Abstract

The present invention relates to ophthalmic solutions and devices comprising at least one water soluble polymer having a molecular weight of at least about 500,000 Daltons and comprising linear or branched polyether pendant groups having a molecular weight of at least about 300.

First claim

We claim:

1. An ophthalmic device comprising at least one water soluble polymer having a molecular weight of at least about 500,000 Daltons and comprising linear or branched polyether pendant groups having a molecular weight of at least about 300, wherein said polyether pendant groups are derived from monomers of the Formula I
A-[(CZ p H q ) y —O] n —CH m —X 3-m

wherein n is 7 or greater; Z is a C 1 -C 6 substituted or unsubstituted alkyl group, q is 0, 1 or 2 and p is 2-q, y is 2 to 4, m is 1 or 2; A is any free radical polymerizable group and X is a substituent independently selected from the group consisting of H, hydroxyl, unsubstituted straight or branched alkyl groups, substituted straight or branched alkyl groups, substituted and un substituted amines, substituted and un substituted amides, mercaptans, ethers and esters; and wherein the water soluble polymer further comprises at least one second pendant group.

2. The device of claim 1 wherein X is selected from substituted or unsubstituted straight or branched C1-16 alkyl groups.

3. The device of claim 2 wherein X is selected from substituted or unsubstituted straight or branched C1-12 alkyl groups.

4. The device of claim 2 wherein said alkyl group is substituted with a group selected from the group consisting of carboxylic acids, esters, acyl halides, amines, amides, ketones, aldehydes, halides, sulfides, mercaptans, quartenary ammonium salts and combinations thereof.

5. The device of claim 2 wherein n is an integer of between 7 to 50.

6. The device of claim 2 wherein n is an integer of between 7 to 40.

7. The device of claim 1 wherein said polymer comprises at least about 20% of backbone units have a pendant group bound thereto.

8. The device of claim 1 wherein said polymer comprises at least about 30% of backbone units have a pendant group bound thereto.

9. The device of claim 1 wherein at least about 20% of said pendant groups are polyether pendant groups of Formula I.

10. The device of claim 1 wherein at least about 60% of said pendant groups are polyether pendant groups of Formula I.

11. The device of claim 1 wherein at least about 75% of said pendant groups are polyether pendant groups of Formula I.

12. The device of claim 1 wherein said at least one second pendant group is selected from the group consisting of silicones, sugars, carbohydrates, polyethers, amides, lactams, sulfonic acids, sulfonates, amines, hydroxyls, ethers, esters, aldehydes, ketones, amino acids, methacrylated long chain hydrocarbons, polymerizable ionic compounds, reactive latent compounds which may be converted to ionic groups after the water soluble polymer is polymerized and combinations thereof.

13. The device of claim 1 wherein said at least one second pendant group is selected from the group consisting of amides, lactams, glycosylated materials, polymerizable ionic compounds and combinations thereof.

14. The device of claim 1 wherein said at least one second pendant group is selected from the group consisting lauryl methacrylate, butyl methacrylate, isopropyl methacrylate, methyl methacrylate, phenyl methacrylate, hydroxyethyl methacrylate, methacrylic acid, glycerol monomethacrylate, hydroxyethyl methacrylamide, 2-(-4-morpholinyl)ethyl methacrylate, morpholinyl methacrylamide, 2-(N,N-dimethylamino)ethyl methacrylate, dimethylacrylamide, N-vinyl pyrrolidone, N-vinyl-N-methylacetamide, styrene sulfonate, sodium 2-acrylamido-2-methyl-1-propanesulfonate, sulfopropylacrylamide and combinations thereof.
