  • Patients (minimum age 18) with dry eye. Criteria for the diagnosis must include the following two criteria at Visit 1 (Day 0).

    1. Patients' response to the self-assessment of dry eye status is at least "Some of the time" to the question, "How often have your eyes felt dry enough to want to use eye drops?".
    2. Sodium fluorescein (NaFL) corneal staining sum score of >4 in either (worse) eye using a 0-15 point grading system.
  • Able and willing to follow study instructions.
  • Patients must have best corrected visual acuity of 0.6 logMAR or better in each eye as assessed using an ETDRS chart at Visit 1.

Exclusion Criteria:

  • Diagnosis of Sjogren's syndrome (or suspected to have Sjogren's syndrome).
  • History or evidence of ocular or intraocular surgery in either eye within the last one year.
  • History or evidence of serious ocular trauma in either eye within the past six months.
  • History or evidence of corneal transplant or transplant variant procedures.
  • History of intolerance or hypersensitivity to any component of the study medications.
  • History of glaucoma or current ocular hypertension in either eye, or treatment for either condition within 6 months prior to Visit 1.
  • History or evidence of corneal conditions, other than dry eye, that may affect the corneal structure.
  • Use of any concomitant topical ocular medications including artificial tears during the study period.
  • Females of childbearing potential (those who are not surgically sterilized or postmenopausal) may not participate in the study if any of the following conditions exist:

    1. They are breastfeeding,
    2. They are unwilling to undergo urine pregnancy test at screening and upon exiting the study,
    3. They have a positive urine pregnancy test at screening,
    4. They intend to become pregnant during the study, or
    5. They do not agree to use adequate birth control methods for the duration of the study.
  • Use of RESTASIS(R) 0.05% or an ocular steroid (e.g. Lotemax(R) 0.5%) within 30 days of Visit 1.
  • Use of systemic medications that have not been stable for 30 days prior to Visit 1.
  • Ocular conditions such as active (acute) blepharitis, conjunctival infections, iritis or any other ocular condition that may preclude the safe administration of the test article.
  • Contact lens wear during the study period. Contact lens wear must have been discontinued at least four weeks prior to Visit 1.
  • Use of punctal plugs or punctal cautery.
  • Use of lid scrubs/warm compresses within 14 days of Visit 1.
