  • Patent number: 12090156
    Abstract: In view of the problem that the current prevention and treatment manners for corneal neovascularization (CNV) may cause complications, the present disclosure provides an application of CB-839 in preparation of a drug for inhibiting CNV. The CB-839-loaded drug of the present disclosure can significantly inhibit CNV in mice and reduce the infiltration of inflammatory cells without obvious side effects, which makes up for the shortcoming of the prior art.

  • Patent number: 12076443
    Abstract: A preparation method of a nanozyme composite-based hybrid hydrogel eye drop includes synthesizing a tannin-coordinated silver/cobalt composite nanoparticle through a coordination reaction of cobalt chloride hexahydrate with ammonia water and an oxidation-reduction reaction of silver nitrate with tannin; and mixing the silver/cobalt composite nanoparticle with an acrylate-modified gelatin, conducting an ultrasonic treatment to allow complete dissolution, and irradiating a resulting mixture under ultraviolet (UV) light to obtain the nanozyme composite-based hybrid hydrogel eye drop. The preparation method of the present disclosure has simple operations and a short preparation time. The eye drop prepared by the preparation method shows a broad-spectrum bactericidal effect against a variety of bacteria and fungi, and has prominent preventive and therapeutic effects for bacterial and drug-resistant bacterial corneal infections.

  • Publication number: 20240226177
    Abstract: Retinal pigment epithelial cells can be used for replacing corneal endothelial cells, preventing and treating diseases or symptoms such as corneal endothelial functional decompensation. The retinal pigment epithelial cell transplantation, e.g., to the anterior chamber of an eye of the subject, can restore corneal transparency, reduce corneal thickness, reconstruct corneal endothelial barrier function, effectively treat corneal endothelial functional decompensation and corneal endothelial dysfunction.

  • Publication number: 20240156854
    Abstract: The present disclosure provides a methylcobalamin ophthalmic preparation and a preparation method and use thereof, belonging to the technical field of eye drops. The methylcobalamin ophthalmic preparation includes a methylcobalamin technical (TC) and proanthocyanidin, where the methylcobalamin TC and the proanthocyanidin have a mass ratio of (0.02-0.1):(0-0.5); and a dosage form of the methylcobalamin ophthalmic preparation is one or more of a drop, a hydrogel, and a liposome. In the present disclosure, the methylcobalamin is used as an active ingredient, and the proanthocyanidin is used as a synergist of the methylcobalamin; the methylcobalamin ophthalmic preparation can promote corneal nerve regeneration, accelerate corneal epithelial healing, and effectively inhibit corneal neovascularization to improve corneal perception.

  • Publication number: 20240123120
    Abstract: A corneal implant with adhesion-increase treatment is associated with a method for increasing the adhesion of the artificial corneal implant by an epoxy-amine ring-opening reaction of the polyamino high-molecular polymer and glycidyl methacrylate to obtain a methacrylate modified polyamino polymer. The method improves the adhesion and biocompatibility of the artificial corneal endothelial sheet by photo-initiated free radical polymerization reaction, and has a high oxygen permeability and a high adhesion. It can be used for treating patients with corneal endothelial decompensation, playing a barrier role to block aqueous humor, eliminating corneal edema, and reducing the risk of corneal graft detachment after surgery.

  • Publication number: 20230110021
    Abstract: 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.
