The invention relates to an artificial ophthalmic lens () containing an anterior optical surface () and a posterior optical surface (), at least one of which contains a multifocal optical diffractive profile (). A cross apodized profile part (′) is formed on the diffractive profile () wherein phase shifting elements () are provided alternately forming the elements of a decreasingly apodized series () and an increasingly apodized series () in such a way that the decreasing and increasing elements of the two series () form envelope curves that meet at a common intersection point (). The invention further relates to a method for the production of such an artificial ophthalmic lens ().

Diffractive artificial ophthalmic lens with optimised apodization and method for the production of such artificial ophthalmic lens

The invention relates to a trifocal artificial ophthalmic lens (), which contains an anterior side optical surface (), a posterior side optical surface () and an optical axis (), at least one of the anterior side optical surface () and the posterior side optical surface () contains an optics having three useful focal points and having an at least partially diffractive profile. The three useful focal points correspond to focal points () belonging to the 0and 1diffraction orders of the diffractive profile, and to a focal point () belonging to an enhanced diffractive secondary peaks between the 0and the 1diffraction orders. The invention also relates to a method of producing the aforementioned trifocal artificial ophthalmic lens.
