An intraocular optic assembly can include a plurality of stanchions and at least one optic. Each of the stanchions can extend between a respective base and distal ends. The base ends can be disposed in spaced relation to one another about a first arcuate periphery. The distal ends can be disposed in spaced relation to one another about a second arcuate periphery. The first arcuate periphery can have a greater radius than the second arcuate periphery. The at least one optic can have a central optic axis, an anterior side, a posterior side, and a center disposed between the anterior side and the posterior side through which the central optic axis extends. The at least one optic can be connected with each of the plurality of distal ends whereby the center of the optic is moved along the central optic axis in response to contraction of the first arcuate periphery.

A lens configured for implantation into an eye of a human can include an optic including transparent material. The optic can have an anterior surface and a posterior surface. The anterior surface can be convex and the posterior surface can be concave such that the optic is meniscus shaped. Each of the convex anterior surface and the concave posterior surface can have a surface vertex. The optic can have an optical axis through the surface vertices and a thickness along the optical axis that is between about 100-700 micrometers. The lens can also include haptic portions disposed about the optic to affix the optic in the eye when implanted therein. The anterior and posterior surfaces can include aspheric surfaces.

The present invention relates to a first intraocular lens (120) embodiment having a retainer plate (124) with an annular region surrounding a central opening and an optical lens (122) removably attached to the retainer plate within the central opening. Also disclosed is a second intraocular lens embodiment having a retainer plate with a porous or perforated annular region surrounding a central opening. An optical lens (122) is integral with the retainer plate (124) within the central opening. Methods of implanting these intraocular lens (120) embodiments into a patient's eye are disclosed. Also described here are methods of replacing the first intraocular lens embodiment after it has been implanted in a patient's eye.

Methods of vision correction that include implanting a first lens and a second lens of a lens pair. The methods include implanting the first lens into a first eye of the subject, the first lens configured with first extended depth of field, and implanting the second lens into a second eye of the subject, the second lens configured with second extended depth of field, where the second eye is different than the first eye.

The embodiments disclosed herein include improved toric lenses and other ophthalmic apparatuses (including, for example, contact lens, intraocular lenses (IOLs), and the like) and associated method for their design and use. The apparatus includes one or more optical zones, including an optical zone defined by a polynomial-based surface coincident at a plurality of meridians having distinct cylinder powers, wherein light incident to a given region of each of the plurality of meridians, and respective regions nearby, is directed to a given point of focus such that the regions nearby to the given region direct light to the given point of focus when the given meridian is rotationally offset from the given region, thereby establishing an extended band of operation, and wherein each of the plurality of meridians is uniformly arranged on the optical zone for a same given added power (in diopters) up to 1.0 D (diopters).

The embodiments disclosed herein include improved toric lenses and other ophthalmic apparatuses (including, for example, contact lens, intraocular lenses (IOLs), and the like) that includes a freeform-polynomial surface area that establishes a band of operational meridian for the apparatus to an intended correction meridian. The freeform-polynomial surface area is defined by a mathematical expression comprising a combination of one or more polynomial expressions (e.g., Chebyshev-based polynomial expression, Zernike-based polynomial expression, etc.) each having a distinct complex orders.

A lens configured for implantation into an eye of a human can include an optic including transparent material. The optic can have an anterior surface and a posterior surface. The anterior surface can be convex and the posterior surface can be concave such that the optic is meniscus shaped. Each of the convex anterior surface and the concave posterior surface can have a surface vertex. The optic can have an optical axis through the surface vertices and a thickness along the optical axis that is between about 100-700 micrometers. The lens can also include haptic portions disposed about the optic to affix the optic in the eye when implanted therein. The anterior and posterior surfaces can include aspheric surfaces.

Methods of vision correction that include implanting a first lens and a second lens of a lens pair. The methods include implanting the first lens into a first eye of the subject, the first lens configured with positive extended depth of field, and implanting the second lens into a second eye of the subject, the second lens configured with negative extended depth of field, where the second eye is different than the first eye.

Disclosed are ophthalmic lenses, ophthalmic lens components, and methods, systems, and apparatus for manufacturing an ophthalmic lens component. In one aspect, disclosed is an intraocular lens, comprising an optic portion and a haptic coupled to the optic portion. The haptic can comprise a haptic anterior portion and a haptic posterior portion. The haptic anterior portion can have an anterior surface roughness and the haptic posterior portion can have a posterior surface roughness. The posterior surface roughness can be greater than the anterior surface roughness such that at least part of the haptic anterior portion is smoother than the haptic posterior portion.

Disclosed are tunable intraocular lenses and methods of adjusting a cylinder power of an intraocular lens. In one aspect, the intraocular lens can comprise an optic portion. The optic portion can comprise a first polymeric bead located at a first location along an exterior of the optic portion and a second polymeric bead located at a second location along the exterior of the optic portion diametrically opposed to the first location.
