Patients who have neither symptoms nor signs do not have dry eye, while asymptomatic patients with signs may develop symptoms after ocular procedures or on certain systemic therapies.

It is accompa- nied by increased osmolarity of the tear film and inflammation of the ocular surface." The updated definition of dry eye from TFOS DEWS II "Dry eye is a multifactorial disease of the ocular surface characterized by loss of homeostasis of the tear film, and accompanied by ocular symptoms, in which tear film instability and hyperosmolarity, ocular surface inflammation and damage, and neurosensory abnormalities play etiological roles." 2 (Osaka, Japan) and Tear Solutions (Charlottesville, Virginia).
