Hycosan Extra has been formulated with 0.2% Sodium Hyaluronate. This increase in strength gives a solution which has four times more viscous than Hycosan Original, but still causes minimal blurring of vision. This increase in viscosity, which allows a subsequent increase in duration of action, makes Hycosan Extra ideal for more severe cases of Dry Eye.
