Abstract

Disclosed are high refractive index, hydrophobic, acrylic materials. These materials have both high refractive index and a high Abbe number. This combination means the materials have a low refractive index dispersion and thus are especially suitable for use as intraocular lens materials. The materials are also suitable for use in other implantable ophthalmic devices, such as keratoprostheses, corneal rings, corneal implants, and corneal inlays.

First claim

I claim:

1. An ophthalmic device material made by polymerizing a mixture of monomers wherein the mixture comprises:
a) 77-82 wt. % 2-cyclohexylethyl acrylate;
b) 16-19 wt. % 2-hydroxyethyl methacrylate; and
c) 1.4-1.8 wt. % neopentyl glycol diacrylate;
wherein the ophthalmic device material has a refractive index of 1.48-1.50, an Abbe number greater than 52, a Tg<10° C., and an equilibrium water content less than 2%.
