    摘要： A diffractive multifocal design for ocular implant is provided. This ocular implant includes a diffractive multifocal intraocular lens (IOL) and a number of haptics. The diffractive multifocal IOL passes optical energy to distance, intermediate and near foci. The haptics mechanically couple to the diffractive multifocal IOL in order to position and secure the diffractive multifocal IOL within the eye. The diffractive multifocal IOL may include both a diffractive region and a refractive region, the diffractive multifocal IOL operable to phase shift optical energy such that constructive interference occurs within the diffractive region and the refractive region.

    摘要： A contact lens has an optical zone with a distance vision zone and a near vision zone. The distance vision zone also has a first area that is sufficient to overlay a substantial portion of a pupil of a user and is disposed in a first position within the optical zone so that the user's pupil is substantially subtended by the distance vision zone when the user is gazing at a substantially horizontal point. The near vision zone is substantially concentric with the rotational axis and extends radially outward from the distance vision zone. The near vision zone has a second radius of curvature that provides near vision correction and has a second area that is sufficient to overlay a substantial portion of the pupil of a user. The near vision zone is disposed in a second position within the optical zone so that the user's pupil is substantially subtended by the near vision zone when the user is gazing at a near vision point below the substantially horizontal point. A ridge zone enables engagement with a lower eyelid of a user so as to provide vertical translation support, and a transition zone provides a smooth transition from the ridge zone to the optical zone.

    摘要： 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.

    摘要： There is provided an intraocular lens, comprising an optic having an anterior surface and a posterior surface disposed about an optical axis, at least one of said surfaces having a profile characterized by superposition of a base profile, the base profile having a base curvature corresponding to a nominal optical power of the lens, and an auxiliary profile, the superposition of the base profile and the auxiliary profile defining a surface comprising an inner refractive region, an outer refractive region and a transition region extending from an outer radial boundary of the inner refractive region to an inner radial boundary of the outer refractive region. The inner refractive region has the base curvature corresponding to the nominal optical power corresponding to a nominal focal plane, the outer refractive region has the base curvature corresponding to the nominal optical power, the transition region (22) is adapted to provide a monotonic change in the optical path difference relative to said outer radial boundary of the inner refractive region (18) as a function of increasing radial distance from the optical axis and wherein the transition region is configured such that an optical phase shift of incident light having a design wavelength across said transition region is defined as: Phase Shift = 2 π λ OPD, in which OPD = the optical phase difference, and λ designates the design wavelength, which is about 550 nm. So that a first portion of an incoming wavefront in the first refractive region and a second portion of the incoming wavefront in the second refractive region converge in front of or beyond the nominal focal plane.
