HORUS PHARMA Vismed Eye lubricant Hypo-osmolar ophthalmic solution at 150 mOsmol/l without preservative Sodium hyaluronate: 0.18%. Medical device 20 single doses of 0.3ml VISMED® contains sodium hyaluronate, a natural polymer also present in the structures of the human eye. The particular physical characteristics of sodium hyaluronate give VISMED® its viscoelastic and water retention properties. VISMED® thus forms a stable film on the surface of the eye which is eliminated very slowly by blinking. VISMED® thus combines a long-lasting effect with maximum comfort. Thanks to its special composition, VISMED® is very well tolerated. VISMED® does not contain preservatives.
