  16. Tolerability of Study Medication at Visit 2B

    Time frame: upon instillation, 1 minute and 2 minutes post instillation

    Subjects were asked to rate the comfort of the drop in each eye upon instillation, at 1 minute, and at 2 minutes after instillation of study medication. The assessment used a 10-point scale with 0 as very comfortable and 10 as very uncomfortable. Higher scores represent a worse outcome.

  17. Tolerability of Study Medication at Visit 3

    Time frame: upon instillation, 1 minute and 2 minutes post instillation

    Subjects were asked to rate the comfort of the drop in each eye upon instillation, at 1 minute, and at 2 minutes after instillation of study medication. The assessment used a 10-point scale with 0 as very comfortable and 10 as very uncomfortable. Higher scores represent a worse outcome.
