ABSTRACT:
Disclosed are methods for extracting leachable materials from a hydratable polymer by incorporation of an adsorbent into the solution employed to effect extraction. Suitable adsorbents are characterized as having a higher affinity for the leachable materials than either the hydratable polymer or the solvent employed in the solution. Also disclosed are sealed packages comprising an aqueous solution, an adsorbent and a hydratable polymer in the form of an ophthalmic device.
