Methods and systems for leaching silicone hydrogel ophthalmic lenses

A method for removing unreacted components and diluents from an ophthalmic lens comprising silicone, the method comprising:

• exposing said ophthalmic lens to a first aqueous solution comprising about 5% or more of a first leaching agent comprising one or more of:
• E12E10, SDS, EH-5, PPG 425, EtOH, and IPA, and wherein the first aqueous solution additionally comprises 5% or more of a second leaching agent comprising SCAW;
• heating said first aqueous solution to which the ophthalmic lens is exposed;
• and
• rinsing said ophthalmic lens through contact with a second aqueous solution until said lens comprises a level of unreacted components and diluents that is below a predetermined threshold.
