Cataracts is a common ocular pathology where the crystalline lens tends to become opaque, degrading the quality of the retinal images because of the increase of both aberrations and scattering. In this work, we simultaneously generated and optically corrected the effects of cataracts in an optical bench by using a liquid crystal device spatial light modulator. The correction was carried out by implementing a feedback-based wavefront shaping technique with different spatial resolutions of the corrector phase maps. Its benefits were evaluated through objective and subjective descriptors of the quality of vision. The analysis of the experimental results, in addition to numerical calculations of the uncorrected and corrected ocular point spread functions, allowed us to understand the limitations of the technique and to present a strategy to overcome it for future in vivo applications.

基于波前整形的光学模拟白内障矫正

白内障是一种常见的眼病理，其中晶状体倾向于变得不透明，由于像差和散射的增加而降低了视网膜图像的质量。在这项工作中，我们使用液晶装置空间光调制器同时生成并光学校正了光具座中的白内障的影响。通过实施基于反馈的波前整形技术来进行校正，该技术具有不同的校正器相位图空间分辨率。通过对视觉质量的客观和主观描述来评估其益处。除了对未校正和校正后的眼点扩散函数进行数值计算外，还对实验结果进行了分析，体内应用。
