          8. Willing to discontinue use of current dry eye therapy (including artificial tears or
             ocular lubricants) during the study as of the run-in period.

          9. Female subjects of childbearing potential must have a negative urine pregnancy test at
             Screening. Women of childbearing potential (ie, women who are not either
             postmenopausal for one year or surgically sterile) must use an acceptable form of
             contraception throughout the study.

        Exclusion Criteria:

             prior to Screening and throughout the study period. These include the following
             medications:

               -  Immunomodulators (permitted if dose is stable for 3 months prior to screening and
                  does not change during the study period)

             months prior to Screening.

         11. Diagnosis of chronic uveitis.

         12. Corneal transplant (e.g., penetrating keratoplasty, lamellar keratoplasty, Descemet's
             stripping endothelial keratoplasty (DSEK) ).

         13. Corneal refractive surgery (e.g., laser-assisted in situ keratomileusis (LASIK]) photo
             refractive keratectomy (PRK), limbal relaxing incision (LRI) ) within 6 months prior
             to screening or postoperative refractive surgery symptoms of dryness that have not
             resolved.

         14. Cataract surgery within 3 months prior to Screening.

         15. Non-laser glaucoma surgery at any time; glaucoma laser procedures within 3 months

             whether congenital or acquired.

             redundant conjunctiva).

             the study.

         26. Has a severe/serious ocular condition, or any other unstable medical condition that,
             in the Investigator's opinion, may preclude study treatment or follow-up.

         28. Participation in any drug or device clinical investigation within 30 days prior to
             entry into this study and/or during the period of study participation.
