    摘要： 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).

    摘要： 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.

    摘要： 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.

    摘要： The present invention is generally directed to multi-surface and/or multi-element intraocular lenses (IOLs) in which a plurality of surfaces are adapted to provide compensation for a variety of aberrations, and in particular, for off-axis aberrations such as coma or spherical aberration. In one aspect, an intraocular lens is disclosed that includes a posterior optic and an anterior optic. One optic provides compensation for a radially symmetric aberration and the other provides compensation for a radially asymmetric aberration.

    摘要： In one aspect, the present invention provides a method of designing an ocular implant (e.g., an IOL), which comprises establishing corneal topography of a patient's eye, e.g., by performing one or more wavefront aberration measurements of the eye, prior to an ocular surgery. The method further includes ascertaining an astigmatic aberration of the cornea that is expected to be induced by the surgery and determining a toricity of a surface of an ocular implant, which is intended for implantation in the patient's eye, so as to enable the implant to compensate for the surgically-induced aberration.

    摘要： In one aspect, the present invention provides a method of designing a diffractive ophthalmic lens (e.g., an intraocular lens (IOL)) that includes providing an optic having an anterior refractive surface and a posterior refractive surface, wherein the optic provides a far-focus power (e.g., in a range of about 18 to about 26 Diopters (D)). A truncated diffractive structure can be disposed on at least one of the surfaces for generating a near-focus add power (e.g., in a range of about 3 D to about 4 D). And the diffractive structure can be adjusted so as to obtain a desired distribution of optical energy between the near and far foci for a range of pupil sizes.
