A METHOD FOR OBTAINING ION-EXCHANGE POLYMERIC HYDROGELS FOR EYE TREATMENT AND HYDROGEL LENSES THEREOF

The present invention could be used in medicine and relates to a method of producing ion-exchange polymeric hydrogels for eye treatment, which includes monomer copolymerization under ionizing radiation in presence of linking agent and ionites, when copolymerization is carried out gradually to obtain a prepolymer of desired viscosity for filling lens forms, and ionites introduction in the form of finely dispersed powder, filing the hydrogel into lens forms and subsequent copolymerization till an adequate ionizing dosage is performed providing a gel suitable for lenses formation, characterized in that the gel is also filled with pharmaceutically active agent in the form of finely dispersed powder prior to ionite introduction, and the size of particles of PAA is lower that the size of ionite particles. The present invention also relates to therapeutic hydrogel lenses produced in accordance with the above-mentioned method.

Compounds for use in wound healing and angiogenesis

HYDROGEL RETINAL TAMPONADE AGENT

A hydrogel retinal tamponade agent is disclosed herein. The disclosed hydrogel tamponade agent acts as a temporary barrier to fluid flow into the subretinal space and obviates the need to use intraocular gases or silicone oil as a retinal tamponade agent in a retinal detachment repair procedure. The hydrogel tamponade agent remains in place after a permanent seal is achieved and is slowly resorbed. The hydrogel tamponade agent is preferably biocompatible.
