The present invention is directed to a biocompatible copolymer material for manufacturing optical clear hydrophobic ophthalmologic implant, formed by polymerization of a mixture comprising:a) 35-70 wt,% of urethane di(meth)acrylate oligomer with terminal (meth)acrylate groups being prepared form the components (I) (meth)acrylate (II) diisocyanate and (III) polyol and having the following structure:hydroxy(meth)acrylate' - [(diisocyanate') -POLYOL- (diisocyanate")] - hydroxy(meth)acylate", wherein one isocyanate group of diisocyanate' and diisocyanate", respectively, is reacted with the hydroxyl group of the hydroxy(meth)acrylate' and hydroxy(meth)acrylate", respectively under formation of an urethane group,and wherein the other one of the isocyanate groups of diisocyanate' and diisocyanate", respectively, is reacted with a hydroxyl group of the polyol under formation of an urethane group,b) 30-65 wt.% of component b) being selected from the group (meth)acrylate monomers of the group of alkyl (meth)acrylates, aryl (meth)acrylates, alicyclic (meth)acrylates, fluorinated (meth)acrylates, silicon containing (meth)acrylates, any of aromatic or alkyl esters of the unsaturated non methacrylic carboxylic acids and mixtures thereof,c) UV-light absorbing compound, andd) polymerization initiator.wherein the mentioned biocompatible copolymer material for manufacturing hydrophobic ophthalmologic implant are hydrophobic with equilibrium water content at 37°C of less than 3.0%. Furthermore, the invention is directed to an ophthalmologic implant being made from said copolymer material.
