To evaluate whether occlusive intraocular lenses (IOLs) produced by several manufacturers for clinical use equivalently transmit near-infrared (IR) light for scanning laser ophthalmoscopy (SLO) or optical coherence tomography (OCT) imaging.

Evaluation of diagnostic test or technology.
The study evaluated 6 black IOLs of 2 designs: 3 poly(methyl methacrylate) (PMMA) and 3 iris-claw anterior chamber IOLs. Each IOL was placed between a broad-spectrum white light source and a spectroradiometer to generate transmission spectra. Transmission in the near-IR range was examined using an 850 nm light-emitting diode. Scanning laser ophthalmoscopy or OCT imaging using Spectralis spectral-domain SLO or OCT was attempted through occlusive IOLs in a model eye.
Artisan iris-claw and MS 612 PMMA occlusive IOLs totally occluded all wavelengths of light, including in the near IR range in which SLO and OCT imaging systems operate. It was not possible to capture SLO or OCT images through the iris-claw and PMMA occlusive IOLs in a model eye.
Results suggest the property of near-IR transmission that permits SLO or OCT imaging through occlusive IOLs is restricted to the Morcher range of occlusive IOLs. Patients with non-near IR transmitting IOLs will not be able to receive detailed posterior segment monitoring with SLO or OCT. This finding may have a significant impact on preoperative occlusive IOL selection and the management of current patients with occlusive IOLs.

评估几种制造商生产的用于临床应用的闭塞性人工晶状体（IOL）是否等效地传输近红外（IR）光用于扫描激光检眼镜（SLO）或光相干断层扫描（OCT）成像。

诊断测试或技术的评估。
该研究评估了 6 个黑色 IOL，包括 2 种设计：3 个聚甲基丙烯酸甲酯（PMMA）和 3 个虹膜爪前房 IOL。每个 IOL 被放置在宽带白光光源和分光辐射计之间，以生成传输光谱。使用 850nm 发光二极管检查近红外范围内的传输。通过模型眼中的闭塞性 IOL 尝试 Spectralis 光谱域 SLO 或 OCT 进行扫描激光检眼镜或 OCT 成像。
Artisan 虹膜爪和 MS 612 PMMA 闭塞性 IOL 完全阻挡了所有波长的光，包括 SLO 和 OCT 成像系统在近红外范围内运行的光。无法通过模型眼中的虹膜爪和 PMMA 闭塞性 IOL 捕获 SLO 或 OCT 图像。
结果表明，允许通过闭塞性 IOL 进行 SLO 或 OCT 成像的近红外传输特性仅限于 Morcher 系列的闭塞性 IOL。具有非近红外传输 IOL 的患者将无法接受 SLO 或 OCT 进行详细的后节监测。这一发现可能对术前闭塞性 IOL 选择以及当前具有闭塞性 IOL 的患者的管理产生重大影响。
