CA 2384652
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.
Cette invention se rapporte à un procédé servant à traiter des dispositifs biomédicaux, notamment des lentilles de contact, et consistant à mettre des dispositifs polymères contenant des matières extractibles en contact avec un solvant qui dissout et par conséquent élimine ces matières extractibles du dispositif, à traiter ce solvant pour éliminer les matières extractibles du solvant, en vue de purifier le solvant, et à utiliser ce solvant purifié pour éliminer les matières extractibles additionnelles desdits dispositifs polymères.
