    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.
