Abstract

The objective of this paper is a new accommodating opto-mechanical model of the aging human eye for basic simulations of presbyopia, especially of the lens. The lens, consisting of cortex and nucleus, of the aging human eye is mechanically simulated by a FEM model with the program ANSYS. The model results in physiologically correct parameters, and is used as input for a complete optical eye model, implemented in the software ZEMAX. The optical performance of the model corresponds fully with clinical data and the model represents the changes in the mechanical and optical parameters during accommodation and due to the aging process. It is suitable for optical and mechanical simulation; therefore, for example, different possible treatments for presbyopia can be simulated. Furthermore first investigations of stray light due to the laser treatment and their impact on visual performance are presented.
