Abstract
A method of preparing a water extractable silicon-containing biomedical device is disclosed. The method involves curing a monomer mixture comprising one or more silicon-containing biomedical device-forming monomers in the presence of a diluent to produce a silicon-containing biomedical device; wherein the diluent comprises a boric acid ester of a C1 to C8 monohydric alcohol.
Claims28
A method of preparing a water extractable silicon-containing biomedical device comprising the step of curing a monomer mixture comprising one or more silicon-containing biomedical device-forming monomers in the presence of a diluent to produce a silicon-containing biomedical device;
- wherein the diluent comprises a boric acid ester of a C1 to C8 monohydric alcohol.
The method of claim 16, wherein the silicon-containing biomedical device is a silicon hydrogel.
A method for dry releasing a silicon-containing biomedical device from a mold, the method comprising the steps of:
- (a) curing a monomer mixture in a mold under conditions sufficient to polymerize the monomer mixture to produce a water extractable silicon-containing biomedical device, wherein the monomer mixture comprises one or more silicon-containing biomedical device-forming monomers and a diluent;
- wherein the diluent comprises a boric acid ester of a C1 to C8 monohydric alcohol;
- and
- (b) dry releasing the silicon-containing biomedical device from the mold.
