Cationorm – a preservative-free dry eye treatment


Cationorm (cationic nanoemulsion) is a preservative-free moisturizing and lubricating emulsion that protects the surface of the eye, reducing the discomfort and irritation of persistent dry eyes caused by prolonged contact lens wear or environmental conditions.1

The therapy’s triple action repairs the lipid layer to reduce evaporation, lubricates and stabilizes the tear film; restores the moisture balance in the muco-aqueous layer of the tear film; and is positively attracted to the ocular surface, to provide long-lasting protection.2-5

Cationorm is suitable for use with contact lenses and is easily administered via a preservative-free multi-dose vial or single-dose ampoules.6

It can be given as one drop, up to four times a day in the affected eye or eyes.6
