Is There Any Way To Keep My Contact Lenses From Expiring?

I have a couple packages of unopened monthly soft contact lenses that I bought last year. According to the unopened packages, they are about to expire.
From what I’ve gathered, it’s the saline solution in which these contacts are submerged that expire (and evaporate), not the actual lenses themselves. Would it be a feasible and/or safe way to extend the expiration of these lenses by opening them up and re-storing them in fresh saline liquid?
