Paper Abstract

The human crystalline lens is a layered structure. Unique protein solution in each individual cell layer gives a different refractive index value thus resulting in a gradient index (GRIN) lens. Crystalline lens GRIN not only provides extra optical power for both relaxed and accommodated eyes, but presumably plays an important role in balancing/reducing eye aberrations and maintaining image quality. In existing eye models, the crystalline lens is either treated as a homogeneous lens or a GRIN lens but with two separate GRIN equations for anterior and posterior segment due to its asymmetrical index distribution along the optical axis. In this study, a single continuous GRIN equation with optical power variability is constructed. A dynamic eye model incorporating this equation for various accommodative states is proposed and simulated in CODEV.
