Us Patents

  • Iol With Varying Correction Of Chromatic Aberration

    view source
  • US Patent:
    20100312337, Dec 9, 2010
  • Filed:
    May 14, 2010
  • Appl. No.:
    12/780381
  • Inventors:
    Xiaoxiao Zhang - Fort Worth TX, US
    Costin Eugene Curatu - Crowley TX, US
    Krishnakumar Venkateswaran - Burleson TX, US
    Daniel Robert Carson - Fort Worth TX, US
    Mutlu Karakelle - Fort Worth TX, US
    Xin Hong - Fort Worth TX, US
    Yueai Liu - Fort Worth TX, US
  • International Classification:
    A61F 2/16
    G02C 7/10
  • US Classification:
    623 631, 351163, 351177
  • Abstract:
    An ophthalmic lens includes an optical filter operable to filter out at least visible light having a wavelength less than 450 nm. The lens also includes a first diffractive structure adapted to produce a focus for visible light in a first wavelength range above 550 nm and to reduce longitudinal chromatic aberration to less than one diopter for incoming visible light in the first wavelength range. The lens also includes a second diffractive structure outside the first diffractive structure in a radial direction and adapted to produce a focus for visible light in a second wavelength range between 450 nm and 550 nm. The second diffractive structure is also adapted to reduce longitudinal chromatic aberration for incoming visible light in the second wavelength range to less than one diopter while allowing longitudinal chromatic aberration in the first wavelength range in an amount greater than the first diffractive structure.
  • Accommodative Iol - Refractive Index Change Through Change In Polarizability Of A Medium

    view source
  • US Patent:
    20130226293, Aug 29, 2013
  • Filed:
    Feb 25, 2013
  • Appl. No.:
    13/775517
  • Inventors:
    Novartis AG - , US
    Krishnakumar Venkateswaran - Burleson TX, US
  • Assignee:
    Novartis AG - Fort Worth TX
  • International Classification:
    A61F 2/16
  • US Classification:
    623 622, 623 637
  • Abstract:
    In one aspect, an accommodative intraocular lens (IOL) is disclosed that includes an optic having at least a portion formed of a polarizable and/or and electro-active material. Once implanted in a subject's eye, a change in the index of refraction of the polarizable and/or electro-active portion in response to forces applied to the optic via the eye's ciliary muscle can cause a change in the optical power of the optic, thereby allowing accommodation.
  • Diffractive Multifocal Intraocular Lens With Modified Central Distance Zone

    view source
  • US Patent:
    20100131060, May 27, 2010
  • Filed:
    Nov 19, 2009
  • Appl. No.:
    12/621613
  • Inventors:
    Michael J. Simpson - Arlington TX, US
    Krishnakumar Venkateswaran - Burleson TX, US
  • International Classification:
    A61F 2/16
  • US Classification:
    623 624
  • Abstract:
    The present invention generally provides multifocal ophthalmic lenses, e.g., multifocal intraocular lenses, that employ a central refractive region for providing a refractive focusing power and a diffractive region for providing diffractive focusing powers. The refractive focusing power provided by the lens's central region corresponds to a far-focusing power that is substantially equal to one of the diffractive focusing powers while the other diffractive power corresponds to a near-focusing power. The far-focusing power can be enhanced by changes to the phase of the central refractive region and/or changes to the curvature of the central refractive region.
  • Distance Dominant Intraocular Lens

  • US Patent:
    20230017040, Jan 19, 2023
  • Filed:
    May 25, 2022
  • Appl. No.:
    17/824450
  • Inventors:
    - Rochester NY, US
    Krishnakumar Venkateswaran - Aliso Viejo CA, US
    Andrew William Jones - Palm Harbor FL, US
    Chun Zhan - Oldsmar FL, US
    Lorenzo Salvatori - Lutz FL, US
  • International Classification:
    A61F 2/16
  • Abstract:
    An intraocular lens includes a base refractive structure having anterior and posterior surfaces that are shaped for producing a first optical power and a diffractive structure formed in one of the surfaces of the base refractive structure including overlapping first and second diffractive patterns over a common aperture for producing second and third optical powers. The second optical power is an uneven division of the third optical power. The first and second diffractive patterns have respective step heights that are separately varied as a function of radial distance from the optical axis over the common aperture.
