Abstract: In one aspect, the present invention provides an ophthalmic lens (e.g., an IOL) that includes an optic having an anterior surface and a posterior surface disposed about an optical axis. At least one of the surfaces (e.g., the anterior surface) has a profile characterized by superposition of a base profile and an auxiliary profile. The auxiliary profile can include an inner region, an outer region and a transition region between the inner and the outer regions, where an optical path difference across the transition region (i.e., the optical path difference between the inner and the outer radial boundaries of the transition region) corresponds to a non-integer fraction (e.g., ½) of a design wavelength (e.g., a wavelength of about 550 nm).

Abstract: In one aspect, the present invention provides a method of correcting vision, which comprises determining a residual accommodation exhibited by a natural, crystalline lens of an eye, and selecting a multifocal intraocular lens (IOL), which exhibits a far-focus optical power (e.g., in a range of about −15 to about +50 Diopters (D)) and an add power (e.g., in a range of about 1 D to about 4 D), for implantation in the eye while retaining the natural lens. The add power of the IOL is selected as a function of the residual accommodation such that a combination of the IOL and the natural lens provides a visual contrast greater than about 10% at a spatial frequency of about 20 cycles/degree for viewing objects at a distance greater than about 30 cm from the eye.

Abstract: An accommodating intraocular lens (AIOL) includes an optic adapted to produce a trapezoidal phase shift and a plurality of haptics. Each haptic extends from a haptic-optic junction to at least one transverse arm contacting a capsular bag of the eye, and each haptic has sufficient length and rigidity to stretch a capsular bag of the eye to contact ciliary muscles of the eye. The haptic-optic junctions vault the optic forward relative to the haptics and compression of the haptics by the ciliary muscles moves the anterior optic forward. A combined accommodative power produced by the motion of the anterior optic and the trapezoidal phase shift is at least 0.5 Diopters.

Abstract: 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.

Abstract: Intraocular lenses (IOLs) with modified edge characteristics are disclosed to inhibit transverse propagation of internally reflected light rays in order to alleviate, and preferably eliminate, dysphotopsia and/or the perception of dark shadows reported by some users. In one embodiment, IOL designs are disclosed that incorporate an opaque edge or other mechanisms for capturing internally reflected peripheral light rays. In other embodiments, the peripheral region can include a light scattering material or can have a disproportional thickness or be contoured to redirect peripheral rays.
