INTRAOCULARLY-MOUNTED OBJECT AND INTRAOCULARLY-MOUNTED OBJECT HOLDING MEMBER
A hook portion 4 is provided which is formed so as to extend from base portions 21a of the ciliary processes 21 along the outer surfaces of the ciliary processes 21 via anterior end portions 21b of the ciliary processes 21 to base portions 21c at the opposite side. A leg portion 3 extending from the hook portion 4 toward the visual axis C is connected to the hook portion 4, and a lens 2 to be mounted in the eye of the patient is supported by the leg portion 3. The lens 2 is held in the eye of the patient in a state where the hook portion 4 is hooked or fitted to the ciliary processes 21.
ACCOMMODATIVE INTRAOCULAR LENS
An accommodating intraocular lens implant is provided that is shaped so as to be assemblable into an assembled state in situ in a capsular bag of a human eye, and includes an anterior floating lens unit, which comprises an anterior lens; a posterior lens unit, which comprises a posterior lens; an anterior rim; levers, arranged to move the anterior floating lens unit toward and away from the anterior rim, in an anterior-posterior direction; and a circumferential rim, which is attached to the levers. The lens implant is arranged such that in the assemble state: elastic potential energy is stored in the lens implant as a result of deformation of the lens implant during a transition from a fully-accommodated state to a fully-unaccommodated state, and at least 50% of the elastic potential energy stored in the lens implant as the result of the deformation is stored in the circumferential rim.
MULTI-PIECE ACCOMMODATING INTRAOCULAR LENSES AND METHODS FOR MAKING AND USING SAME
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.
Accommodating intraocular lens device
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.
CAPACITIVE SENSING CIRCUITS AND METHODS FOR DETERMINING EYELID POSITION USING THE SAME
The present disclosure relates to sensor systems for electronic ophthalmic devices. In certain embodiments, the sensor systems may comprise a first electrode configured to be selectively overlaid by one or more of an upper eyelid and a lower eyelid of a user, a second electrode configured to be selectively overlaid by one or more of an upper eyelid and a lower eyelid of a user, and a system controller cooperatively associated with the first electrode and the second electrode to receive a capacitance measurement therefrom, the system controller configured to determine a position of one or more of the upper eyelid and the lower eyelid in spatial coordinates based on the capacitance measurement received from the first electrode and the second electrode.
INTRAOCULAR LENS AND METHODS FOR ACCOMMODATING EXISTING ADAPTIVE INTRAOCULAR LENSES
An adjustable optical power intraocular lens includes a flexible lens, flexible haptics and flexible cushions. At least one of these elements is made of a UV sensitive material that can be made rigid by UV radiation.
Bifurcated Haptic Aligner-Actuators for Accommodative Intraocular Lenses and Exemplary Aiols Aligned and Actuated Thereby
Bifurcated haptic aligner actuators (BHAAs) have an anterior and a posterior lens support ring to each of which is pivotively attached a plurality of center-pivoted struts, at least two of which comprise an opposing pair, and to each of the opposing pair of struts is pivotably attached a bifurcated haptic, one haptic branch being pivotably attached to the anterior part of a strut, the other branch of the same haptic being similarly attached to the posterior part of the same strut.
Intraocular lens having a haptic that includes a cap
A deformable intraocular has a haptic that supports the optic around its equator and couples the optic to the capsular bag of the eye. The haptic may include a cap on one or both surfaces of the lens. The lens may include a force transfer member-that couples forces from the haptic to the cap, so that a radial force on the haptic changes the curvature of the cap. The cap may be made of the haptic material, which is stiffer than the optic material, and can influence the deformation of the lens during accommodation. A cap on the anterior surface may produce an axial movement of the lens in an anterior direction during accommodation. The cap may also protect the surfaces of the optic during handling and installation.
Crosslinked Polyolefins for Biomedical Applications and Method of Making Same
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.).
