20190091008 · 2019-03-28 ·

A toric intraocular lens includes a lens body, support portions, and connecting portions for connecting the lens body and the support portions. The lens is housed in an insertion apparatus that includes a tubular apparatus body having an insertion tube for the lens and a plunger for moving the lens. Each of the connecting portions is arranged at a position where the connecting portions face each other across a center of an optical axis of the lens body. One end of the flat meridian of the lens body is located at a position opposite to a position, with respect to an axis that passes through the center and connects the connecting portions, at which the plunger contacts the lens body. An angle between the flat meridian and an axis along which the lens is pushed by the plunger is larger than 0? and equal to or smaller than 90?.

INTRAOCULAR LENS HAVING AN ASYMMETRIC HINGED CLOSED-LOOP HAPTIC STRUCTURE
20190053891 · 2019-02-21 ·

An ophthalmic device includes an optic having an optic axis and a closed-loop haptic structure coupled with the optic. The closed loop haptic structure includes a first hinge having a first section, a second section, and a connecting section extending between the first section and the second section. The first section has a first component extending in a first angular direction and a second component extending in a second angular direction that is opposite to the first angular direction. The closed loop haptic structure further includes a second hinge including a radial section and an axial section extending from the axial section in the first angular direction, the radial section having a cross-sectional area greater than a maximum cross-sectional area of the first hinge.

INJECTOR, INTRAOCULAR LENS SYSTEM, AND RELATED METHODS

An intraocular lens system may include a base that may include an annular body, an opening extending through the annular body in an axial direction of the annular body, and a recess extending circumferentially about the opening. The system also may include a lens that may be insertable into and removable from the recess. The lens may include a central optic, a first tab protruding radially away from the central optic, and a second tab protruding radially away from the central optic. The second tab may be more resistant to compression in a radial direction than the first tab. The first tab may include a first arm protruding radially away from the central optic, a second arm protruding radially away from the central optic and extending away from the first arm, and a third arm extending from the first arm to the second arm. Movement of one or more of the first, second, and third arms may result in deformation of the first tab.

COMPOSITE LIGHT ADJUSTABLE INTRAOCULAR LENS

A composite light adjustable intraocular lens, can include an intraocular lens (IOL), a light adjustable lens, attached to the intraocular lens, and haptics. In some cases, a composite light adjustable intraocular lens can include an intraocular lens, and haptics, attached to the IOL with light-adjustable hinges. A method of adjusting an implanted composite light adjustable intraocular lens can include planning a targeted optical outcome of an implantation of the composite light adjustable intraocular lens into an eye; implanting, the composite light adjustable intraocular lens into the eye; performing a diagnostic measurement to evaluate an implanted optical outcome of the implantation; determining a correction based on a comparison of the planned optical outcome and the implanted optical outcome; and applying a stimulus to adjust an optical characteristic of the composite light adjustable intraocular lens to induce the determined correction.

POSTERIOR CHAMBER INTRAOCULAR LENS WITH SWIVEL HAPTICS FOR CAPSULOTOMY FIXATION
20180280133 · 2018-10-04 ·

The present disclosure relates to a posterior chamber intraocular lens with swivel haptics for capsulotomy fixation in an eye. The posterior chamber intraocular lens includes a circular optic and at least one pair of swivel haptics. The circular optic is configured to be positioned within a capsular bag of the eye. The circular optic includes plurality of positioning holes on a periphery. The at least one pair of swivel haptics is positioned on the circular optic. The at least one pair of swivel haptics is configured to be rotated away from the circular optic and fixed above an anterior capsule of the eye.

FLEXIBLE INTRAOCULAR LENS HAVING MUTLIPLE YOUNG'S MODULI
20180235751 · 2018-08-23 ·

A method and system provide an ophthalmic device including an optic and a haptic. The optic includes at least one optical material having a first Young's modulus. The haptic is coupled with the optic. The haptic includes at least a second Young's modulus greater than the first Young's modulus and less than 1.8 GPa. Thus, the haptic is stiffer than the optic, but more flexible than a material such as polymethyl metacrylate (PMMA).

In-situ adjustable intraocular lens
12193929 · 2025-01-14 · ·

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.

HAPTIC FOR ACCOMMODATING INTRAOCULAR LENS
20170135810 · 2017-05-18 ·

A haptic is provided for use in an accommodating intraocular lens. The haptic has multiple filaments, each connected to the edge of the optic at one end. Each filament has a shape that conforms to an equatorial region of the capsular bag. The haptic couples the forces exerted by the capsular bag of the eye during accommodation radially to the edge of the optic, produce a diametric expansion or compression of the optic. This diametric motion distorts the optic, producing a change in any or all of the anterior radius, the posterior radius, and the thickness. These changes affect the power of the lens and/or location of the image. The haptic may optionally have a thin membrane joining the filaments at the optic end, and may optionally have a connecting ring that joins the filaments at the end opposite that of the optic.
