Abstract
Described herein are methods of stereolithographically printing intraocular devices, in particular intraocular lenses, as well as stereolithographic compositions for use therein. The stereolithography composition may comprise: a photoinitiator; a monofunctional aryl acrylate monomer, wherein the acrylate group of the monofunctional aryl acrylate monomer is of the formula -0-(C═0)-CH═CH2; and a multifunctional methacrylate or acrylate cross-linker, wherein the monofunctional aryl acrylate monomer is present in the composition in a greater amount than the multifunctional methacrylate or acrylate cross-linker.
Claims20
A stereolithography composition for printing intraocular devices, the stereolithography composition comprising:
- a photoinitiator;
- a monofunctional aryl acrylate monomer, wherein the acrylate group of the monofunctional aryl acrylate monomer is of the formula —O—(C═O)—CH═CH2;
- and
- a multifunctional methacrylate or acrylate cross-linker,
- wherein the monofunctional aryl acrylate monomer is present in the composition in a greater amount than the multifunctional methacrylate or acrylate cross-linker.
A method of producing intraocular devices, the method comprising:
- stereolithographically printing intraocular devices using a stereolithography composition comprising:
- a photoinitiator;
- a monofunctional aryl acrylate monomer, wherein the acrylate group of the monofunctional aryl acrylate monomer is of the formula —O—(C═O)—CH═CH2;
- and
- a multifunctional methacrylate or acrylate cross-linker, and
- wherein the monofunctional aryl acrylate monomer is present in the composition in a greater amount than the multifunctional methacrylate or acrylate cross-linker;
- washing the printed intraocular device;
- and
- applying heat and irradiation to fully cure the stereolithography composition.
