Abstract
Disclosed are co-polymers which are produced from reactive monomer mixtures and which have both high refractive index and a high Abbe number. These materials are well suited for use as implantable ophthalmic devices and have a refractive index which may be edited through application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses to allow a small incision size.
Claims25
A composition made by free radical polymerization of a reactive monomer mixture comprising:
- (a) at least one hydrophobic monomer;
- (b) at least one hydrophilic monomer that is a poly(ethylene glycol) methyl ether methacrylate;
- and
- (c) a tricyclo[5.2.1.02,6]decanedimethanol di(meth)acrylate cross-linking agent;
- wherein the composition exhibits a refractive index of at least 1.45 and an Abbe number of at least 39.
