Paper Abstract

Using raytracing method (ZEMAX program), the reduction of SA of the whole human eye may be reduced via the combined effects of asphericity (Q) and the ratio of the front and back surface of an IOL. The overall SA for best image quality may be defined by Q* when the image position off axis is reduced to that of the paraxial. Our calculations show the following general features: (1) For a give Q value, the influence on the SA is proportional to the surface power; (2) for minimal whole eye SA, negative Q is needed in IOL; (3) for a given IOL power, the Q* is smaller when the front surface has a smaller power. All above features derived from numerical raytracing method are consistent with analytic formulas.
