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.

Improvements to accommodating intraocular optic assemblies are disclosed herein. The accommodating intraocular optic assembly can include an optic and at least one stanchion. The at least one stanchion can extend a length between a base end and a distal end. The distal end can be operably engaged with the optic directly or indirectly. The at least one stanchion can include an outer sleeve defining a through-aperture. The at least one stanchion can also include at least one inner member positioned within the through-aperture.

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 accommodative intraocular lens combination includes mechanically and optically independent lens sections including a static, fixed power lens section to restore refraction of the eye and an, independent, dynamic, variable power lens section to restore accommodation of the eye. The preferred embodiment is a combination of a fixed power lens section, for example, a monofocal intraocular lens implanted inside the capsular bag in combination with a variable power lens section implanted at the sulcus plane and driven by the ciliary mass directly. The lens can include optics comprising free-form surfaces according to orders which exceed third order Zernike and can include additional corrective optics to modulate fixed and variable residual optical.

Lens support structure for supporting an intraocular lens (IOL) is provided, the lens support structure being configured and operable to be securely implanted in a lens capsule of a human eye and hold the IOL in one of a plurality of positions, the support structure comprising a repositioning assembly configured and operable to be activated remotely by a remote energy source and controllably displace the IOL in at least one of directions along and around an optical axis of the IOL, thereby enabling moving the IOL between the plurality of positions. Lens control system is also provided, the control system comprising the lens support structure and a source energy for activating parts thereof. Intraocular lens system is also provided, the system comprising the lens support structure and a lens integrated therein.

Accommodating intraocular lens with an variable power lens with a combination of mechanical driving components which can include a barrel driving component to transfer lateral movement from a driving component in the eye to the variable power lens, and/or a, novel, flange driving component and/or a, novel, bouncing chamber driving component to, firstly, translate axial movement of the ciliary mass and/or the zonular system into lateral movement and, secondly, transfer this lateral movement to the variable power lens.

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.
