INFLAMMATION, DRY EYE DISEASE
Dry Eye Disease (DED) is defined as a multifactorial disease of the ocular surface characterized by a loss of homeostasis of the tear film, accompanied by ocular symptoms, in which tear film instability and hyperosmolarity, ocular surface inflammation and damage as well as neurosensory abnormalities play etiological roles [The healthy tear film provides a smooth refractive surface which is of vital importance for optimal visual acuity [A large number of lipid containing lubricants is now available. These can be prepared as emulsions [
