FIELD: medical engineering.
SUBSTANCE: implant is manufactured from porous polytetrafluoroethylene having structure composed of polymer elements and empty space elements with elements joined into three-dimensional network possessing empty space element volume share of 15-40%, specific space element surface of 0.25-0.55 mcm2/mcm3, mean distance between empty spaces in a volume of 25-50 mcm and mean spatial chord of 8-25 mcm. The supporting plate is manufactured as convexo-concave lens having curvature radius of 7,0-10,0 mm. Cylindrical hole is optionally available in lens center.
EFFECT: low costs and improved implant production; improved implantability characteristics.
