Brief summary: The primary objectives of this investigation are to show that the performance of CBL-101 Eye Drops is non-inferior to that of Vismed® Multi eye drops in subjects with moderate to severe keratoconjunctivitis sicca after 28 days, and to assess the safety of CBL-101 Eye Drops during a 90-day period with treatment administered 3 to 6 times per day.

Detailed description: Participants in this multicenter, randomized study had a screening visit, then were randomized on Day 0 with follow-up visits on Day 7 (±1), Day 28 (± 3) and Day 90 (±10).

Eligibility criteria: Inclusion Criteria:

1. Subjects must be of legal age (at least 18) on the date the Informed Consent Form (ICF) is signed and with the capacity to provide voluntary informed consent
2. Subjects must be able to read, understand, and provide written informed consent on the Ethics Committee (EC) approved ICF
3. Subjects who are able and willing to comply with all treatment and follow-up, study procedures
4. Subjects who have been using tear substitutes for at least 3 months prior to inclusion, and who will use multidose preservative-free artificial tear (Aqualarm U.P. povidone 2% eye drops in 10 mL bottles) up to 6 times a day for at least 2 weeks immediately prior to randomization
5. Subjects with a score ≥ 1 for at least 2 out of the 7 following symptoms (rated 0 to 4): sensation of dryness, foreign body, burning, stinging, itching, blurred vision, sensitivity to light
6. Subjects with at least 1 eye with the following signs of keratoconjunctivitis sicca :

   * Tear break-up time of ≤ 10sec (mean of 3 measurements) at both screening visit and inclusion visit
   * Total ocular surface staining score ≥ 4 and ≤ 9 at both screening visit and inclusion visit. This assessment combines corneal, nasal and temporal bulbar conjunctival fluorescein staining, each graded 0-5 according to the Oxford Scheme
7. Subjects who have a decimal visual acuity (VA) with habitual correction equal to or better than 0.1 (Monoyer chart) in both eyes
8. Subjects with no systemic treatment or who are receiving stable systemic treatment (unchanged for 1 month or longer)

11. Subjects expected to receive ocular therapy during the study
12. Subjects treated with topical ocular steroidal or non-steroidal antiinflammatory medication within 30 days prior to study start
