A process for impregnating a medical device made from a water absorbable polymer material, e.g., a hydrogel, with a medical compound having low solubility in aqueous solutions, e.g., an antiseptic or radiopaque compound, is disclosed. The device is first infiltrated with an aqueous solution containing a first water soluble, ionizable compound, and subsequently infiltrated with an aqueous solution containing a second water soluble, ionizable compound. The ionizable compounds are selected such that they react after mutual contact to form the medical compound in-situ within the device. |
