Abstract
The present invention provides copolymers made up of alkoxyalkyl methacrylate and/or alkoxyalkyl acrylate monomers in combination with one or more additional hydrophobic monomers. The copolymers may be used in the manufacture of intraocular lenses, including both the optic and haptic portions of the lenses. The present invention also provide methods for making intraocular lenses from the copolymers.
Claims23
A copolymer comprising monomeric subunits, wherein the monomeric subunits comprise:
- (a) one or more hydrophobic monomers, which can be the same or different;
- and
- (b) one or more alkoxyalkyl methacrylate monomers, which can be the same or different, and/or one or more atkoxyalkyl acrylate monomers, which can be the same or different,
- further wherein the primary monomeric subunits of the copolymer by weight are the one or more alkoxyalkyl methacrylate and/or the one or more alkoxyalkyl acrylate monomers and still further wherein the copolymer is optically clear and has an equilibrium water content of less than about 5 percent.
A copolymer comprising monomeric subunits, wherein the monomeric subunits comprise:
- (a) one or more hydrophobic monomers, which can be the same or different;
- and
- (b) one or more alkoxyalkyl methacrylate monomers, which can be the same or different,
- further wherein the primary monomeric subunits of the copolymer by weight are the one or more alkoxyalkyl methacrylate monomers and the one or more hydrophobic monomers combined with the one or more alkoxyalkyl methacrylate monomers make up at least about 75 percent of the copolymer by weight.
A copolymer comprising monomeric subunits, wherein the monomeric subunits comprise:
- (a) one or more hydrophobic monomers, which can be the same or different;
- and
- (b) one or more alkoxyalkyl methacrylate monomers, which can be the same or different, and/or one or more alkoxyalkyl acrylate monomers, which can be the same or different,
- further wherein the one or more alkoxyalkyl methacrylate monomers and/or the one or more atkoxyalkyl acrylate monomers comprise about 85 to about 97 percent of the copolymer by weight and the one or more hydrophobic monomers comprise about 3 to about 15 percent of the copolymer by weight.
