Various embodiments are described herein for an ocular device implantable in a user's eye and which has an adjustable optical element for varying one or more optical properties for the eye such as, but not limited to, providing a dynamically adjustable aperture stop to control the amount of incoming light, filtering incoming light, polarizing incoming light, and/or varying a depth of field for the eye.

COMBINATION BIOACTIVE SILICATE MEDICINE CARRIER AND SHUNT

A combination bioactive silicate (e.g., bioactive glass) medicine carrier and shunt of one embodiment includes a shunt which is a tubular member made of bioactive silicate or glass being adapted to be bioresorbable and water soluble, or fiber bundle, the shunt including an insertion end at a first end. Gaps in the bioactive silicate or gaps in the glass adapted to be bioresorbable and water soluble are served as at least one storage for storing medicines.

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.

Self-Retaining Implantable Drug Delivery Device
20210169690 · 2021-06-10 · ·

Disclosed herein is a medical device for extended release of drugs. The device is a self-retaining implantable drug delivery device embedded with one or more drug depots that release of a therapeutic agent in a controlled manner. Each end of the self-retaining implantable drug delivery device may contain one or more anchors or attachment points which enable self-retention of the medical device once properly placed. The device can also comprise one or more drug depots with a swellable or non-swellable anchor. The disclosed devices further comprises a biosensor to monitor physiological characteristics like, e.g., intraocular pressure (IOP).

WIRELESS DEGRADATION DATA GENERATOR FOR USE WITH A THERAPEUTIC SCAFFOLD AND METHODS FOR USE THEREWITH

A degradation data generator is used with a scaffold for delivery within a patient. The degradation data generator includes a driving circuit electrically coupled to drive an impedance of the scaffold. A detection circuit generates degradation data based on the impedance of the scaffold or other properties such as RF or lightwave transmission, conductance or absorption. The degradation data indicates an amount of biodegradation of the scaffold. A wireless transmitter is coupled to transmit the degradation data to a wireless degradation data receiver, while the scaffold is within the patient.

20210128293 · 2021-05-06 ·

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.

ARTIFICIAL EYE LENS HAVING MEDICINE REPOSITORY FORMED THEREIN, AND METHOD FOR PRODUCING AN ARTIFICIAL EYE LENS
20210161655 · 2021-06-03 ·

The invention relates to an artificial eye lens comprising an optical part, which has a first optical side as viewed in a direction of an optical principal axis of the artificial eye lens and an opposite second optical side, wherein a structure with at least one depression is formed in a haptic arrangement of the artificial eye lens and/or in a surround that surrounds the optical part at least in certain areas and that differs from the haptic arrangement, wherein the structure is formed as a micro-perforation with a multiplicity of perforation zones and at least some perforation zones are filled at least in certain areas with at least one medicament for the purposes of producing a medicament repository. The invention also relates to a method for producing such an artificial eye lens.
