Abstract
Acrylate-acrylamide copolymers are disclosed. They are rigid and glassy in dry state at room temperature (from about 23° C. to about 28° C.), but are soft and very deformable and have a high refractive index, a high glistening resistance and a low aging-related surface light scattering in fully hydrated state. They are particularly suitable for making wet-packed intraocular lenses (IOLs) which can be delivered through sub 2.0 mm incisions.
