DIFFRACTIVE ARTIFICIAL OPHTHALMIC LENS WITH OPTIMISED APODIZATION AND METHOD FOR THE PRODUCTION OF SUCH ARTIFICIAL OPHTHALMIC LENS

The invention relates to an artificial ophthalmic lens (20) containing an anterior optical surface (21) and a posterior optical surface (22), at least one of which contains a multifocal optical diffractive profile (25). A cross apodized profile part (25′) is formed on the diffractive profile (25) wh...

Zusammenfassung:The invention relates to an artificial ophthalmic lens (20) containing an anterior optical surface (21) and a posterior optical surface (22), at least one of which contains a multifocal optical diffractive profile (25). A cross apodized profile part (25′) is formed on the diffractive profile (25) wherein phase shifting elements (27) are provided alternately forming the elements of a decreasingly apodized series (40) and an increasingly apodized series (41) in such a way that the decreasing and increasing elements of the two series (40, 41) form envelope curves that meet at a common intersection point (45).The invention further relates to a method for the production of such an artificial ophthalmic lens (20).
