6. Schirmer test without anaesthesia ≤ 10 mm/5 minutes in the worst performing eye;
7. Tear film break-up time (TBUT) ≤ 10 seconds in the worst performing eye
8. Best corrected distance visual acuity (BCDVA) score ≥ 0.1 decimal units in both eyes at the time of study enrollment.
9. Only patients who satisfy all Informed Consent requirements may be included in the study. The patient and/or his/her legal representative must read, sign and date the Informed Consent document before any study-related procedures are performed. The Informed Consent form signed by patients and/or legal representative must have been approved by the Ethics Committee for the current study.

2. Patients with a severe Dry Eye condition (severity level 4 according to the Report of the International Dry Eye Workshop -DEWS, 2007)
3. Best corrected distance visual acuity (BCDVA) score of < 0.1 decimal units in either eye at the time of study enrolment
4. Evidence of an active ocular infection in either eye
5. History or presence of ocular surface disorders not related to dry eye in either eye
6. Use of any ocular topical medication other than the study medications for the treatment of ocular diseases including artificial tears during the study period
7. Use of topical cyclosporine, topical corticosteroids or any other topical medication for the treatment of dry eye in either eye within 30 days of study enrolment
8. History of any ocular surgery (including laser or refractive surgical procedures) in either eye within the 90 days before study enrolment. Ocular surgery will not be allowed during the study treatment period and elective ocular surgery procedures should not be planned during the duration of the follow-up period
9. Presence or history of any ocular or systemic disorder or condition that might significantly hinder the efficacy of the study treatment or its evaluation, could possibly interfere with the interpretation of study results, or could be judged by the investigator to be incompatible with the study visit schedule or conduct of trail procedures (e.g. ocular trauma, progressive or degenerative corneal conditions, uveitis, systemic infection.)
10. Known hypersensitivity to one of the components of the study or procedural medications
11. Participation in another clinical study at the same time as the present study or within 90 days of screening/baseline visit
12. History of drug, medication or alcohol abuse or addiction.

    • intend to become pregnant during the study treatment period or,
    • are breast-feeding or,
    • not willing to use highly effective birth control measures, such as: Hormonal contraceptives - oral, implanted, transdermal, or injected and/or mechanical barrier methods - spermicide in conjunction with a barrier such as a condom or diaphragm or an Intra Uterine Device during the entire course of and 30 days after the study treatment periods.
