Abstract
Ophthalmic lenses, such as intraocular lenses, include cross-linked polymeric materials having a first constituent derived from a first monomeric component selected from the group consisting of acrylates, methacrylates and mixtures thereof, and a second constituent derived from a second component in an amount effective as a cross linker in the cross-linked polymeric material. The cross-linked polymeric material has branched chain alkyl groups, preferably included with at least a portion of the first monomeric component, in an amount effective to reduce the tackiness of the cross-linked polymeric material relative to a substantially identical cross-linked polymeric material without the branched chain alkyl groups.

A composition comprising a cross-linked polymeric material comprising a first constituent derived from a first monomeric component selected from the group consisting of acrylates having a branched chain alkyl group, methacrylates having a branched chain alkyl group and mixtures thereof, a second constituent derived from a second monomeric component in an amount effective as a cross linker in the cross-linked polymeric material and a third constituent derived from a third monomeric component, number of carbon atoms as the branched chain alkyl group of the first monomeric component.
