AI总结：
提出一种基于全息显示和人工眼模型（含巩膜镜片、玻璃视网膜、虹膜及可更换IOL支架）的IOL模拟器，通过计算机生成全息技术引导光束穿过晶状体清晰区，实现白内障患者术前术后视觉体验及多型IOL评估。
摘要：
白内障是一种常见的眼科疾病，其特征是眼睛晶状体内形成浑浊区域，需要通过手术切除并更换晶状体。人工晶状体（IOL）的精心选择对于患者术后的满意度至关重要。尽管市场上有各种具有不同属性的 IOL，但患者很难想象术后他们将如何感知世界。我们提出了一种新颖的全息视觉模拟器，它利用晶状体上的非白内障区域，使白内障患者在术前就能体验术后的视觉敏锐度。计算机生成全息（CGH）显示技术能够使光束成形并引导其穿过患者晶状体相对清晰的区域。白内障手术的另一个挑战是为合适的患者匹配合适的 IOL。为了评估各种 IOL，我们开发了一个由巩膜镜片、玻璃视网膜、虹膜和可更换 IOL 支架组成的人造人眼。接着，我们通过捕捉真实世界场景测试了不同的 IOL（单焦点和多焦点），以展示视觉伪影。然后，该人工眼被安装在台式全息模拟器中，以使用不同的光源和全息内容评估各种 IOL。
英文摘要：
Cataract is a common ophthalmic disease in which a cloudy area is formed in the lens of the eye and requires surgical removal and replacement of eye lens. Careful selection of the intraocular lens (IOL) is critical for the post-surgery satisfaction of the patient. Although there are various types of IOLs in the market with different properties, it is challenging for the patient to imagine how they will perceive the world after the surgery. We propose a novel holographic vision simulator which utilizes non-cataractous regions on eye lens to allow the cataract patients to experience post-operative visual acuity before surgery. Computer generated holography display technology enables to shape and street the light beam through the relatively clear areas of the patient's lens. Another challenge for cataract surgeries is to match the right patient with the right IOL. To evaluate various IOLs, we developed an artificial human eye composed of a scleral lens, a glass retina, an iris, and a replaceable IOL holder. Next, we tested different IOLs (monofocal and multifocal) by capturing real-world scenes to demonstrate visual artifacts. Then, the artificial eye was implemented in the benchtop holographic simulator to evaluate various IOLs using different light sources and holographic contents.
