Inclusion criteria

  • Patients 18 years and older
  • Patients willing to take an electronic survey about their tolerability of either study medication.
  • Patients with a recent exacerbation of dry eye characterized by ocular surface discomfort.

Exclusion criteria

Exclusion Criteria:

  • Active, systemic or local disease condition other than DES that causes clinically significant ocular surface irritation that could interfere with the evaluation and treatment of dry eye.
  • Any of the following ocular (eye or eyelid) conditions in either eye within 1 Months prior to the enrollment visit:

    • Ocular surgery (e.g., intraocular, oculoplastic, corneal or refractive surgery procedure)
    • Clinically significant ocular trauma.
    • Active ocular Herpes simplex or Herpes zoster (eye or eyelid) infection.
    • Ocular inflammation (uveitis, iritis, scleritis, episcleritis, keratitis, conjunctivitis)
    • Ocular infection (e.g., viral, bacterial, mycobacterial, protozoan or fungal infection of the cornea, conjunctiva, lacrimal gland, lacrimal sac or eyelids including hordeolum/stye)
  • Moderate to severe (Grade 2-4) allergic, vernal or giant papillary conjunctivitis
  • Eyelid abnormalities that significantly affect lid function (e.g., entropion, ectropion, tumor, edema, blepharospasm, lagophthalmos, severe trichiasis, severe ptosis)
  • Ocular surface abnormality that may compromise corneal integrity (e.g., prior chemical burn, recurrent corneal erosion, corneal epithelial defect, Grade 3 corneal fluorescein staining, or map dot fingerprint dystrophy)
  • Participation in another ophthalmic clinical trial involving a therapeutic drug or device within 30 days prior to the distribution of the survey
  • Participation in this trial in the same patient's fellow eye.
  • Patients who are pregnant or breastfeeding or who may become pregnant during participation in the study.

    The difference in SPEED questionnaire scores before and 4 weeks after treatment.

    Time frame: 4 Weeks

  2. The difference in conjunctival hyperemia

    Slit exam to determine ocular hyperemia using the Schulze Scale before and 4 weeks after treatment

    Time frame: 4 weeks
