Embodiments of the invention relate to an intraocular lens system having a plurality of haptics for use with an optic. In general, the haptics are adapted to move independently in response to forces associated with a ciliary muscle and/or zonules of an eye when implanted. The optic may be releasably secured to the system using, for example, a plurality of optic securing arms. Alternatively, the optic may be fused to the haptics, which may project radially outward from the optic. A restraining arm may be included to limit movement of the haptics during accommodation and/or disaccommodation. Clamping members may be included for securing the system to a capsular bag of the eye. Methods of implanting the intraocular lens system into the eye are also described.

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 one or more folds of the bellows 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 when the eye accommodates.

Accommodating intraocular lenses containing a flowable media and their methods of accommodation.

The present disclosure provides an intralocular-lens (IOL) or ophthalmic device including an optic and at least one haptic, at least a portion of which is formed from a photoresponsive shape memory polymer network, such as a polydomain azo liquid crystalline polymer network (PD-LCN). The present disclosure further provides systems and methods for adjusting the position of such an IOL or other ophthalmic device using polarized laser radiation.

Hybrid Accommodating Intra Ocular Lens (AIOL) assemblages including two discrete component parts in the form of a discrete base member for initial implantation in a vacated capsular bag and a discrete lens unit for subsequent implantation in the vacated capsular bag for anchoring to the discrete base member. The lens unit includes a lens optics having at least two lens haptics radially outwardly extending therefrom. The base member includes a flat circular base member centerpiece having zero optical power.

Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL) that has a non-zero residual spherical error that requires an estimated diffractive power addition in the IOL. In some embodiments, a plurality of laser pulses are applied to the IOL, the laser pulses being configured to produce, by refractive index writing on the IOL, the estimated diffractive power addition to correct for the residual spherical error.

An intraocular lens (TOL) 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.

A method for preparing a copolymer that involves polymerizing at least one branched alkene monomer and at least one olefin monomer having a pendant benzocyclobutene (BCB) group to form a copolymer comprising a random distribution of a plurality of constitutional units corresponding to the at least one branched alkene monomer and the at least one olefin monomer. The polymerizing includes a carbocationic polymerization reaction involving sequential addition of a plurality of mixtures without terminating the carbocationic polymerization reaction, wherein the plurality of mixtures includes a mixture that includes the at least one branched alkene monomer and does not include the at least one olefin monomer having a pendant BCB group and a mixture that includes both the at least one branched alkene monomer and the at least one olefin monomer having a pendant BCB group. The copolymer composition can undergo crosslinking at elevated temperatures (preferably above 180 C.).

A device according to the present disclosure comprises an intraocular prosthetic. In some embodiments, the device comprises a lens portion and a plurality of arms that radiate outward from the lens portion. The lens portion can comprise a central ring used to hold an intraocular lens. Each arm can comprise a foot plate which allows the device to push out distally against a ciliary body. Among other things, an intraocular device according to the present disclosure can be useful in correction of aphakia, restoration of accommodation, and treatment of glaucoma.

An accommodative intraocular lens capable of effectively exerting a focus adjustment function includes an optical portion and a plurality of support portions arranged around the optical portion. The support portion includes an anterior support portion and a posterior support portion, and the anterior support portion presses an anterior capsule and the posterior support portion presses a posterior capsule by the elastic force of the support portion. When the lens capsule is in a distance vision state or in a near vision state, as the pressing force of the anterior capsule against the anterior support portion increases or decreases, the anterior support portion deflects backward or returns forward while maintaining the radial position of the base end portion, so that the tip end portion of the anterior support portion moves backward or forward greatly while maintaining the radial position, and the optical portion moves backward or forward accordingly.
