The present invention is generally directed to multi-surface and/or multi- element intraocular lenses (IOLs) in which a plurality of surfaces are adapted to provide compensation for a variety of aberrations, and in particular, for off-axis aberrations such as coma or spherical aberration. In one aspect, an intraocular lens is disclosed that includes a posterior optic and an anterior optic. One optic provides compensation for a radially symmetric aberration and the other provides compensation for a radially asymmetric aberration.
La présente invention concerne, de manière générale, des implants intraoculaires multi-surfaces et/ou multi-éléments dans lesquels une multitude de surfaces sont conçues pour compenser une grande variété d'aberrations, et en particulier les aberrations hors axe, telles que l'aberration de coma ou l'aberration sphérique. Dans un seul aspect, elle porte sur une lentille intraoculaire incluant un optique postérieur et un optique antérieur. Un optique permet de compenser l'aberration symétrique radialement, tandis que l'autre compense l'aberration asymétrique radialement.
