Design outcomes

Primary

MeasureTime frame
Since this study was a phase II there were no primary or secondary outcomes. Our aim was to analyse the efficacy and safety of SVS20 versus saline and carbomer and to find a parameter that could be used as the primary criterion for the following pivotal phase III study (ISRCTN91412460). Therefore, the following parameters were assessed: 1. Efficacy and tolerability: 1.1. Number of instillations 1.2. Staining with lissamine green 1.3. Symptom intensity and frequency 1.4. Repercussion of symptoms on activities of daily life 1.5. Comfort of the eye drops (presence and duration of blurred vision after instillation) 1.6. Slit lamp examination 1.7. Tear volume (Schirmer I test) 1.8. Tear film BUT 1.9. Corneal staining with fluorescein 1.10. Global evaluation of efficacy 2. Safety: 2.1. Comfort of the eye drops (presence and duration of blurred vision) 2.2. BCVA 2.3. Impairment of dry eye symptoms 2.4. Ocular adnexa examination 2.5. Adverse events reporting Parameters were measured at V1 (Day-16 to Day-12), V2 (Day 0) and V3 (Day 28).
