Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Ocular dryness is measured in terms of Tear film Break-Up Time (TBUT) in seconds at all four visits (baseline, and approximately 7 days, 5 weeks, 14 weeks) | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Cornea and conjunctiva staining score (Oxford score) measuring using lissamine green staining at all four visits. 2. Meibomian gland expression measured using a rating score from 1-3 at all four visits 3. Subjective expression of dryness measured using an OSDI questionnaire at all four visits. 4. Global performance of the study product measured by the investigator and participant on a four point scale from unsatisfactory to very satisfactory at the third and fourth visits. | — |
