Intraocular lenses with improved visual performance decentered.

摘要

Intraocular lens multielement or multisurface (10, 22) (IOL), comprising: a posterior optical surface (24b, 14a, 14b) and an anterior optical surface (24a, 12a, 12b), wherein at least one optical surface (24b, 14a, 14b) it is adapted to provide compensation for one aberration type and at least one optical surface (24a, 12a, 12b) is adapted to provide compensation for another aberration type characterized in that a combination selected from: the degree of asphericity of the optical surfaces; the Abbe number of lens material; the radii of curvature of the optical surfaces; the axial separation of the optical surfaces; the degree of alignment of the optical axes of the optical surfaces, to, in cooperation, reduce or substantially eliminate, the longitudinal chromatic aberrations exhibited by the intraocular lens (10) and / or to cooperatively provide compensation for natural chromatic aberrations of the eye, such that a plurality of monochromatic, polychromatic and oblique aberrations may be independently corrected and visual performance is enhanced by providing decentered IOL adapted patient having different aberrations compensation and / or different amounts of aberration correction.
