Influence of the theoretical model eye on the numerical evaluation of fractal intraocular lenses

TL;DR

This study evaluates the optical performance of a new fractal intraocular lens design using ray-tracing, analyzing how different theoretical eye models affect the lens's performance metrics like MTF and AMTF.

Contribution

It introduces a numerical evaluation method for fractal intraocular lenses and examines the influence of different theoretical eye models on their optical performance.

Findings

Performance metrics are consistent across different asphericity values.

Spherical aberration impacts the performance depending on the eye model.

The lens design shows stable behavior regardless of the eye model used.

Abstract

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.
