Abstract
A process for treating biomedical devices, especially contact lenses, involves contacting polymeric devices containing extractables with a solvent that dissolves and thereby removes the extractables from the device, treating the solvent to remove extractables from the solvent, thereby purifying the solvent, and using the purified solvent to remove additional extractables from polymeric devices.
