1. History of eye trauma/surgery within the last 6 months that resulted in corneal scarring
2. DED secondary to scarring, irradiation, alkali burns, cicatricial pemphigoid, or destruction of conjunctival goblet cells, Stevens-Johnson syndrome, active blepharitis, or lid margin inflammation
3. Abnormal cornea (e.g., keratoconus or corneal epithelial defect, pterygium, or history of herpetic keratitis)

3. Use of any eye drops (prescription or over the counter) in the study eye within 24 hours prior to Visit 1
4. Use of any oral medications known to cause ocular drying (e.g., antihistamines, antidepressants, etc.) on a non-stable regimen within 1 month prior to Visit 1 or is expected to be unstable during the trial
5. Had a LipiFlow®, intense pulsed light (IPL) therapy, etc. in the study eye within 3 months prior to Visit 1

7. Have worn soft contact lenses within either 3 days prior to the study or rigid gas-permeable contact lenses for 1 month prior to Visit 1 or any planned wear during the study
8. Have undergone intraocular surgery or ocular laser surgery in the study eye within 3 months prior to Visit 1
9. Have ocular allergies that are/expected to be active during the trial period
10. Have active ocular or systemic infection (bacterial, viral, or fungal), including fever
