The article presents the results of application of the developed hydrogel as a Lucentis carrier in glaucoma surgeries. Experimental studies were carried out on 12 (12 eyes) healthy rabbits. In vitro and in vivo experiments proved that Lucentis, introduced in 0.1 ml of hydrogel drainage into glaucoma surgery zone, was being released gradually and inhibited the proliferation of connective tissue. The desirable concentration of Lucentis was found to be 0.02 ml in 0.1 ml of gel.
Key words: hydrogels, Lucentis, primary open-angle and refractory glaucoma.
