ABSTRACT:
Packaging systems for storing ophthalmic devices such as contact lenses and to methods for packaging such ophthalmic devices with solutions to improve the comfort of the lenses during wear are disclosed. A packaging system includes an ophthalmic device stored in an aqueous packaging solution comprising a substantially water-soluble silicone-containing surfactant. Such solutions are retained on the surface of an unused lens for extended periods of time, resulting in surface modification that persists in the eye, which may provide significant improvement in the wetting properties of fresh contact lenses used for the first time and, moreover, even several hours after lens insertion, preventing dryness and improving lubricity.
