ABSTRACT:
This invention provides a method of altering the water content of a hydrogel comprising treatment of said hydrogel with a liquid dehydrating composition. There is further provided a method of altering the water content of a hydrogel-containing medical device. The medical devices of the present invention comprise a hydrogel having a water level ex vivo lower than the thermodynamic equilibrium water level when in vivo. These medical devices comprise a hydrogel contacted with a liquid dehydrating agent, wherein said medical device has a lower water level ex vivo than the thermodynamic equilibrium water level when the medical device is in vivo.
