Abstract

Cataract is one of the common causes of visual impairment due to opacification of the crystalline lens. In the proposed study, the effect of cataract is simulated and optically corrected in a single-pass system with digital micromirror device (DMD). The correction was carried out by implementing binary amplitude mask which mimics the opacities of the crystalline lens in such a way that the light tends to pass through the transparent parts and there was no light interacting with opacities of cataractous lens. The comparative analysis of the simulated retinal images demonstrates improvement in image quality.
