PROSTHETIC CAPSULAR DEVICES, SYSTEMS, AND METHODS
A prosthetic capsular device configured to be inserted in a natural capsular bag of an eye after removal of a lens includes a housing structure capable of containing an intraocular device. The housing structure includes a posterior side, an anterior side opposite the posterior side, lateral sides extending between the posterior side and the anterior side, and a cavity at least partially defined by the posterior side, the anterior side, and the lateral sides. The posterior side includes a refractive surface and an opening radially outward of the refractive surface. The anterior side includes an aperture capable of allowing at least one of insertion, removal, and replacement of an intraocular device. The cavity is capable of containing an intraocular device.
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.
Intraocular pseudophakic contact lens with mechanism for securing by anterior leaflet of capsular wall and related system and method
An apparatus includes an intraocular pseudophakic contact lens having an optical lens and haptics extending radially from the optical lens and configured to be inserted under an anterior leaflet of a capsular wall in an eye in order to capture and confine the haptics under the anterior leaflet and secure the intraocular pseudophakic contact lens against an artificial intraocular lens in the eye. Anterior surfaces of the haptics are configured to contact an inner capsular wall surface at the anterior leaflet. Posterior surfaces of the haptics include ridges configured to capture at least one edge of the artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens. Different portions of the optical lens provide different amounts of magnification such that a first portion of the optical lens provides a first amount of magnification and a second portion of the optical lens provides a second amount of magnification.
Implantable intraocular drug delivery devices
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.
Intraocular drug delivery platform
An intraocular drug delivery platform for use with an intraocular lens assembly. The platform includes a ring and haptics to maintain the ring in position in the capsular bag, compartments on the anterior surface of the ring for accommodating a drug eluting matrix or other drug mass, and a skirt extending posteriorly from the posterior surface of the ring to constrain movement, including lateral or inferior/superior movement, of the intraocular lens relative to the ring.
IMPLANTABLE ACCOMODATING INTRAOCULAR LENSES, IOL IMPLANTS, AND RELATED SYSTEMS AND METHODS
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.
Accommodating intraocular lens device
An accommodating intraocular lens (IOL) can be implanted either alone or as part of a two-part lens assembly. The IOL comprises an optic, a flexible membrane and a peripheral edge coupling the optic and the flexible membrane. The peripheral edge comprises an external circumferential surface having a height and a force transmitting area defined along a portion of the height of the external circumferential surface. A closed volume spaces apart the optic and the flexible membrane. The optic is axially displaced and the flexible membrane changes in curvature about a central axis when a radial compressive force is applied to the force transmitting area. A volume defined by the closed volume remains fixed when the optic is axially displaced and the flexible membrane changes in curvature and/or when the radial compressive force is applied to the force transmitting area.

Intraocular pseudophakic contact lenses and related systems and methods
An apparatus includes an intraocular pseudophakic contact lens. The intraocular pseudophakic contact lens includes a first optical lens and multiple projections extending from the first optical lens. The projections are at least partially coplanar with the first optical lens. The intraocular pseudophakic contact lens also includes multiple anchors partially embedded in or configured to pass through the projections. The anchors are configured to pierce lens material forming a second optical lens of an artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens. The anchors extend along an optical axis of the first optical lens.
Modular intraocular lens designs, tools and methods
Modular IOL removal systems and methods that cut an optic portion of an intraocular in a single motion such to facilitate removal of the optic portion from an eye through an incision, for example a corneal incision, without increasing the size of the corneal incision. Various cutting tools having one or more blades may be utilized. The cut intraocular lens may have one continuous cut or be cut into multiple smaller pieces. The single cutting step may apply balanced forces and torque to avoid damaging the surrounding eye anatomy, reducing the risk of trauma.
