Abstract
Disclosed are hydrophobic, acrylic materials having both high refractive index and a high Abbe number. The materials may have an internal wetting agent, 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.
Claims21
A composition made by free radical polymerization of a reactive monomer mixture comprising:
- a) at least one hydrophobic monomer,
- b) at least one hydroxyl-containing monomer,
- c) at least one tricyclo[5.2.1.02.6]decanedimethanol di(meth)acrylate;
- and
- d) at least one polyamide,
- wherein the reactive monomer mixture comprises the polyamide in an amount of about 0.10 to about 5.0 weight percent.
