Paper Abstract

The gradient refractive-index (GRIN) inside the crystalline lens has been described using a number of functions. One of the most widely used functions for this purpose is the polynomial. Changing the order of the GRIN polynomials alters the relative refractive index profile across (radially) and along (axially) the lens. In this paper, numerical methods are used to investigate the effects of varying GRIN polynomial order on the accommodative response of the lens; in particular, accommodative amplitude. Our results suggest that the GRIN order does not have a significant influence on the accommodation amplitude.
