    Abstract: Polyethylene oxide (PEO) coatings providing improved biocompatibility for implantable medical devices are disclosed. The PEO coatings comprise functionalized, end-capped PEO which is attached at one end to the medical device. The PEO compounds are then cross-linked by 1) exposure to a high energy source for a time sufficient to cause the PEO compounds to form a cross-linked, insoluble network or 2) by reacting the free functionalized ends of a sufficient number of bound PEO compounds with a crosslinking agent whose functional groups are reactive toward the bound PEO chain's functionalized ends. These PEO coatings are able to survive ethylene oxide sterilization procedures with minimal loss of protein or cell repulsion ability.

    Abstract: High refractive index copolymers suitable for use in ophthalmic devices are disclosed. The copolymers comprise a) two or more monomers of structure (I), wherein X is H or CH3; m is 0-10; Y is nothing, 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 H, 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 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)-).
