  • Patent number: 7922326
    Abstract: An ophthalmic lens for providing a plurality of foci has an optic including an anterior surface, a posterior surface, and an optical axis. The ophthalmic lens further includes a central phase plate, an intermediate phase plate surrounding the central phase plate, and an outer refractive region. The central phase plate comprises a first base curvature having a first radius of curvature and is configured such that the lens is able to direct light to a first focus and a second focus corresponding different diffraction orders of the phase plate. The intermediate phase plate is configured to change the overall resultant distribution of light directed to the second focus. The outer refractive region has no diffractive optical power and surrounds the intermediate phase plate. The outer refractive region is configured to direct light to the second focus and has an aspheric shape configured to reduce an optical aberration.

  • Patent number: 7018409
    Abstract: Intraocular lenses include a lens body sized and adapted for placement in a mammalian eye and having a plurality of different optical powers, and a movement assembly joined to the lens body and adapted to cooperate with the mammalian eye to effect accommodating movement of the lens body in the eye. The lens body has an azonal, aspheric surface, with the correction power of the lens varying continuously and progressively from the optical axis to the periphery of the lens. Such intraocular lenses provide enhanced accommodation relative to the accommodation attainable using a spheric, monofocal IOL adapted for accommodating movement or an aspheric accommodating lens located in a substantially fixed position in an eye.
