Abstract

The ophthalmic device comprises a high refractive index copolymer having a glass transition temperature less than 37oC and an elongation of at least 150%, wherein the copolymer comprises: a) two or more monomers of the structure (I), wherein: X is H or CH----3; m is 0-10; Y is absent or is O, S, or NR wherein R is H, CH3, CnH2n+1 (n=1-10), iso-OC3H7, C6H5, or CH2C6H5; Ar is any aromatic ring which can be unsubstituted or substituted with CH3, C2H5, n-C3H7, iso-C3H7, OCH3, C6H11, Cl, Br, C6H5, or CH2C6H5; and b) a total of about 5 mole % or less of one or more monomers of the structure (II), wherein: X is H or CH3; W is -CH3 or (CH2=C(-X)-C(=O)-); and n is such that the weight average molecular weight is approximately 600-1000 if W is CH3 and approximately 400-1000 if W is (CH2=C(-X)-C(=O)-) C (=O)-). If none of the monomers of formula (II) are chosen so that W is (CH2=C(-X)-C(=O)-), the copolymer also comprises a cross-linking agent.
