调节检查。明视条件下的瞳孔大小（3.64±0.77mm）明显小于暗视条件下（4.91±0.75mm，P<0.001）以及调节过程中的瞳孔大小（3.88±0.64对4.10±0.61mm，P<0.001）。明视条件下的房角间隙（476.1±219.6μm）也明显低于暗视条件下（521.1±220.4μm，P<0.001）以及调节过程中的房角间隙（454.8±224.9对481.6±219.1μm，P<0.001）。
