The IOL includes: an elastic anterior face located anterior to the equator; a posterior face located posterior to the equator, wherein the anterior face, the posterior face, or both comprises a poly(dimethylsiloxane) elastomer having a durometer between about 20 Shore A to about 50 Shore A; and a chamber located between the anterior face and the posterior face comprising a silicone oil comprising polysiloxanes comprising diphenyl siloxane and dimethyl siloxane units, the silicone oil having a maximum viscosity of about 800 cSt at 25° C.

Devices for reconstruction of a lens capsule after cataract surgery

Provided herein are devices used to reconstruct a natural lens capsule after a cataract surgery. The device has a ring-shaped rigid component, a ring-shaped flexible component and a groove disposed on an inner surface of the rigid component. The rigid component has a distal end attached to the ring-shaped flexible component and a proximal end that lies against Wieger's ligament when fitted within the natural lens capsule. The ring-shaped flexible component has a proximal end that is attached to the distal end of the rigid component and a distal end that contacts an anterior surface of the natural lens capsule when fitted therein. The groove is disposed to receive optics of an intraocular lens and/or the ledge is disposed to secure haptics thereof.

Intraocular lenses with pressure sensors embedded therein, and methods of manufacture.

HEAT TUNABLE INTRAOCULAR LENS

A method and system provide an ophthalmic lens including a lens body having a chamber therein, a reservoir module coupled with the lens body and an optical fluid. At least part of the lens body is flexible. The reservoir module includes a reservoir and a heat sensitive portion bordering the reservoir. The reservoir has a reservoir volume and is fluidically connected with the chamber. The heat sensitive portion has a shape responsive to a temperature of at least forty five degrees Celsius such that the reservoir volume changes in response to at least part of the heat sensitive portion reaching the temperature. The optical fluid resides in the chamber and the reservoir. A change in the reservoir volume flows a portion of the optical fluid between the reservoir and the chamber such that the flexible portion of the lens body undergoes a shape change corresponding to a base power change.

ADJUSTABLE INTRAOCULAR LENSES AND METHODS OF POST-OPERATIVELY ADJUSTING INTRAOCULAR LENSES

Disclosed are adjustable accommodating intraocular lenses and methods of adjusting accommodating intraocular lenses post-operatively. In one embodiment, an adjustable accommodating intraocular lens comprises an optic portion and a peripheral portion. At least one of the optic portion and the peripheral portion can be made in part of a composite material comprising an energy absorbing constituent and a plurality of expandable components. At least one of a base power and a cylindricity of the optic portion can be configured to change in response to an external energy directed at the composite material.

FLUID-FILLED HAPTIC FOR AN INTRAOCULAR LENS
20220125576 · 2022-04-28 ·

An IOL utilizes a haptic formed as a toroid portion configured to fit into a capsular bag of an aphakic eye of a patient. The toroid portion may be separate from an IOL optic and may include a receiving feature for the IOL optic. The toroid portion may be configured for intraoperative fluid-filling for snug fitting at the equator of the capsular bag, in order to immobilize the IOL optic.

IMPLANTABLE ACCOMODATING INTRAOCULAR LENSES, IOL IMPLANTS, AND RELATED SYSTEMS AND METHODS
20230293288 · 2023-09-21 ·

An accommodation-facilitating intraocular implant has: a ring sized to fit within a capsular lens bag of an eye; and a plurality of haptics angularly spaced around and radially extended from the ring. A multi-curve implantable accommodating intraocular lens has a convex anterior and concave posterior.

Devices to support and position an intraocular lens within the eye and methods of use

An implantable device for supporting an intraocular lens in an eye including a lens support structure having a central aperture; and one or more fixation arms coupled to the lens support structure and configured to locate and stabilize the device within the eye. Related tools, systems, and methods are provided.

Exchangeable lens platform
11759311 · 2023-09-19 ·

An exchangeable lens platform (ELP) comprises a horseshoe-shaped ring structure, which has a memory strip incorporated therein, into which the haptic end components of the intraocular lens (IOL) can engage diametrically opposite portions of the ring structure. In this manner, the exchangeable lens platform (ELP) can not only be opened or expanded so as to be disposed within any sized capsular bag in a secure and stabilized manner, but diametrically opposite portions of the exchangeable lens platform (ELP) can effectively fold upon themselves such that the exchangeable lens platform (ELP) will effectively be partially folded in half such that the diametrically opposite folded portions of the exchangeable lens platform (ELP) can effectively engage diametrically opposed internal wall portions of the fornix of the capsular bag so as to permit the intraocular lens (IOL) to then be properly centered, oriented, stabilized, and secured within the eye. In addition, since the haptic components of the intraocular lens (IOL) are disposed upon the exchangeable lens platform (ELP) and do not engage internal peripheral wall portions of the capsular bag, the intraocular lens (IOL) can be removed and replaced with another intraocular lens (IOL).

DUAL OPTIC, CURVATURE CHANGING ACCOMMODATIVE IOL
20210361415 · 2021-11-25 ·

The present disclosure concerns a curvature-changing, accommodative intraocular lens (IOL) for implantation in the capsular bag of a patient's eye. The IOL includes a fluid optic body having a cavity for containing an optical fluid, the cavity at least partially defined by a sidewall extending around the cavity and defining a diameter of the cavity and a deformable optical membrane intersecting the sidewall around a circumference of the sidewall and spanning the diameter of the cavity. The IOL further includes a second optic body spaced a distance apart from the fluid optic body and a plurality of struts extending from the sidewall and coupling the fluid optic body to the second optic body. The struts are configured such that axial compression of the capsular bag causes the struts to deform the sidewall in a manner that increases the diameter of the cavity, modifying a curvature of the deformable optical membrane.
