    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: 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.

    Abstract: In one aspect, the present invention provides a two-element ophthalmic lens in which a lateral shift of the elements relative to one another can cause a variation not only in a spherical power provided by the lens but also in spherical aberration exhibited by that lens. In some implementations, the thickness profiles of the two elements are designed such that the variation in spherical aberration is positively correlated with that of the spherical power of the lens.

    Abstract: In one aspect, the present invention provides a method of designing an intraocular lens (IOL) to address variations of at least one ocular parameter in a population of patient eyes. The method can include establishing at least one eye model in which the ocular parameter can be varied over a range exhibited by the population.

    Abstract: In one aspect, a trifocal ophthalmic lens is disclosed that includes an optic having a surface that comprises at least one trifocal diffractive pattern and at least one bifocal diffractive pattern such that the bifocal pattern provides near and far vision and the trifocal pattern generates near, far, and intermediate vision. For example, the trifocal pattern can provide near, far, and intermediate foci such that the near and far foci are substantially coincident, respectively, with a near and a far focus of the bifocal pattern. In this manner, the trifocal and bifocal patterns collectively provide near, intermediate, and far foci (or focal regions) corresponding, respectively, to the near, intermediate and far vision.
