About This Trial
Dry eye syndrome (DES) is a highly prevalent ocular condition with potential severe consequences for affected patients. DES can be either caused by decreased tear production or increased tear evaporation, both leading to an instable tear film. Despite many efforts, generally accepted methodologies to diagnose, assess the severity and monitor DES are still lacking. Moreover, widely used clinical me…
