Ocular signs and symptoms were collected for study eyes at each study visit using a 0-4 grading scale, assessed as 0 = none, 1 = minimal/trace, 2 = mild, 3 = moderate, and 4 = severe. The signs and symptoms composite score was the sum of each individual sign or symptom score. Per protocol population (PP).

Outcome results

Primary

Signs and Symptoms Composite Score - Change From Baseline to Day 15 - PP Population

The change from baseline (CFB) to Day 15 (Visit 4) in the ocular signs and symptoms composite score. Ocular signs and symptoms were collected for study eyes at each study visit using a 0-4 grading scale, assessed as 0 = none, 1 = minimal/trace, 2 = mild, 3 = moderate, and 4 = severe. The signs and symptoms composite score was the sum of each individual sign or symptom score. Per protocol population (PP).

Time frame: Baseline, Day 15

Population: The PP population was the population used for the primary efficacy analysis.
