Abstract
Infinite gradient refractive index ophthalmic devices and methods of making same. The method involves diffusing a monomer which polymerizes to a lower or higher corresponding opposite refractive index polymer into a lower or higher index polymer structure and polymerizing same to create the gradient structure. The resulting polymeric structure is used to manufacture ophthalmic devices, e.g., intraocular lenses.
