Celluvisc eye drops are used as an eye lubricant for the treatment of dry eyes. ** Key Benefits:** - Carmellose acts as artificial tears - Treats the symptoms of dry eye - Treats soreness, burning, irritation, and dryness - Handy single-use vials The active ingredient carmellose sodium, a type of medicine known as an eye lubricant, helps to treat the symptoms of dry eye, caused by your eye not producing enough tears to keep the eye wet. Carmellose is a synthetic polymer that forms a viscous eye gel. It produces a transparent, lubricating, and moistening film on the surface of the eye and is used as artificial tears. Carmellose clings to the surface of the eye and is therefore not washed out of the eye as quickly as some other lubricating eye drops. Celluvisc eye drops are available in single-use vials with a twist-off seal. Once the seal is broken the drops must be used or thrown away.
