8. Have presence of any intraocular, corneal, or conjunctival ocular inflammation (eg, uveitis, iritis, ulcerative keratitis, chronic blepharoconjunctivitis), other than adenoviral conjunctivitis.

9. Have presence of corneal subepithelial infiltrates at Visit 1

10. Have at enrollment or within ≤30 days of Visit 1, a clinical presentation more consistent with the diagnosis of ocular allergy, toxic conjunctivitis, or non-adenoviral ocular infection (eg, bacterial, fungal, acanthamoebae, other or parasitic).

11. Age under 15.

12. Prisoner.

13. Presence of nasolacrimal duct obstruction at Visit 1 (Day 1).

15. Have a history of recurrent corneal erosion syndrome, either idiopathic or secondary to previous corneal trauma or dry eye syndrome; presence of corneal epithelial defect or any significant corneal opacity at Visit 1.

16. Presence of significant, active condition in the posterior segment which requires invasive treatment (eg, intravitreal treatment with vascular endothelial growth factor (VEGF) inhibitors or corticosteroids) and may progress during the study participation period.

17. Have used any topical ocular or systemic anti-viral or antibiotics within <= 7 days of enrollment.

18. Have used any topical ocular NSAIDs within <=1 day of enrollment.

19. Have used any topical ophthalmic steroids in the last <=14 days.

20. Have used any systemic corticosteroid agents within <=14 days of Day 1.

Topical dermal steroids are allowed except in the peri-ocular area.

21. Have used non-corticosteroid immunosuppressive agents within <=14 days of Day 1, oral or topical or both.

22. Have used any topical ophthalmic products, including tear substitutes, and over-the-counter preparations such as lid scrubs, within 2 hours of Visit 1 and be unable to discontinue all topical ophthalmic products for the duration of the study. Use of hot or cold compresses is also not permitted during the study.

23. Have any significant ocular disease (eg, Sjogren's syndrome) or any uncontrolled systemic disease or debilitating disease (eg, cardiovascular disease, hypertension, sexually transmitted diseases/infections, diabetes or cystic fibrosis), that may affect the study parameters, per Investigator's discretion.

24. Any known history of immunodeficiency disorder or known active conditions predisposing to immunodeficiency, such as human immunodeficiency virus, hepatitis B or C, evidence of active hepatitis A (antihepatitis A virus immunoglobulin M), or organ or bone marrow transplantation.

25. Within 30 days prior to the first dose of investigational product:

    1. Have used an investigational product or device, or
    2. Have been enrolled in a clinical study (including vaccine studies) that, in the investigator's opinion, may impact this IVIEW-sponsored study.

26. Pregnant women confirmed with dipstick urine pregnancy testing at Screening and at the final visit.
