  In this work we present the numerical evaluation of a new design of fractal
intraocular lens studied through a ray-tracing program. To determine the
monochromatic and polychromatic performance of these lenses in different
theoretical model eyes the Modulation Transfer Function (MTF) and the area
above the MTF (AMTF) have been used. These merit functions show the same
behavior for different values of asphericity (Q), independently from the
theoretical model eye, even though there are differences due to the Spherical
Aberration (SA) considered in each model.
