A system includes an intraocular pseudophakic contact lens configured to be implanted in an eye and mounted on or attached to an artificial intraocular lens in the eye. The system also includes an external lens configured to be positioned in front of the eye. The intraocular pseudophakic contact lens and the external lens form a telescopic Galilean vision system. The external lens may include a spectacle lens or a contact lens. The intraocular pseudophakic contact lens may include an optical lens configured to provide a minus power optical magnification, and the external lens may be configured to provide a plus power optical magnification. The optical lens of the intraocular pseudophakic contact lens may include a central portion configured to provide a minus power optical magnification and an annular portion surrounding the central portion and configured to provide a different power optical magnification or no optical magnification.

Intraocular lenses (IOLs) that improve lens stability by, for example, increasing anterior-posterior stiffness of the IOL, increasing anterior-posterior dimensions of the IOL and/or increasing contact area with the equator of the bag to resist movement of the IOL as the bag collapses over time. These IOLs may be non-modular (single component) or modular (multiple component). In modular embodiments, the IOL system may include intraocular base and optic components, which, when combined, form a modular IOL.

An IOL includes a fluid optic body having a cavity defined by a sidewall, a deformable optical membrane intersecting the sidewall around an anterior circumference of the sidewall, and a posterior optic intersecting the sidewall around a posterior circumference of the sidewall. The posterior optic includes a central protrusion extending anteriorly into the cavity and the deformable optical membrane includes a ring-shaped protrusion extending posteriorly into a space between the sidewall and the central protrusion. A second optic body is spaced apart from the fluid optic body and coupled thereto via a plurality of struts. Axial compression causes the plurality of struts to deform the sidewall in a manner that increases the diameter of the cavity, modifying a curvature of the deformable optical membrane is modified. Contact between the ring-shaped protrusion and the central protrusion defines a maximum modification to the curvature of the deformable optical membrane.

An accommodating intraocular lens device is provided. The accommodating intraocular lens device comprises a base assembly and a power lens. The base assembly comprises a first open end, a second end coupled to a base lens, and a haptic surrounding a central cavity. The haptic may comprise an outer periphery, an inner surface and a height between a first edge and a second edge. The power lens is configured to fit within the central cavity. The power lens may comprise a first side, a second side, a peripheral edge coupling the first and second sides, and a closed cavity configured to house a fluid. The first side of the power lens may be positioned at a predetermined distance from the first edge of the haptic.

The present disclosure relates to holders for protecting intraocular lenses and methods of use. The holder includes a posterior wall and an annular wall extending anteriorly from the posterior wall and having an anterior edge. An internal space is defined by the posterior wall and the annular wall. The internal space is sized to receive a lens body of the intraocular lens. The holder also includes a locking feature configured to secure the intraocular lens. At least a portion of the locking feature is anterior to the intraocular lens when positioned in the holder.

An intraocular lens assembly is used in cataract surgery. An intraocular lens assembly (100) has a haptic (102) having a ring (106), a plurality of arcuate arms (108), and a plurality of haptic arm bases (110). Each of the arms (108) is connected with the ring (106) by a respective base (110). An optic (104) has at least two pairs of opposed holes (112). The holes (112) are positioned in the close proximity with an outer peripheral edge of the optic (104). The optic (104) is removably positionable in the haptic (102) by a snap fit lock forming the intraocular lens assembly. The intraocular lens assembly (100) has a first unlocked position wherein haptic (102) is dissembled from the optic (104), and a second locked position wherein the optic (104) is snap fitted in the haptic (102).

An intraocular lens is provided which includes a single optical part, a haptic element, which is coupled to the optical part, and an optical main axis, which penetrates a front face and a rear face of the optical part, the haptic element having a first haptic part, which is in the form of a first ring and extends around the optical part, and at least one second haptic part, which is in the form of a second ring and extends around the optical part and is elastically movable relative to the first haptic part, at least one of the two rings being uneven in the peripheral direction about the optical main axis, at least one of the two rings having exactly two ring valleys and exactly two ring hills.

Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. An apparatus for delivery of a lens component into an eye, including: a nozzle; a housing, wherein the nozzle is operatively coupled to the housing; a first lever; a second lever; and a linkage assembly. The linkage assembly may be disposed within the housing between and adjacent to the first and second levers. The linkage assembly may include a plurality of linkages pivotably coupled to each other, wherein the linkage assembly is collapsible.

An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with fold(s) extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between the inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes. A third lens component coupled to the first or second component provides additional optical power.

An accommodating intraocular lens includes a lens capsule expansion bag placed in a lens capsule whose anterior capsule has been incised in ophthalmic surgery. An intraocular lens is placed in the lens capsule expansion bag. The lens capsule expansion bag includes an anterior bag portion in contact with an anterior capsule, a posterior bag portion in contact with a posterior capsule, and an intermediate bag portion in contact with an equator. The intraocular lens includes an optical portion and a support portion. The support portion includes an anterior support portion in contact with the anterior bag portion and a posterior support portion in contact with the posterior bag portion. In response to the movement of the lens capsule, the lens capsule expansion bag deforms. The anterior support portion of the intraocular lens greatly deflects or returns accordingly, whereby the optical portion is largely moved in the anterior-posterior direction.
