DED secondary to scarring, irradiation, alkali burns, cicatricial pemphigoid, or destruction of conjunctival goblet cells (as with vitamin A deficiency). 5. abnormal lid anatomy that caused incomplete eyelid closure 6. abnormal cornea shape (keratoconus) 7. corneal epithelial defect or significant confluent staining or filaments 8. history of herpetic keratitis. 9. has a pterygium in either eye. 10. ocular or periocular rosacea that in the judgement of the Investigator interfered with the trial 2. Has used any topical ocular steroids treatments, prescription dry eye therapy including varenicline nasal spray, or topical anti-glaucoma medication within 60 days prior to Visit 1. 3. Have had a LipiFlow procedure, intense pulse light procedure or any kind of other procedure affecting meibomian glands within 6 months prior to Visit 2. 4. Have received or removed a permanent punctum plug within 3 months (6 months for dissolvable punctum plugs) prior to Visit 2. 5. Have used any eye drops (prescription or artificial tears) and/or TrueTearTM device (intranasal tear neurostimulator) within 24 hours before Visit 2. 6. Have active ocular allergies or ocular allergies that are expected to be active during the trial period. 7. Have worn contact lenses within 1 month of Visit 1 or anticipate using contact lenses during the trial. 8.

Have taken isotretinoin (e.g. Accutane, Myorisan, Claravis, Amnesteem) within 6 months of Visit 1. 16.

Is currently enrolled in an investigational drug or device study or had used an investigational drug or device within 60 days of Visit 2.
