  • Patent number: 11931244
    Abstract: 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).

  • Publication number: 20210059812
    Abstract: The object of the invention relates to an artificial ophthalmic lens (20) that contains an anterior optical surface (21) and a posterior optical surface (22), where the anterior optical surface (21) and the posterior optical surface (22) have a common optical axis (23), and at least one of the anterior optical surface (21) and the posterior optical surface (22) is a multifocal optics (24) that at least partly has a multifocal optical diffractive profile (25). A cross apodized profile part (25?) is formed on the diffractive profile (25), in other words phase shifting elements (27) are provided on the diffractive profile (25) that alternately form the elements of a decreasingly apodized series (40) and an increasingly (reversed) 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).
