Primary Outcome Measures
NameTimeMethod
Peak discomfort score over a 3-minute period after drop instillationUp to Day 3

Ocular discomfort as measured by Visual Analog Scale (VAS) with 0=none to 50=severe, was assessed by subjects every 30 seconds between 0 to 180 seconds after drop instillation (at 0, 30, 60, 90, 120, 150, and 180 seconds). Peak discomfort (maximum observed VAS discomfort score over the 3-minute period) for each subject in each period was analyzed.

Secondary Outcome Measures
NameTimeMethod
Product AcceptabilityUp to Day 3

Product Acceptability assessed by the subject after instillation of drop as a single score where 0=very acceptable and 100=not acceptable.

Ocular SymptomsUp to Day 3

Ocular symptoms (burning, stinging, tearing, blurring, and stickiness) assessed by the subject after instillation of drop as a single score where 0=none to 9=severe.
