Corneal Tear Film Imaging of the Cornea Before and After Restasis Therapy

The TFI is an imaging device based on standard camera that uses white light to image the tear film in an ultra high resolution. DES patients in this study will be imaged before and 3 months after initiation of treatment with Restasis (the treatment indicated for their condition).

Restasis therapy is given to all of the patients as indicated for moderate-severe DES. TFI imaging is performed before and 3 months after initiation of therapy.
