Abstract:
Compositions are provided herein comprising a base polymer having engrafted with a secondary polymeric matrix having hydrophilic and lubricious copolymer brushes. Each copolymer brush further comprises functional groups immobilized along the surface of the brush in a plurality of layers, the functional groups conferring hydrophilic and lubricious properties to the base polymer. These polymer compositions are useful for e.g., fabricating devices for delivery of intraocular lenses (IOLs) as well as improving the hydrophilic properties of contact lenses.

Claim (Index 4):
A base polymer comprising: a hydrophilic surface, said hydrophilic surface having a secondary engrafted surface matrix of hydrophilic and lubricious copolymers, the engraftment method further comprising the steps of:\n a. contacting the base polymer with a surface modifying composition having a hydrophilic reactive monomer, a lubricious reactive monomer and a solvent; and b. initiating radical formation in the base polymer, thereby engrafting the hydrophilic reactive monomers and the lubricious reactive monomers on to the surface of the base polymer.
