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.

The present disclosure relates to the field of implantable intraocular drug delivery devices. In particular, the present disclosure relates to intraocular drug delivery devices integrated into a capsular tension ring (“CTR”) that is designed for implantation in the capsule or the ciliary sulcus during a cataract extraction and intraocular lens implantation procedure.

An implantable artificial capsule and a method of implantation are provided. The implantable artificial capsule has a ring with a central opening to accommodate an intraocular lens and at least three haptic arms extending substantially orthogonal from the outer surface of the ring. Each arm has transcleral anchors for sutureless scleral fixation. Upon implantation of the implantable artificial capsule the arms are externalized trans-sclerally and atraumatically. The arms sit subconjunctivally. The implantable artificial capsule does not have any sutures for fixation and is suturelessly implanted in an eye, which is a major advantage as it significantly reduces complications during surgery and recovery.

An ophthalmic device includes an optic including an optic axis and a closed-loop haptic structure coupled to the optic via a frame surrounding the optic, the closed-loop haptic structure including a closed loop extending from first and second attachment points to the frame. The closed loop includes a first hinge and a second hinge. The first hinge has a first section having a first component extending in a first angular direction, a second section having a second component extending in a second angular direction opposite to the first angular direction, and a first connecting section between the first section and the second section. The second hinge has a third section having a third component extending in the second angular direction, a fourth section having a fourth component extending in the first angular direction, the fourth section being connected to the second section to form the closed loop.

Devices that include an intraocular pressure sensor and are also adapted to function as a capsular tension ring. The devices include an arcuate body, optionally with first and second free ends, the arcuate body comprising an arcuate antenna and an elastomeric coating layer disposed on the arcuate antenna, and an electronic module adapted to sense intraocular pressure.

A prosthetic capsular device configured to be inserted in an eye after removal of a lens, in some embodiments, can comprise a housing structure comprising capable of containing an intraocular device and an equiconvex refractive surface. The housing structure can comprise an anterior portion comprising an anterior opening, a posterior portion comprising a posterior opening, and a continuous lateral portion between the anterior portion and the posterior portion.

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.

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).
