摘要: The present invention provides a method for producing a silicone hydrogel having a high water content. The method comprises the following steps: (a) polymerizing a monomer mixture to form the silicone hydrogel, wherein the monomer mixture comprises at least one silicon-containing monomer and at least one ionic monomer; and (b) placing the silicone hydrogel in an alkaline solution for at least 20 minutes, wherein the alkaline solution has a pH not less than 7.5 and the ionic monomer is present in an amount not less than 0.7 wt % based on the total dry weight of the silicone hydrogel.
