  • 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.

  • Patent number: 11779490
    Abstract: A minimally invasive ab interno triple surgery for open-angle glaucoma comprises knotting and fixing a suture at the head end of an optical fiber catheter; performing miosis with carbachol, injecting the viscoelastic into the anterior chamber, making a lateral incision at the infratemporal corneal limbus, and placing the optical fiber catheter; cutting the Schlemm's canal on the nasal side of the anterior chamber, inserting an optical fiber into the incision on the Schlemm's canal, and cutting off the suture; injecting the viscoelastic to expand while retreating the microcatheter, and regularly injecting the viscoelastic; making a conjunctival flap on the eye and nose side, performing anterior chamber paracentesis, clamping out the suture using intraocular microforceps, and knotting in the sclera tunnel; and suturing the conjunctival flap using the suture, coating the eyes, and covering the eyes with gauze to finish the surgery.
