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.
