Zusammenfassung:	FIELD: medicine. SUBSTANCE: liquid photohardened material is poured into casting mould and irradiated by ultraviolet light. Then unhardened photomaterial is removed, and annealing is performed, after which artificial lenses of eye are placed in closed vessel filled with isopropyl alcohol at temperature from minus 20 to plus 12 C and kept them therein from 3 to 24 h. This done, thermovacuum drying is performed at temperature of 40-70 C for 1-6 h. EFFECT: manufacture of artificial lenses characterized lower traumatization and higher elasticity. 7 dwg, 2 tbl, 5 ex
