The study of reasons of unsatisfactory eye prosthesis has shown that after insertion of cosmetic eye prosthesis into the conjunctival cavity in the majority of patients an inflammatory process develops which often goes on for several years. Discomfort and inflammation are mainly caused by a shift in acid-alkali balance in the conjunctival cavity, protein, fat and calcium deposits on the surface of prosthesis. The available agents of caring conjunctival cavity and prosthesis do not permit to fully clean prosthesis and to restore acid-alkali balance in cavity being equipped with prosthetic appliance. The authors offer new methods of taking care of prosthesis and conjunctival cavity making it possible to improve convenience of wearing eye prostheses, to disinfect them efficiently, clean them and prolong their service life.
