The invention relates to a foldable intraocular lens material, characterized in that the material is comprised of the following repeat units [I], [II] and [III], and it comprises 60-80 wt.% of [I], 10-30 wt.% of [II] and 5-20 wt.% of [III], based on the total weight of a 100 wt.%. In formula (I), R<1> represents hydrogen atom or alkyl, R<2> represents alkylene which can be substituted by hydroxy group, in addition, the alkylene chain can contain oxygen atom also. In formula (II), R<3> represents formula (IIa), (IIb), (IIc), in which R<5>, R<6>, R<7> and R<8> represent hydrogen atom or alkyl respectively, m, n, p and q are integers from 1-4 or a single bond and R<4> is a hydrogen atom or alkyl. In formula (III), R<9> is a hydrogen atom or alkyl and R<10> is alkyl. |
