  3. Current use of any topical ophthalmic therapy for dry eye.

  4. Tear break-up time of < 5 seconds or corneal fluorescein staining.

Primary Outcome Measures
NameTimeMethod
Percent of Subjects With ≥ 15 Letters of Improvement in Photopic Binocular DCNVAVisit 2 at 1 hour

The primary efficacy endpoint was the percent of subjects with ≥ 15 letters of improvement in photopic binocular DCNVA on Visit 2 at 1 hour with POS + LDP compared to placebo alone. The improvement in binocular DCNVA for each subject was relative to the subject's own baseline value (Visit 1).

Secondary Outcome Measures
NameTimeMethod
Percentage of Subjects With Improvement of ≥ 5, ≥ 10, and ≥ 15 Letters in DCNVA (Photopic) From BaselineVisit 2 at 0.5 hours, at 2 hours, at 3 hours, at 4 hours, and at 6 hours

The percentage of subjects with improvement of ≥ 5, ≥ 10, and ≥ 15 letters in DCNVA (photopic) from Baseline at 0.5 hours, at 2 hours, at 3 hours, at 4 hours, and at 6 hours

Percentage of Subjects With Improvement of ≥ 15 Letters in DCNVA (Photopic) at 1 Hour and With < 5 Letters of Loss in Photopic Binocular BCDVA From BaselineVisit 2 at 1 hour

The percentage of subjects with improvement of ≥ 15 letters in DCNVA (photopic) at 1 hour and with \< 5 letters of loss in photopic binocular BCDVA from Baseline

Percentage of Subjects With Improvement in DCIVA (Photopic) From BaselineVisit 2 at 1 hour, at 3 hours, and at 6 hours

The percentage of subjects with improvement in DCIVA (photopic) from Baseline of ≥ 5, ≥ 10, and ≥ 15 letters
