DEVICES TO SUPPORT AND POSITION AN INTRAOCULAR LENS WITHIN THE EYE AND METHODS OF USE
20240074847 · 2024-03-07 ·

A device for supporting an intraocular lens in an eye. The device has a lens support structure having an inner perimeter surface defining, at least in part, a central opening. When implanted, light may pass through the central opening towards the retina. The device has at least three fixation arms, each having an origin portion coupled to the lens support structure and a terminal portion comprising an anchor for trans-scleral fixation of the device. Prior to implantation, at least one fixation arm is biased towards a folded configuration and has a bend between the origin portion and the terminal portion. The origin portion extends away from the lens support structure and the anchor of the terminal portion is positioned over or under at least one of a portion of the lens support structure and a portion of the central opening. Related tools, systems, and methods are provided.

Intraocular lens exchanger

Provided is an intraocular lens exchanger for moving a foldable intraocular lens (IOL), the intraocular lens exchanger including: an outer tube having a first passage formed in a forward/rearward direction; an inner tube disposed to be movable along the first passage and having a second passage formed in the forward/rearward direction; and a variable tube extending from a front end of the inner tube to form a variable passage connected to the second passage, in which the variable tube has an extension part having a width that increases forward in an unconstrained state in which the variable tube is not positioned in the first passage, and the extension part is provided to be elastically deformed when the unconstrained state changes to a constrained state in which at least a part of the extension part is received in the first passage.

Intraocular lens system with folding features

A method of folding and unfolding an active accommodating intraocular lens system includes folding an active lens element along at least one folding line. The at least one folding line is defined by mechanical indentations disposed on a perimeter of the active lens element, and a first pair of the mechanical indentations define terminal ends of a first folding line extending between the first pair of the mechanical indentations. The active lens element is unfolded.

VARIABLE STRENGTH INTRAOCULAR LENS AND METHOD OF USING SAME
20190350700 · 2019-11-21 ·

The present disclosure provides intraocular artificial lenses having a variable optical strength and methods of treating an eye disorder, such as presbyopia, using same. In some embodiments, the intraocular artificial lens comprises two optical elements that are moveable along the optical axis in relation to each other, for example in response to the accommodative process of the eye.

OPHTHALMOSURGICAL INJECTOR SYSTEM
20190192283 · 2019-06-27 ·

An ophthalmosurgical injector system includes an injector, which has a handpiece, a plunger, and a dispensing device; an intraocular lens, which has an optic body and two C-shaped haptic arms protruding therefrom; and a cartridge, in which the intraocular lens is received. The dispensing device has an inlet opening at the proximal end and an outlet opening at the distal end. When the plunger is moved forward, the intraocular lens is conveyed from the cartridge through the inlet opening to the outlet opening of the dispensing device. When the intraocular lens is held in the cartridge in a compressed and preloaded state, a subregion of each of the haptic arms bears on and covers the optic body. In a plan view, the optic body of the preloaded intraocular lens has a circular surface area with a diameter of at least 4.0 mm that is not covered by the haptic arms.

ACCOMMODATING INTRAOCULAR LENS

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.

Shape memory polymer intraocular lenses

A shape memory polymer (SMP) intraocular lens may have a refractive index above 1.45, a Tg between 10 C. and 60 C., inclusive, de minimiz or an absence of glistening, and substantially 100% transmissivity of light in the visible spectrum. The intraocular lens is then rolled at a temperature above Tg of the SMP material. The intraocular device is radially compressed within a die to a diameter of less than or equal to 1.8 mm while maintaining the temperature above Tg. The compressed intraocular lens device may be inserted through an incision less than 2 mm wide in a cornea or sclera or other anatomical structure. The lens can be inserted into the capsular bag, the ciliary sulcus, or other cavity through the incision. The SMP can substantially achieve refractive index values of greater than or equal to 1.45.
