A capsular ring for insertion into a capsular bag of a patient's eye includes an anterior ring defining a first opening and having a first cross-sectional width and a posterior ring defining a second opening and having a second cross-sectional width. A diameter of the first opening is greater than a diameter of the second opening, and the second cross-sectional width is greater that the first cross-sectional width. The capsular ring further includes a sidewall connecting the first ring and the second ring, the sidewall comprising a plurality of orifices spaced circumferentially around the sidewall.

An intraocular assembly includes a peripheral side wall (12) that has a rim (16) sized to receive therein an intraocular device, and a posterior peripheral edge (20) that is sharp and extends out from a posteriorly-facing end face (22) of the side wall. An interior perimeter of the rim is a combination of continuous concave and convex shapes.

A foldable intraocular lens, made from a foldable soft material, for implantation in a ciliary sulcus of an eye having an iris, is provided with an optically active lens part having an optical axis and at least four haptics unitary with the optically active lens part and uniformly spaced about a periphery of the optically active lens part. The optically active lens part having a non-convex rim between any two neighboring haptics being free from surface irregularities that interfere with the iris. Each haptic comprising a closed loop, and a shoulder connecting the loop with the optically active lens part, the haptic loops being elastically deformable in a plane perpendicular to the optical axis of the optically active lens part in a direction toward the optically active lens part.

The present invention relates to a prosthetic capsular bag and method for inserting the same. The prosthetic capsular bag helps to maintain the volume of the natural capsular bag, thereby stabilizing the effective lens position of an IOL so that refractive outcomes may be improved with cataract surgery. The prosthetic capsular bag further provides an integrated refractive surface, providing a means for experimentally determining an effective lens position prior to inserting an IOL.

An accommodating intraocular lens includes a lens capsule expansion bag placed in a lens capsule whose anterior capsule has been incised in ophthalmic surgery. An intraocular lens is placed in the lens capsule expansion bag. The lens capsule expansion bag includes an anterior bag portion in contact with an anterior capsule, a posterior bag portion in contact with a posterior capsule, and an intermediate bag portion in contact with an equator. The intraocular lens includes an optical portion and a support portion. The support portion includes an anterior support portion in contact with the anterior bag portion and a posterior support portion in contact with the posterior bag portion. In response to the movement of the lens capsule, the lens capsule expansion bag deforms. The anterior support portion of the intraocular lens greatly deflects or returns accordingly, whereby the optical portion is largely moved in the anterior-posterior direction.

A method of implanting an intraocular optic assembly that has at least a first and second optics interconnected to one another with a plurality of stanchions can include rotating the first optic and the second optic relative to one another and thereby drawing the stanchions at least one of between the first optic and the second optic and around one of the first optic and the second optic. The method can also include folding, after the rotating, the intraocular optic assembly while retaining the stanchions in the at least one of between the first optic and the second optic and around one of the first optic and the second optic. The method can also include inserting, after the folding, the intraocular optic assembly in an eye through an incision in a cornea of the eye.

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.

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.

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.

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.
