Notes: Subjects were asked to score their level of discomfort using the Ora Calibra Ocular Discomfort Scale (0–4, where 0 is no discomfort and 4 is constant discomfort) prior to drop instillation and at 5, 20, and 60 minutes after instillation at Visit 1; single measures were collected at Visits 2 and 3.
