  • Patent number: 7247270
    Abstract: The present invention is directed to an ophthalmic solution for soft contact lenses for controlled release of polyethers into an eye's tear film. Polyether components of the subject solution are released from the soft contact lens material matrix over long time periods to produce longer lasting wetting performance, improved lubricity, improved end-of-the-day comfort and reduced feeling of dryness from wearing contact lenses. The present invention also includes the use of cationic polyelectrolytes for controlling the swelling of hydrogel contact lenses typically caused by the absorption of high concentrations of polyethers.
