Development of an Improved Digital Glare Testing Device

描述(申请人提供)随着屈光手术的普及，手术前和手术后患者对眩光评估的准确评估工具的需求也在增加。目前的眩光测试仪器在眩光刺激存在的情况下不能准确地重建眼睛的生理状况。基于对在不改变眼睛光学参数的情况下评估视觉性能的改进仪器的需求，InterScience提出了基于数字微镜阵列技术的眩光残疾评估仪器的高级开发。实际评估方法不会与既定程序不同，即使用既定视力表(EDTRS、Landolt环等)测试视力。在各种光照条件下，包括眩光。这项工作的目标是通过开发具有静态、动态和定制眩光源呈现的改进的仪器来增加眩光测试的灵活性。拟议的工作旨在设计、开发和演示数字眩光 测试装置。在第一阶段的工作中，成功地展示了该设备的适应性和灵活性，包括动态眩光源的呈现、测试图表中的多种对比度级别、眩光源大小、强度和位置的可编程变化，以及用户友好的计算机控制系统。第二阶段的工作将通过先进的系统开发和临床患者测试，将原型系统转移到商业上可行的数字眩光测试设备。

DESCRIPTION (provided by applicant) As the popularity of refractive surgery increases, so does the need for an accurate evaluation tool for glare assessment in both the pre- and post-surgical patient. Current glare testing instrumentation does not accurately recreate physiologic conditions in the eye in the presence of glare stimuli. Based on the need for improved instrumentation that assesses visual performance without changing the optical parameters of the eye, InterScience proposes the advanced development of glare disability assessment instrumentation, based on the digital micromirror array technology. The actual means of assessment will not differ from established procedures, i.e. testing visual acuity with established vision charts (EDTRS, Landolt ring, etc.) under various lighting conditions including glare. The goal of this work is to increase the flexibility in glare testing through the development of improved instrumentation with static dynamic and custom glare source presentation. The proposed effort is aimed at the design, development, and demonstration of a Digital Glare Testing Device. In the Phase I effort, the adaptability and flexibility of the device, including the presentation of dynamic glare sources, numerous contrast levels in test charts, programmable variations in size, intensity and location of the glare source, and a user friendly computer control system were successfully demonstrated. The Phase II effort will transfer the prototype system to a commercially viable Digital Glare Testing Device through advanced system development and clinical patient testing.
