Dry Eye, Lipid Layer, Liposic, Tear Film, Tears Naturale Forte
Conditions
Brief summary
With the potential to address evaporative dry eye, Liposic and Tears Naturale Forte have been developed in which phospholipid liposomes are delivered to the tear film via the surface of the closed eyelid. This study compare the effects of Liposic and Tears Naturale Forte application on the lipid and stability of the tear film in dry eye patients
