Time frame: 8 Days
The primary efficacy endpoint is the percentage of participants with ≥ 15 letters of improvement in binocular DCNVA and with < 5 letters of loss in binocular BCDVA from baseline comparing POS-treated participants to placebo-treated participants at 12 hours post-dose at Visit 4 (Day 8).
Time frame: 6 Weeks
This secondary efficacy endpoint is the percentage of participants with ≥ 15 letters of improvement in binocular DCNVA and with < 5 letters of loss in binocular BCDVA from baseline comparing POS-treated participants to placebo-treated participants at 12 hours post-dose at Day 1 (1-hour post-dose), Day 3, and Week 6.
Time frame: 6 Weeks
The percentage of Subjects With ≥ 5, ≥ 10, and ≥ 15 Letters of Improvement in DCNVA From Baseline (Monocular and Binocular) at Day 1 (0.5 hours and 1 hour post-dose), Day 3, Day 8, and Week 6.
Time frame: 6 Weeks
This outcome measure will investigate the percentage of subjects with ≥ 5, ≥ 10, and ≥ 15 letters of improvement in DCNVA from baseline (monocular - study eye) at Day 1 (0.5 hours and 1-hour post-dose), Day 3, Day 8, and Week 6.
Time frame: 6 Weeks
This outcome measure will investigate the change in DCNVA from baseline (binocular) at Day 1 (0.5 hours and 1-hour post-dose), Day 3, Day 8, and Week 6.

1-hour post-dose), Day 3, Day 8, and Week 6.
Time frame: 6 Weeks
This outcome measure will investigate the percentage of subjects with baseline DCNVA ≤ 20/63, ≤ 20/80, ≤ 20/100, ≤ 20/125, and ≤ 20/160 with a ≥ 10-Letter and ≥ 15-Letter Improvement in DCNVA at Day 1 (0.5 hours and 1-hour post-dose), Day 3, Day 8, and Week 6.
Time frame: 6 Weeks
This outcome measure will investigate the percentage of subjects with ≥ 5, ≥ 10, and ≥ 15 letters of improvement in binocular DCIVA from baseline at Day 1 (1-hour post-dose), Day 3, Day 8, and Week 6.
Time frame: 6 Weeks
This outcome measure will investigate the change in binocular DCIVA from baseline at Day 1 (1-hour post-dose), Day 3, Day 8, and Week 6.
Time frame: 6 Weeks
This outcome measure will investigate the percentage of subjects with loss or improvement in BCDVA from baseline (Binocular) at Day 1 (1-hour post-dose), Day 3, Day 8, and Week 6.
Time frame: 6 Weeks

Time frame: 8 Days
This outcome measure will investigate the Percent Change in Pupil Diameter from Baseline at Day 3 & Day 8.
Time frame: 8 Days
This outcome measure will investigate the percentage of subjects with pupil diameter of < 3.5, < 3.0, < 2.5, < 2.0, and < 1.5 mm at Day 3 and Day 8.
Time frame: 8 Days
This outcome measure will investigate the percentage of subjects with pupil diameter of 1.5 to < 2.0 mm, 2.0 to < 2.5 mm, 2.5 to < 3.0 mm, and 3.0 to < 3.5 mm at Day 3 and Day 8.
Time frame: 6 Weeks
