白内障是可预防性失明和视力丧失的最常见原因，唯一的治疗方法是通过手术用人工晶状体替换自然晶状体。计算机生成全息术 (CGH) 能够控制进入眼瞳的光束的相位、大小和形状。我们开发了全息视觉模拟器来评估患者的视力，以便在手术前体验术后矫正视力。在瞳孔跟踪器的帮助下，使用晶状体的小非白内障区域将全息形状的光束引导到视网膜上。斯内伦图全息图向受试者显示所需深度的近视和远视矫正。对 13 名患者进行的测试表明，视力有显着改善，模拟器结果与术后视力测试一致。全息模拟器的性能优于现有的视觉模拟器，后者仅限于静态针孔出瞳并且无法校正像差。 (c) 2021 年美国光学协会根据 OSA 开放获取出版协议的条款
Cataract is the most common cause of preventable blindness and vision loss where the only treatment is surgical replacement of the natural lens with an intraocular lens. Computer generated holography (CGH) enables to control phase, size, and shape of the light beam entering through the eye-pupil. We developed a holographic vision simulator to assess visual acuity for patients to experience the postoperative corrected vision before going through surgery. A holographically shaped light beam is directed onto the retina using small non-cataractous regions of the lens with the help of a pupil tracker. A Snellen chart hologram is shown to subjects at desired depth with myopia and hyperopia correction. Tests with 13 patients demonstrated substantial improvements in visual acuity and the simulator results are consistent with the post-operative vision tests. Holographic simulator overperforms the existing vision simulators, which are limited to static pinhole exit pupils and incapable of correcting aberrations.
