Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of adverse device effects | Day 35 | Adverse device effects will be evaluated via ocular examination and ocular symptoms after instillation reported by the subjects |
| Cornea and conjunctiva staining (Oxford scale) (performance) | Day 35 | Main change from baseline of cornea and conjunctiva staining (Oxford scale form 0 to 15, 15 meaning a worse outcome) in the worse eye |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cornea and conjunctiva staining (Oxford scale) | Day 35 | Main change from baseline of cornea and conjunctiva staining (Oxford scale from 0 to 15, 15 meaning a worse outcome) in the contralateral eye |
| OSDI (questionnaire) | Day 35 | Main change from baseline of Ocular Surface Disease Index (OSDI) score |
| Schirmer test | Day 35 | Main change from baseline of Schirmer test result in the worse eye and contralateral eye |
| Tear-Film Break Up Time (TBUT) | Day 35 | Main change from baseline of Tear-Film Break Up Time (TBUT) in the worse eye and contralateral eye |
| Far best corrected visual acuity (FBCVA) | Day 35 | Change from baseline of FBCVA |
| Global performance by the investigator | Day 35 | Global performance assessment by the investigator using a 4-point scale (Unsatisfactory, Not very satisfactory, Satisfactory, Very satisfactory) |
| Global performance by the patient | Day 35 | Global performance assessment by the patient using a 4-point scale (Unsatisfactory, Not very satisfactory, Satisfactory, Very satisfactory) |
| Comfort upon device administration | Day 4, Day 11, Day 18, Day 25, Day 32 | Evaluation of the comfort upon device administration by the patient using a 5-points scale (from very uncomfortable to very comfortable) |
| Patient satisfaction on device performance | Day 0, Day 7, Day 14, Day 21, Day 28, Day 35 | Evaluation of patient satisfaction on 5 Visual Analogical Scales (VAS) from 0 to 100 and calculation of the total score |
| Conjunctival hyperaemia | Day 35 | Main change from baseline of conjunctival hyperaemia using the McMonnies scale (from 0 to 5, 5 meaning a worse outcome) in the worse eye and contralateral eye |
| General safety | Day 35 | Collection and description of ocular and systemic Adverse Events |
