CA 2231477

Contact lenses (8) are placed in a storage case (1) that contains hypotonic saline solution. The container (1) containing the lens and the solution is placed in a microwave oven and the hydrophillic contact lens (8) and the solution are both subject to direct microwave irradiation. During irradiation water vapour is lost from the solution which thereby goes from being hypotonic to isotonic.

Des lentilles cornéennes (8) sont placées dans un étui de rangement (1) qui contient une solution saline hypotonique. Le contenant (1) renfermant les lentilles et la solution est placé dans un four à micro-ondes. Les lentilles cornéennes hydrophiles (8) et la solution sont ensuite irradiées directement par les micro-ondes. Pendant l'irradiation, de la vapeur d'eau s'échappe de la solution qui devient alors isotonique.
