Abstract
The present invention, provides interpenetrating polymer network hydrogels that have high oxygen permeability, strength, water content, and resistance to protein adsorption. The hydrogels include two interpenetrating polymer networks. The first polymer network is based on a hydrophilic telechelic macromonomer. The second polymer network is based on a hydrophilic monomer. The hydrophilic monomer is polymerized and cross-linked to form the second polymer network in the presence of the first polymer network. The telechelic macromonomer preferably has a molecular weight of between about 575 Da and about 20,000 Da. Mixtures of molecular weights may also be used. In a preferred embodiment, the hydrophilic telechelic macromonomer is PEG-diacrylate or PEG-dimethacrylate and the hydrophilic monomer is an acrylic-based monomer. The material is designed to serve as a contact lens.
