Abstract
Cationorm® is a unique preservative-free option for the treatment of the symptoms of dry eye that offers some advantages over conventional artificial tears. The electrostatic interaction between the positively charged Cationorm® emulsion and the negatively charged cells on the ocular surface prolongs the residence time on the ocular surface. Moreover, as an oily emulsion, Cationorm® augments all three layers of tear film (i.e. lipid layer, aqueous coating and mucin layer), thereby stabilizing the tear film and providing beneficial moisturizing and lubricating effects. Overall, the efficacy and tolerability/safety profiles of Cationorm® in treating mild to severe dry eye disease in clinical trials are similar to, or better than, those of other artificial tears.
