Cataracts are a common ocular pathology involving an increase in the amount of intraocular light scattering. This causes vision impairment by blurring and reducing the contrast in retinal images. The current treatment for this pathology is cataract surgery, which is an invasive procedure with possible side effects, such as corneal edema, infection or retinal detachment among others. In this work, we propose a non-invasive approach to improve vision through the cataractous lenses by manipulating the wavefront of the incident light. By using a fluorescent signal as feedback (similar to the inherent fluorescence of the lipofuscin pigment at the retina) we show the capability of improving the point spread function (PSF) of the eye in a single pass through the artificial eye’s optics, while the feedback signal is measured in a double-pass configuration, making the whole system completely non-invasive, opening new possibilities for real-time vision correction through cataracts with wearable devices.

用于白内障模型散射校正的双通道波前整形

白内障是一种常见的眼部病变,涉及眼内光散射量的增加。这会通过模糊和降低视网膜图像的对比度来导致视力受损。目前对这种病理的治疗是白内障手术,这是一种侵入性手术,可能有副作用,如角膜水肿、感染或视网膜脱离等。在这项工作中,我们提出了一种非侵入性方法,通过操纵入射光的波前来改善白内障晶状体的视力。通过使用荧光信号作为反馈(类似于视网膜上脂褐素色素的固有荧光),我们展示了在单次通过人工眼的光学器件时改善眼睛点扩散函数 (PSF) 的能力,而反馈信号在双通道配置中测量,
