Primary Outcome Measures

Name	Time	Method
Number of Participants With Clinical Resolution Among Who Received SHP640 or Placebo on Day 5	Day 5	Clinical resolution was defined as absence (score=0) of bulbar conjunctival injection and ocular conjunctival discharge in the study eye. Bulbar conjunctival injection was assessed based on 0 (Normal conjunctival vascular pattern) - 4 (Markedly prominent, intense diffuse hyperemia) scale which used pictures from validated bulbar redness (VBR) scale. Ocular conjunctival discharge was assessed based on 0 (No evidence of discharge in conjunctiva) - 3 (Abundant quantity of mucopurulent or purulent discharge) scale. The study eye was defined as an eye with score of at least 1 for both ocular conjunctival discharge and bulbar conjunctival redness at baseline. Data analysis was performed in SHP640 and placebo reporting groups only but not in PVP-I 0.6%.

Number of Participants With Expanded Clinical Resolution	Day 3, 5, 8 and 12	Expanded clinical resolution was defined as a global clinical score of 0, 1, or 2 with neither injection nor discharge having a score of 2. Global clinical score was defined as the sum of bulbar conjunctival injection and ocular conjunctival discharge scores. Bulbar conjunctival injection was assessed based on 0 (Normal conjunctival vascular pattern) - 4 (Markedly prominent, intense diffuse hyperemia) scale which used pictures from VBR scale. Ocular conjunctival discharge was assessed based on 0 (No evidence of discharge in conjunctiva) - 3 (Abundant quantity of mucopurulent or purulent discharge) scale.
Time to Clinical Resolution	Baseline to Day 12	Clinical resolution was defined as absence (score of 0) of bulbar conjunctival injection and ocular conjunctival discharge in the study eye.
