Abstract

Disclosed are co-polymers which are produced from reactive monomer mixtures and which have both high refractive index and a high Abbe number. These materials 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.

First claim

We claim:

1 . A composition made by free radical polymerization of a reactive monomer mixture comprising:
a. at least one cycloaliphatic (meth)acrylate; b. at least one aliphatic (meth)acrylate; and c. at least one cross-linking agent;
wherein the composition exhibits a refractive index of at least 1.45 and an Abbe number of at least 39.

2 . The composition of claim 1 , wherein the cycloaliphatic (meth)acrylate comprises a cycloaliphatic group having between one and four cycloaliphatic rings.

3 . The composition of claim 1 , wherein the cycloaliphatic (meth)acrylate is a poly(ethylene glycol) methyl ether methacrylate

4 . The composition of claim 1 , wherein the cycloaliphatic (meth)acrylate is selected from cyclohexyl acrylate, cyclohexylmethyl acrylate, 2-cyclohexylethylacrylate, 3-cyclohexylpropylacrylate, ethylene glycol dicyclopentenyl ether acrylate, and any combination thereof.

5 . The composition of claim 1 , wherein the aliphatic (meth)acrylate comprises a linear or branched alkyl group containing between 1 and 25 carbon atoms, or between 4 and 8 carbon atoms.

6 . The composition of claim 1 , wherein the cross-linking agent is a non-cycloaliphatic cross-linking agent selected from ethylene glycol di(meth)acrylate, diethylene glycol di(meth)acrylate, triethylene glycol di(meth)acrylate, tetraethylene glycol di(meth)acrylate, trimethylolpropane tri(meth)acrylate, glycerol tri(meth)acrylate, triallyl cyanurate, methylene bis(meth)acrylamide, poly(ethylene glycol) di(meth)acrylate, bis(2-hydropropyl (meth)acrylate) terminated polydimethylsiloxanes, and any combination thereof.

7 . The composition of claim 1 , wherein the cross-linking agent is a cycloaliphatic cross-linking agent comprising a cycloaliphatic group having between one and four cycloaliphatic rings.

8 . The composition of claim 7 , wherein the cycloaliphatic cross-linking agent is tricyclo[5.2.1.0 2,6 ]decanedimethanol di(meth)acrylate.

9 . The composition of claim 1 , further comprising an aromatic (meth)acrylate or a hydroxyalkyl (meth)acrylate.

12 . The composition of claim 1 , further comprising at least one UV/HEV absorbing compound in the reactive monomer mixture, wherein the UV/HEV absorbing compound is selected from 2-(2′-hydroxy-5-methacrylyloxyethylphenyl)-2H-benzotriazole, 2-(2-cyano-2-(9H-thioxanthen-9-ylidene)acetamido)ethyl methacrylate, 2-(2-cyano-2-(9H-xanthen-9-ylidene)acetamido)ethyl methacrylate, 2-(2-cyano-2-(10-methylacridin-9(10H)-ylidene)acetamido)ethyl methacrylate, 3-(3-(tert-butyl)-5-(5-chloro-2H-benzo[d][1,2,3]triazol-2-yl)-4-hydroxyphenyl)propyl methacrylate, a compound of formula II:

wherein:
