Abstract: Disclosed is an injector which comprises an injector housing having a longitudinal axis and an injection probe disposed along the longitudinal axis. The injector further comprises an intraocular lens disposed in the housing. The intraocular lens comprises first and second interconnected viewing elements, and the optical axes of the first and second viewing elements are substantially aligned. The optical axes are substantially orthogonal to the longitudinal axis of the housing. The injector further comprises a lens carrier which engages one of the viewing elements. The viewing elements are moveable in response to longitudinal movement of the lens carrier relative to the injector housing. The longitudinal movement causes both (i) the optical axes to be displaced relative to each other and (ii) the viewing elements to be disposed substantially on the longitudinal axis of the injector housing.

Abstract: Disclosed are accommodating intraocular lenses for implantation in an eye having an optical axis. In certain embodiments, an intraocular lens includes an anterior optic, a posterior optic, and a support structure configured to move the optics relative to each other along an optical axis between an accommodated state and an unaccommodated state. In certain embodiments, at least a portion of the support structure can be modified in situ to alter reaction forces between the support structure and at least one structure of the eye. In certain embodiments, a refractive property of one of the anterior or posterior optics can be modified in situ while leaving the refractive properties of the remaining one of the anterior or posterior optics substantially unaffected. Additional embodiments and methods are also disclosed.

Abstract: Disclosed is an apparatus for compacting an intraocular lens. The apparatus comprises a lens compactor having a first configuration for retaining the intraocular lens in an unstressed condition and a second configuration in which the compactor stresses the lens into an at least partially compacted condition without advancing the lens along an injection axis of the compactor. The compactor accomplishes this by applying a compacting force in a direction generally orthogonal to the optical axis of the lens. The compactor is responsive to a compactor actuator that is movable by a user to change the compactor from the first configuration to the second configuration. Additional apparatus and methods are disclosed as well.

Abstract: An accommodating intraocular lens has an anterior portion including an anterior viewing element and an anterior biasing element connected to the anterior viewing element. A posterior portion has a posterior viewing element and a posterior biasing element connected to the posterior viewing element. The anterior and posterior biasing elements are connected at first and second apices. First and second distending members are connected to the posterior portion. The first and second distending members extend to locations significantly anterior of an anterior side of the posterior viewing element.

Abstract: An injector for inserting an intraocular lens into an eye includes a lumen. The lumen can include a terminal portion at a distal end and a proximal portion juxtaposed with the terminal portion. An injector plunger can be disposed within the lumen for generating a driving force on the intraocular lens. The injector can include a lens frictional force that has a first value when the lens is at a first location within the proximal portion and a second value when the lens is at a second location within the terminal portion. The first value can be smaller than the second value. In some embodiments, the lens frictional force increases abruptly from the first value to the second value as the lens approaches the distal end of the lumen.

Abstract: Some embodiments provide a copolymer comprising: an acrylate recurring unit and an optionally substituted vinylaryl recurring unit, wherein a portion of at least one of the recurring units comprises a vinyldialkylsiloxy pendant group. The copolymers may be useful as soft acrylic haptics for intraocular lenses. Some embodiments further relate to intraocular lenses having a hydrophobic soft acrylic optic and a silicone haptic, such as a dual optic accommodative lens a having hydrophobic soft acrylic anterior and posterior optic bodies and a silicone haptic. Related copolymeric composite materials as well as additional embodiments of intraocular lenses, are also described herein.

Abstract: A telescopic intraocular lens system comprises a telescopic optical system comprising an anterior optic interconnected with a posterior optic. The optics are substantially aligned on an optical axis of the optical system. The optics are formed from a soft material and the optics are substantially immovable relative to each other along the optical axis in response to accommodative forces of the type observed in the capsular bag of the human eye.

Abstract: A method is provided for implanting an accommodating intraocular lens system in a capsular bag of an eye. The method includes providing the accommodating intraocular lens having an anterior viewing element and a posterior viewing element. The anterior viewing element has a width in a range between approximately 4.5 millimeters and approximately 6.5 millimeters. The method further includes forming an opening in an anterior portion of the capsular bag. The opening has a minimum width not less than approximately 4 millimeters and has a maximum width not greater than approximately 6.0 millimeters. The method further includes placing the accommodating intraocular lens system within the capsular bag. The capsular bag overlaps at least a portion of the anterior viewing element and defines an overlap region with a width in a range between approximately 0.1 millimeters and approximately 0.75 millimeters.
