COMPOSITE IMPLANTS
20230129084 · 2023-04-27 ·

A composite implant for sustained release of a therapeutic agent in an ocular area of a subject. The composite implant comprises a matrix of photopolymerized polymer formed from a photopolymerizable composition, a biodegradable polymer contained within the matrix, and a therapeutic agent dispersed or dissolved between the matrix and/or biodegradable polymer, wherein the implant is formed from an ocular composition comprising 99 to 60% (w/w) of the photopolymerizable composition. The composite implant can be used in methods of delivering a therapeutic agent to an ocular area in a subject in need thereof, particularly by injecting the implant into the ocular area. Methods of preparing the composite implant are also disclosed.

Re-treatment for ophthalmic correction of refraction

A planning device generating control data for a treatment apparatus for refraction-correcting ophthalmic surgery is provided, said apparatus using a laser device to separate a corneal volume, which is to be removed for correction, from the surrounding cornea by at least one cut surface in the cornea of an eye, said planning device comprising an interface for receiving corneal data including information on pre-operative cuts which were generated in a previous ophthalmic operation, and computing means for defining a corneal cut surface which confines the corneal volume to be removed, said computing means defining the corneal cut surface on the basis of the corneal data and generating a control dataset for the corneal cut surface for control of the laser device.

Biocompatible hydrogel treatments for retinal detachment
11596710 · 2023-03-07 ·

Provided herein are in vivo gelling ophthalmic pre-formulations forming a biocompatible retinal patch comprising at least one nucleophilic compound or monomer unit, at least one electrophilic compound or monomer unit, and optionally a therapeutic agent and/or viscosity enhancer. In some embodiments, the retinal patch at least partially adheres to the site of a retinal tear. Also provided herein are methods of treating retinal detachment by delivering an in vivo gelling ophthalmic pre-formulation to the site of a retinal tear in human eye, wherein the in vivo gelling ophthalmic pre-formulation forms a retinal patch.

Systems and methods for ocular drug delivery

Devices, methods, and kits for ocular drug delivery are described herein. An apparatus can include a housing, an energy storage member, a barrel, and a hub. The housing contains the energy storage member. A proximal end portion of the barrel is coupled to a distal end portion of the housing. The barrel is configured to contain medicament and includes at least a portion of a piston and an elastomeric member. The piston is configured to move the elastomeric member within the barrel in response to a force produced by the energy storage member. The hub is coupled to a distal end portion of the barrel. An inner surface of the hub defines a nozzle through which the medicament flows when the elastomeric member moves within the barrel. The nozzle and the energy storage member are collectively configured to produce a fluid jet to access a target location within an eye.

Amniotic fluid topical formulation

A human amniotic fluid formulation has been developed for topical application to the eye, which is useful for the treatment of ocular diseases and injuries including dry eyes, Sjogren's Syndrome, cataracts, burns and injuries to the eye tissues. The formulation is a sterile de-cellularized human amniotic fluid (D-HAF), devoid of amniotic stem cells and elements of micronized membrane or chorion particles. Methods for treating, or preventing various ocular diseases, injuries and disorders using the formulation, optionally in combination with one or more therapeutic, prophylactic or diagnostic agents are described.

RETINAL PIGMENT EPITHELIUM CELL COMPOSITIONS

Presented herein are ready to administer (RTA) retinal pigment epithelium (RPE) cell therapy compositions for the treatment of retinal degenerative diseases and injuries. A method of formulating human RPE cells for administration to a subject directly after thawing and of formulating RPE cell therapy compositions for cryopreservation and administration of the cryopreserved composition to a subject subsequent to thawing are also presented. In another aspect, the RTA composition may be formulated as a thaw and inject (TAI) composition, whereby the composition is administered by injection subsequent to thawing.

OCULAR IMPLANT CONTAINING A TYROSINE KINASE INHIBITOR

The invention relates to a sustained release biodegradable ocular implant containing a tyrosine kinase inhibitor dispersed in a hydrogel for the treatment of a retinal disease for an extended period of time.

Miniature Fixed and Adjustable Flow Restrictor for the Body

A microfluidic flow restrictor that uses micron-sized beads to impede flow is described. The flow rate can be adjusted by adding or removing the beads using injection needles through self-sealing ports, one injection needle injecting or aspirating beads and another injection needle pushing or pulling fluid from outside of a bead trap within the flow restrictor. In alternative embodiments, the beads or other filler material can be trapped in a manifold bead trap such that they block a subset of fluid channels of the flow restrictor, allowing fluid to flow freely through the rest of the fluid channels. The flow restrictor can be integrated with a contact lens or implantable medical device for use in dispensing liquid therapeutic agents at flow rates of microliters per minute or moving body fluids at a controlled rate from one part of the body to another.

OCULAR APPLICATIONS OF SILK-BASED PRODUCTS
20220323588 · 2022-10-13 ·

The embodiments disclosed and embraced by the present invention include silk-based products useful in the treatment, diagnosis, palliation, and/or amelioration of ocular diseases or conditions of the eye including those of the structures of the eye and surrounding tissue. Such silk-based products may effect beneficial outcomes alone or in combination with therapeutic modalities, compounds or medicaments.

COMPOSITIONS OF EXOSOMES AND AAV

The present disclosure relates to extracellular vesicles, e.g., exosomes, comprising an AAV and a scaffold protein. In some aspects, the AAV is in the lumen of the extracellular vesicle. In some aspects, the AAV is associated with the luminal surface of the extracellular vesicle. In some aspects, the AAV is associated with the exterior surface of the extracellular vesicle. Also provided herein are methods for producing the exosomes and methods for using the exosomes to treat and/or prevent diseases or disorders.
