VISMED® is a hypotonic aqueous solution of sodium hyaluronate (SH) which contains a number of important ions also found in natural tears, and, as such, is very close in characteristics to the natural tear film. The inclusion of both SH and essential ions in VISMED® is possible because of its unique patented formulation with citrate. With this special formulation, VISMED® offers patients with sensations of ocular dryness an unmatched combination of symptomatic relief and comfort. VISMED® is suitable for all types of contact lenses.
