摘要：
Ophthalmic devices are provided based on an interpenetrating (IPN) double network hydrogel of a first network physically entangled with a second network. The first network is an entangled network of self-linked hydrophilic telechelic macromonomers and hydrophobic moieties. The second network is a hydrophilic network of crosslinked polyacrylic acid. The IPN double network hydrogels including the hydrophobic moieties are characterized by being optically clear and having refractive indices above 1.34.
