The synthetic hydroxyapatite made in Russia was applied as an insert-implant to 4 rabbits (6 eyes, 6 eviscerations). These included 2 implants having a porosity of 40% and a pore size of 0.03-1.5 microm and 2 with a porosity of 63% and a pore size of 0.05-3.0 microm. The hydroxyapatite that is made in Russian and that has preferably a porosity of 40% and a pore size of 0.03-1.5 microm can be successfully used to make a locomotor stump after removal of the eyeball. The hydroxyapatite having these parameters more rapidly intergrows around the periphery with fibrovascular tissue and its vascular components mainly reduce by month 8. Our data suggest that the synthetic hydroxyapatite made in Russia may be used in ophthalmological care.

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.
