Abstract

An antimicrobial polymer for use in an ophthalmic implant, includes at least one antimicrobial monomer; and at least one other monomer selected from an acrylic, silicone, vinyl and collagen monomer.

Claims (21)

1. An ophthalmic implant comprising an antimicrobial polymer, comprising:

at least one antimicrobial monomer, wherein the antimicrobial monomer is a quaternary ammonium salt based monomer selected from 1-[12-(methacryloyloxy)dodecyl]-pyridinium bromide (MDPB), methacryloxylethyl cetyl dimethyl ammonium chloride (DMAE-CB), 2-methacryloxyethyl dodecyl methyl ammonium bromide (MAE-DB), 2-methacryloxyethyl hexadecyl methyl ammonium bromide (MAE-HB), and bis(2-methacryloxyethyl) dimethyl ammonium bromide (IDMA-1); and,

at least one other monomer selected from an acrylic, vinyl and collagen monomer; and,

wherein the ophthalmic implant is an intraocular lens.

2. The ophthalmic implant according to claim 1 , wherein the antimicrobial polymer is clear, opaque, or translucent.

3. The ophthalmic implant according to claim 1 , wherein the antimicrobial polymer is reversibly deformable.

4. The ophthalmic implant according to claim 1 , wherein the at least one other monomer is an acrylic monomer selected from methyl acrylate (MA) and methyl methacrylate (MMA), or a vinyl monomer selected from a vinyl carbonate and a vinyl carbamate.

5. An ophthalmic implant comprising an antimicrobial polymer, comprising:

at least one antimicrobial monomer, wherein the antimicrobial monomer is a quaternary ammonium salt based monomer selected from 1-[12-(methacryloyloxy)dodecyl]-pyridinium bromide (MDPB), methacryloxylethyl cetyl dimethyl ammonium chloride (DMAE-CB), 2-methacryloxyethyl dodecyl methyl ammonium bromide (MAE-DB), 2-methacryloxyethyl hexadecyl methyl ammonium bromide (MAE-HB), and bis(2-methacryloxyethyl) dimethyl ammonium bromide (IDMA-1); and,

at least one other monomer selected from an acrylic, vinyl and collagen monomer, wherein the antimicrobial polymer is for use in an ophthalmic implant; and,

wherein the ophthalmic implant is an intraocular lens.

6. The ophthalmic implant according to claim 5 , wherein the at least one other monomer is an acrylic monomer selected from methyl acrylate (MA) and methyl methacrylate (MMA), or a vinyl monomer selected from a vinyl carbonate and a vinyl carbamate.

7. The ophthalmic implant according to claim 5 , wherein the antimicrobial polymer is clear, opaque, or translucent.

8. The ophthalmic implant according to claim 5 , wherein the antimicrobial polymer is reversibly deformable.

9. An ophthalmic implant comprising an antimicrobial polymer, comprising:

at least one antimicrobial monomer, wherein the antimicrobial monomer is a quaternary ammonium salt based monomer selected from 1-[12-(methacryloyloxy)dodecyl]-pyridinium bromide (MDPB), methacryloxylethyl cetyl dimethyl ammonium chloride (DMAE-CB), 2-methacryloxyethyl dodecyl methyl ammonium bromide (MAE-DB), 2-methacryloxyethyl hexadecyl methyl ammonium bromide (MAE-HB), and bis(2-methacryloxyethyl) dimethyl ammonium bromide (IDMA-1); and,

and at least one other monomer selected from an acrylic, vinyl and collagen monomer, wherein the antimicrobial polymer is formed into an ophthalmic implant; and,

wherein the ophthalmic implant is an intraocular lens.

10. The ophthalmic implant according to claim 9 , wherein the at least one other monomer is an acrylic monomer selected from methyl acrylate (MA) and methyl methacrylate (MMA) or a vinyl monomer selected from a vinyl carbonate and a vinyl carbamate.

11. The ophthalmic implant according to claim 9 , wherein the antimicrobial polymer is clear, opaque, or translucent.

12. The ophthalmic implant according to claim 9 , wherein the antimicrobial polymer is reversibly deformable.
