摘要:
Systems and methods for producing silicone hydrogel contact lenses are described. Certain of the present systems include a contact lens mold forming station, a station for filling a contact lens mold section with a lens precursor composition and for placing a second mold section on the filled mold section to form a contact lens mold assembly, a curing station for forming a contact lens, a mold assembly separation station, and an extraction/hydration station. Certain of the present methods include forming a plurality of mold sections, placing a lens precursor composition on a surface of a first mold section, placing a second mold section on the first mold section, polymerizing the lens precursor composition, separating the first and second mold sections, removing the silicone hydrogel contact lens from one of the mold sections, extracting extractable components from the contact lens, and hydrating the contact lens.
