First claim
Opening claim text (preview).
The invention claimed is: 1. An intraocular lens material comprising: an aromatic ring-containing acrylate structural unit; an alkoxyalkyl methacrylate structural unit including an alkoxyalkyl group having 4 or less carbon atoms; an alkyl acrylate structural unit including an alkyl group having 1 to 20 carbon atoms, a hydrophilic structural unit based on a hydrophilic monomer; a cross-linking structural unit based on a cross-linkable monomer, wherein the aromatic ring-containing acrylate structural unit is phenoxyethyl acrylate structural unit, the alkoxyalkyl methacrylate structural unit is an ethoxyethyl methacrylate structural unit, the alkyl acrylate structural unit is an ethyl acrylate structural unit, and a base material consists of the aromatic ring-containing acrylate structural unit, the alkoxyalkyl methacrylate structural unit and the alkyl acrylate structural unit, and the base material include one kind of the aromatic ring-containing monomer. 2. The intraocular lens material according to claim 1 , wherein the alkoxyalkyl methacrylate structural unit is included in an amount within the range of from 10 parts by mass to 70 parts by mass inclusive based on 100 parts by mass of the total amount of the base material. 3. The intraocular lens material according to claim 1 , wherein the alkoxyalkyl methacrylate structural unit is included in an amount within the range of from 10 parts by mass to 40 parts by mass inclusive based on 100 parts by mass of the total amount of the base material. 4. The intraocular lens material according to claim 1 , wherein the hydrophilic structural unit is included in an amount within the range of from 15 parts by mass to 35 parts by mass inclusive by the outside ratio based on 100 parts by mass of the total amount of the base material. 5. The intraocular lens material according to claim 1 , wherein the cross-linking structural unit is included in an amount within the range of from 2 parts by mass to 4 parts by mass inclusive by the outside ratio based on 100 parts by mass of the total amount of the base material. 6. The intraocular lens material according to claim 1 , wherein the alkyl acrylate structural unit is included in an amount within the range of from 10 parts by mass to 35 parts by mass inclusive based on 100 parts by mass of the total amount of the base material. 7. The intraocular lens material according to claim 1 , wherein the aromatic ring-containing acrylate structural unit is included in an amount within the range of from 15 parts by mass to 80 parts by mass inclusive based on 100 parts by mass of the total amount of the base material. 8. The intraocular lens material according to claim 1 , wherein the hydrophilic structural unit is a hydroxyethyl methacrylate structural unit. 9. The intraocular lens material according to claim 1 , wherein the cross-linking structural unit is a butanediol diacrylate structural unit. 10. The intraocular lens material according to claim 1 , wherein the aromatic ring-containing acrylate structural unit is included in an amount within the range of from 30 parts by mass to 80 parts by mass inclusive based on 100 parts by mass of the total amount of the base material, the alkoxyalkyl methacrylate structural unit is included in an amount within the range of from 10 parts by mass to 40 parts by mass inclusive based on 100 parts by mass of the total amount of the base material, the alkyl acrylate structural unit is included in an amount within the range of from 10 parts by mass to 35 parts by mass inclusive based on 100 parts by mass of the total amount of the base material.
