A biocompatible material which is the product of graft-copolymerization of a water-soluble vinyl and/or an acrylate monomer with a sorption complex of polysilicic acid and collagen that has been rid of pigments, glycoproteins and proteoglycans, or a product obtained by virtue of chemical destruction, with the aid of hydrofluoric acid, of the afore-mentioned product of graft-copolymerization, containing up to 25 mass percent of polysilicic acid (in terms of SiO.sub.2), up to 12 mass percent of protein, and maximum 1 10.sup.-6 mole/g of an anion of hydrofluoric and hydrofluoric acids, methods of making the same and products produced thereby.

Biocompatible polymer material and a process for producing same

Ophthalmologic collagen coverings derived from animal eyes and a process for preparing such coverings comprising treatment of a fibrous tunic of an animal eye with an alkali metal hydroxide in a saturated solution of a salt of an alkali metal, followed by neutralization, dissolution in an aqueous solution of an organic acid, purification of the resulting solution of collagen by dialysis against a buffer solution while bringing the solution of collagen to a pH of 4.5 to 7.5 and drying the thus-obtained solution of collagen simultaneously with shaping spherical coverings therefrom.
