Abstract
Hydrophilic, arylsiloxy-containing macromonomers have at least a terminal hydrophilic group attached to an arylsiloxy group. The aryl groups attached to siloxy groups can be substituted with other hydrophilic groups. Polymers comprising such hydrophilic, arylsiloxy-containing macromonomers avoid or reduce the risk of forming vacuoles of absorbed water. Furthermore, such polymers have high refractive index, and, thus, are advantageously used for making ophthalmic devices, such as intraocular lenses, contact lenses, corneal rings, corneal inlays, and keratoprostheses.
