摘要:
A process for removing extractables from biomedical devices, particularly ophthalmic biomedical devices, involves contacting the device with a mixture of first and second extractants. The first extractant is an organic compound having a flash point above 38° C., and the second extractant is an organic compound having a flash point below 38° C.
摘要:
A polysiloxane comprises diaryl, dialkyl, and arylalkyl siloxane units, and further has at least a functional group. Such polysiloxane can be further copolymerized with an additional monomer to produce polymeric compositions suitable for making ophthalmic devices. The additional monomer can be selected to produce desirable properties for ophthalmic applications, such as high refractive index and/or high elongation.
摘要:
Provided are novel reactive functionalized fumaric- and itaconic-containing prepolymers and compositions comprising the prepolymers used in the manufacture of medical devices. The prepolymers can be used to provide surface modified contact lenses formed from one or more fumaric- or itaconic-containing prepolymers having reactive functionality that is complimentary to reactive, hydrophilic polymers.

摘要:
Relatively high refractive index polymeric compositions and ophthalmic devices such as for example intraocular lenses and corneal inlays made therefrom are described herein. The preferred polymeric compositions are produced through the copolymerization of one or more aromatic-substituted polysiloxane prepolymers with one or more aro matic monomers, alkylated monomers or hydrophilic monomers.

摘要:
A process for producing polysiloxane prepolymers of improved homogeneity for use in the production of relatively high refractive index polymeric compositions is described herein. Polymeric compositions so produced are useful in the production of ophthalmic devices such as for example intraocular lenses and corneal inlays. The preferred polymeric compositions are produced through the copolymerization of one or more polysiloxane prepolymers with hydrosilane-containing polysiloxanes.
