- Schirmer's Test [ Time Frame: 28 Days ]Percentage of subjects who achieve ≥10 mm improvement in Schirmer's Test Score from baseline to day 28
- Mean change from Baseline in Eye Dryness Score (EDS) in the study eye at 5 minutes in the CAE® [ Time Frame: 28 Days ]Eye dryness score is assessed on a visual analogue scale with scores ranging from 0 to 100 (0=no discomfort; 100=maximal discomfort) and lower scores indicate a better outcome.
- Mean change from Baseline in Eye Dryness Score (EDS) in the study eye at Week 4 [ Time Frame: 28 Days ]Eye dryness score is assessed on a visual analogue scale with scores ranging from 0 to 100 (0=no discomfort; 100=maximal discomfort) and lower scores indicate a better outcome.

- Mean change from Baseline in Inferior Corneal Fluorescein Staining in the study eye at Week 4 [ Time Frame: 28 Days ]Mean change from Baseline in Inferior Corneal Fluorescein Staining in the study eye
- Mean change from Baseline in Eye Dryness Score (EDS) in the study eye at Week 2 [ Time Frame: 14 Days ]Eye dryness score is assessed on a visual analogue scale with scores ranging from 0 to 100 (0=no discomfort; 100=maximal discomfort) and lower scores indicate a better outcome.
- Mean change from Baseline in Eye Dryness Score (EDS) in the study eye at Week 1 [ Time Frame: 7 Days ]Eye dryness score is assessed on a visual analogue scale with scores ranging from 0 to 100 (0=no discomfort; 100=maximal discomfort) and lower scores indicate a better outcome.
- Mean change from Baseline in Nasal Corneal Fluorescein Staining in the study eye at Week 4 [ Time Frame: 28 Days ]Mean change from Baseline in Nasal Corneal Fluorescein Staining in the study eye

Ages Eligible for Study: | 22 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Have used and/or desired to use an artificial tear substitute for dry eye symptoms within 6 months prior to Visit 1
Exclusion Criteria:
- Have had any intraocular surgery (such as cataract surgery), extraocular surgery (such as blepharoplasty) in either eye within three months or refractive surgery (e.g. laser-assisted in-situ keratomileusis, laser epithelial keratomileusis, photorefractive keratectomy or corneal implant) within twelve months of Visit 1
- Have a history or presence of any ocular disorder or condition in either eye that would, in the opinion of the Investigator, likely interfere with the interpretation of the study results or participant safety such as significant corneal or conjunctival scarring; pterygium or nodular pinguecula; current ocular infection, conjunctivitis, or inflammation not associated with dry eye; anterior (epithelial) basement membrane corneal dystrophy or other clinically significant corneal dystrophy or degeneration; ocular herpetic infection; evidence of keratoconus; etc. Blepharitis not requiring treatment and mild meibomian gland disease that are typically associated with DED are allowed.
- Have a systemic condition or disease not stabilized or judged by the Investigator to be incompatible with participation in the study or with the lengthier assessments required by the study (e.g., current systemic infection, uncontrolled autoimmune disease, uncontrolled immunodeficiency disease, history of myocardial infarction or heart disease, etc.)
- Have a known hypersensitivity to any of the procedural agents or study drug components
- Have any condition or history that, in the opinion of the investigator, may interfere with study compliance, outcome measures, safety parameters, and/or the general medical condition of the subject
