Amniotic or placental device for ophthalmic use as a dressing with refractory center section
11628189 · 2023-04-18 ·

A biodegradable lens-shaped patch useful for healing and treatment of ocular conditions is disclosed. The patch is formed from a biodegradable carrier which carries amniotic extract and/or placental extract. The lens-shaped patch may be shaped in the form of a conventional contact lens and it is applied to a corneal surface to enhance healing thereof. After a certain period of time, the patch dissolves on its own and it need not be removed from the eye by a clinician. In an embodiment, the patch includes a clear central section that may be refractory, and a biodegradable peripheral section.

Adjustable intraocular lenses and methods of post-operatively adjusting intraocular lenses

Disclosed are adjustable accommodating intraocular lenses and methods of adjusting accommodating intraocular lenses post-operatively. In one embodiment, an adjustable accommodating intraocular lens comprises an optic portion and a peripheral portion. At least one of the optic portion and the peripheral portion can be made in part of a composite material comprising an energy absorbing constituent and a plurality of expandable components. At least one of a base power and a cylindricity of the optic portion can be configured to change in response to an external energy directed at the composite material.

PREPARATION METHOD AND APPLICATION OF ION-ACTIVATED BIOADHESIVE HYDROGEL
20230110021 · 2023-04-13 ·

A composite hydrogel contains alginate hydrogel and acellular matrix hydrogel. The ingredients used to produce the acellular matrix hydrogel contains acellular matrix and transglutaminases (TGases). The alginate hydrogel contains salginate complex. The alginate hydrogel and acellular matrix hydrogel constitute a three-dimensional crosslinking structure. The TGases can catalyze isopeptide bonding between acellular matrixes, and thus forms acellular matrix hydrogel through crosslinking.

Nucleo-reticular multi-cell dual-system eye implant
11654013 · 2023-05-23 ·

The Nucleo-reticular Multi-cell Dual-system Eye Implant consists of a spherical structure with calculated and variable axial length depending on the needs required by the orbital eye socket, composed of a cell mesh with alternative designs that in turn, makes up the MMM System, in which suturing is provided in any technique, either in cases of evisceration or enucleation. Thanks to its multi-cell structural design, it favors its placement and reduces the risk of migration, extrusion, exposure and extraction. As it is an arrangement with structural holes, it provides a higher percentage of the volume for its vascularization; it also houses inside a Reticular Fibrovascular Core System, which has a structure based on multilevels equipped with micro-reticular tissue and an intra-level communication based on filaments; with the capacity to contain medicines and/or technology by presenting a dual-system of two screw-on pieces, being able to manufacture in different structural designs and biocompatible materials. The C100 model made of polylactic acid (PLA), an ideal material for implants, consists of 100 oval cells. Since it is a light eye implant, it prevents depressure due to settlement or gravity and it can be manufactured in any size.

DSAEK corneal graft assemblies for optimized surgical operations
11654048 · 2023-05-23 · ·

Assemblies for storing, handling, transporting, viewing, evaluating, and/or shipping corneal tissue are provided. The assembly includes a corneal tissue carrier, optimized for DSAEK and UT-DSAEK corneal grafts, within a transport vial, the transport vial removably coupled to a stabilization base, wherein the ease of access to the graft carrier allows administering the corneal tissue sample to a patient in rapid succession so that more surgeries can be performed by a single surgeon in a single day.

20170368377 · 2017-12-28 ·

Provided herein are compositions comprising panthenol-citrate containing materials. In particular, panthenol citrate compounds, oligomers, and polymers, and methods of use and synthesis thereof, are provided herein. Panthenol-citrate containing materials are a class of nontoxic, photoluminescent-chromophore-containing compounds, oligomers, and polymers with high absorption in the UVA and UVB range that can be incorporated and/or engineered into a variety of optically-active biomaterials (e.g., sunscreen products).

DISSOLVABLE MEDICAL DEVICE AND KIT FOR CORNEAL SURFACE PROTECTION

A dissolvable medical device for protecting a corneal surface and providing lubrication and hydration to the corneal surface during ophthalmic surgery comprising: a polymeric film has sufficient dimensions to substantially cover a cornea when applied to an eye, wherein the polymeric film comprising one or more mucoadhesive polymers. The polymeric film dissolves between 15 minutes to 120 minutes to release the mucoadhesive polymers after applying the polymeric film to the eye and the polymeric film provides more effective corneal surface protection relative to a saline treatment based on Mean Green Fluorescence Index test (demonstrates corneal damage) during a simulated surgery.
