The present invention provides an accommodative intraocular lens (AIOL) system and method for improving accommodation with an intraocular lens. The method involves insertion into the capsular bag of a flexible optic holder comprising a plurality of haptics configured to allow the capsular bag to be sectioned at regular intervals following fusion of the capsular bag. The haptics of the optic holder are designed to allow maximum fusion of the anterior and posterior leaves of the capsular bag following placement of the optic holder in the capsular bag. Following introduction of the optic holder into the capsular bag, the natural or assisted process of fibrosis/fusion of the capsular bag occurs, thereby sealing and securely capturing the haptics within the capsular bag. Subsequently, several cuts are made in the fibrotic capsular bag at intervals between haptics, allowing the haptics to move independently, thereby effectively restoring some of the flexibility that the capsule possessed prior to fibrosis and restoring some of the zonular force on the capsule.

Embodiments of the invention relate to a flexible, shape-shifting optic adapted to cooperate with a zonular capture haptic system and produce accommodation power both by shape shifting and axial shifting. The optic is designed as a small, thin walled optic vesicle comparable in size to current rigid monofocal IOL optics.

Accommodating intraocular lens including a combination of variable lenses. Firstly, a variable lens including two spherical lenses fitted onto two optical elements to provide variable optical power of which the degree depends on the degree of movement of at least one of spherical lens along the optical axis. Secondly, a variable lens comprising at least two cubic surfaces fitted onto the same two optical elements which provides a lens of variable optical power of which the degree depends on the degree of movement of at least one of the optical elements in a direction perpendicular to the optical axis. The combination of variable lenses is fitted into a mechanical construction providing said movements of the optical elements.

The present disclosure provides a three-lens IOL system including a first, anterior lens, a second, posterior lens rigidly connected to the first lens by at least one rigid member such that the second lens is a fixed distance from the first lens along an axis, a third, center, moveable lens positioned between the first lens and the second lens and adapted to move linearly along the axis anteriorly in a direction of the first lens or posteriorly in a direction of the second lens to change an optical power of the system, and an articulating actuator that contacts the moveable lens and a capsular bag of an eye when the IOL system is implanted in the capsular bag, the articulating actuator adapted to move the moveable lens linearly along the axis.

Lenses and methods are provided for improving peripheral and/or central vision for patients who suffer from certain retinal conditions that reduce central vision or patients who have undergone cataract surgery. The lens is configured to improve vision by having an optic configured to focus light incident along a direction parallel to an optical axis at the fovea in order to produce a functional foveal image. The optic is configured to focus light incident on the patient's eye at an oblique angle with respect to the optical axis at a peripheral retinal location disposed at a distance from the fovea, the peripheral retinal location having an eccentricity between 30 degrees and 30 degrees. The image quality at the peripheral retinal location is improved by reducing at least one optical aberration at the peripheral retinal location. The method for improving vision utilizes ocular measurements to iteratively adjust the shape factor of the lens to reduce peripheral refractive errors.

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.

An intraocular lens (IOL) for implantation within a capsular bag of a patient's eye comprises an optical structure and a haptic structure. The optical structure comprises a planar member, a plano convex member, and a fluid optical element defined between the planar member and the plano convex member. The fluid optical element has an optical power. The haptic structure couples the planar member and the plano convex member together at a peripheral portion of the optical structure. The haptic structure comprises a fluid reservoir in fluid communication with the fluid optical element and a peripheral structure for interfacing to the lens capsule. Shape changes of the lens capsule cause one or more of volume or shape changes to the fluid optical element in correspondence to deformations in the planar member to modify the optical power of the fluid optical element.

An accommodating intraocular lens (IOL) can be implanted either alone or as part of a two-part lens assembly. The IOL comprises an optic, a flexible membrane and a peripheral edge coupling the optic and the flexible membrane. The peripheral edge comprises an external circumferential surface having a height and a force transmitting area defined along a portion of the height of the external circumferential surface. A closed volume spaces apart the optic and the flexible membrane. The optic is axially displaced and the flexible membrane changes in curvature about a central axis when a radial compressive force is applied to the force transmitting area. A volume defined by the closed volume remains fixed when the optic is axially displaced and the flexible membrane changes in curvature and/or when the radial compressive force is applied to the force transmitting area.

The present disclosure provides intraocular artificial lenses having a variable optical strength and methods of treating an eye disorder, such as presbyopia, using same. In some embodiments, the intraocular artificial lens comprises two optical elements that are moveable along the optical axis in relation to each other, for example in response to the accommodative process of the eye.
