Trial outcomes

Primary outcomes

1

Ocular Surface Disease Index (OSDI)

A subjective parameter that quantifies corneal discomfort

Time frame
12 weeks
2

Tear Break-up Time (TBUT)

An objective parameter that quantifies stability of tear film

Time frame
12 weeks

Secondary outcomes

1

Schirmer test (basal tear production)

An objective test that assesses basal tear production alone using topical anesthetic drops, by removing the stimulus that triggers reflex tearing.

Time frame
12 weeks
2

Efron scale for bulbar redness

A clinical tool consisting of five photographic, color-calibrated images (graded 0 to 4) that allow practitioners to classify the severity of conjunctival hyperaemia, ranging from normal to severe Grade 0: Normal, pale eyelid margin, minimal conjunctival vessels. Grade 1: Trace/Very Slight redness. Grade 2: Slight/Mild redness. Grade 3: Moderate redness. Grade 4: Severe redness.

Time frame
