Dry eye syndrome is a clinical condition wherein the patient experiences ocular and conjunctival irritation due to decreased tear production and/or excessive tear evaporation.
It is associated with increased osmolarity of the tear film and inflammation of the ocular surface.

Goals of treatment are to relieve symptoms of patients, to improve visual acuity and quality of life of patients, to restore ocular surface and tear film to normal homeostatic state and to correct the underlying defect.
