Outcomes

Primary Outcomes

Change in Ocular Surface Disease Index (OSDI)

OSDI is a questionnaire designed to measure eye surface irritation with Rasch analysis to produce estimates on a linear interval scale. The OSDI score ranges from 0 to 100, with higher scores indicating greater severity of symptoms. A score of 0 represents no symptoms, while 100 represents the most severe symptoms.

Time frame: Basal Visit (BV) (day 0) and Final Visit (FV) (day 31+1,).

Incidence of Adverse Events (AE)

Presence/absence adverse events, defined as the appearance of any unfavorable reaction in a patient participating in a clinical investigation in which any pharmaceutical product is being administered, regardless of the causal attribution and whether it was considered related or not to the investigation products.

Time frame: Up to Day 33 (+ 1) (safety call).

Secondary Outcomes

Change in Tear Break-up Time (BUT)

After application of fluorescein stain, using a slit lamp and its cobalt blue filter, the time elapsed after instructing the patient to blink 1 or 2 times and the appearance of dry spots on the ocular surface will be counted and reported as BUT. Normally, this parameter is ≥ 10 seconds.
