An intraocular lens (IOL) with a shape-changing optic is provided. The IOL includes an anterior face and/or a posterior face that is fabricated from a poly(dimethylsiloxane) elastomer having a durometer between about 30 Shore A to about 50 Shore A. A chamber is located between the anterior face and the posterior face and includes a silicone oil including diphenyl siloxane and dimethyl siloxane units. The silicone oil has a maximum viscosity of about 700 mm.sup.2/s at 25° C. and has a mean molecular weight of less than about 3,000 Daltons. An IOL is also provided that includes an anterior face and/or posterior face that is fabricated from a polysiloxane that is at least 99% poly(dimethylsiloxane) elastomer.

Accommodative Functionality for Artificial Capsule Platform
20210353406 · 2021-11-18 ·

A method of using an implantable artificial intraocular lens capsule to provide accommodative functionality through forward backward movement. The implantable artificial capsule has a ring with a central opening to accommodate an intraocular lens and at least three haptic arms extending from the ring. Visual accommodation is accomplished by forward or backward motion of the artificial intraocular lens which is made possible by the flexibility or stimuli induced shape change of the haptic arms. Stimuli include (i) mechanical forces acting on the haptic arms for example by the ciliary muscle, (ii) gravitational forces acting on the artificial intraocular lens, (iii) forces acting indirectly on the haptics arms or (iv) external forces including electrical or electromagnetic delivered via the externalized haptics.

Accommodating intraocular lenses and methods of use

Accommodating intraocular lenses and methods of use. The accommodating intraocular lenses include peripheral regions that are adapted to be more responsive to certain types of forces than to other types of forces. For example, the accommodating intraocular lenses can include haptics that are stiffer in an anterior-to-posterior direction than in a radial direction.

DEVICES TO SUPPORT AND POSITION AN INTRAOCULAR LENS WITHIN THE EYE AND METHODS OF USE
20220000605 · 2022-01-06 ·

An implantable device for supporting an artificial intraocular lens in an eye having an anterior segment of a capsular bag, an iris, and a sclera. The device includes a posterior platform having an anterior-facing surface and an inner wall defining, at least in part, a central aperture. When the device is implanted in the eye, light passes through the intraocular lens and the central aperture of the posterior platform towards the retina. The device includes at least one awning positioned over the anterior-facing surface of the posterior platform forming at least one recess anterior to the posterior platform. The device is configured to be deployed in the eye posterior of the iris so that no portion of the device rests in contact with the sclera after implantation. Related tools, systems, and methods are provided.

Prosthetic capsular devices, systems, and methods

A prosthetic capsular device configured to be inserted in an eye includes a housing structure and a ring structure. The housing structure includes a first side, a second side opposite the first side, a third side, a fourth side opposite the third side, a posterior side including a refractive surface, an anterior side opposite the posterior side, and a longitudinal axis. The first side, the second side, the third side, the fourth side, the posterior side, and the anterior side at least partially define a cavity configured to contain an intraocular device (e.g., an IOL). The anterior side includes an opening. The ring structure includes a ring structure portion extending radially outward from proximate one of an end of the first side and an end of the second side.

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 device also may have a ledge disposed on an inner surface of the flexible 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.

IN-SITU ADJUSTABLE INTRAOCULAR LENS
20230320841 · 2023-10-12 ·

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.

DEVICES TO SUPPORT AND POSITION AN INTRAOCULAR LENS WITHIN THE EYE AND METHODS OF USE
20210338417 · 2021-11-04 ·

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.
