Intraocular lens with focal performance tailored to pupil size deploying refractive power modification along spiral tracks

Abstract

A new family of intraocular lenses that exhibit an extended depth of focus or a tailored multifocality where the lenses are designed by the combination of a base lens topology and additional refractive power range described along a spiral-like grid. The variety of parameters confer a great versatility to the lens design, which allows the achievement of the best suitable features to attend to a wide range of visual demands in performing different activities. It is possible to set the parameters to specify apt-focal lenses that account for optical performance changes due to pupil aperture variations, as well as to counter positive dysphotopic effects.
