Outcomes
Primary Outcomes
Ocular Itching at Duration of Action (24 Hours Post-dose)
Time Frame: 3, 5, 7 minutes post-CAC
A treatment efficacy CAC was performed 24 hours after drop instillation. Ocular itching was assessed by the patient on a 0-4 scale (0=none to 4=severe). Average of ocular itching score over both eyes was analyzed.
Ocular Itching at Onset of Action (15 Minutes Post-dose)
Time Frame: 3, 5, 7 minutes post-CAC
A treatment efficacy CAC was performed 15 minutes after drop instillation. Ocular itching was assessed by the patient on a 0-4 scale (0=none to 4=severe). Average of ocular itching score over both eyes was analyzed.
Conjunctival Redness at Duration of Action (16 Hours Post-dose)
Time Frame: 7, 15, 20 minutes post-CAC
A treatment efficacy CAC was performed 16 hours after drop instillation. Conjunctival Redness was assessed by the patient on a 0-4 scale (0=none to 4=severe). Average of conjunctival redness score over both eyes was analyzed.
Conjunctival Redness at Duration of Action (24 Hours Post-dose)
Time Frame: 7, 15, 20 minutes post-CAC
A treatment efficacy CAC was performed 24 hours after drop instillation. Conjunctival Redness was assessed by the patient on a 0-4 scale (0=none to 4=severe). Average of conjunctival redness score over both eyes was analyzed.
Conjunctival Redness at Onset of Action (15 Minutes Post-dose)
Time Frame: 7, 15, 20 minutes post-CAC
A treatment efficacy CAC was performed 15 minutes after drop instillation. Conjunctival Redness was assessed by the patient on a 0-4 scale (0=none to 4=severe). Average of conjunctival redness score over both eyes was analyzed.
Ocular Itching at Duration of Action (16 Hours Post-dose)
Time Frame: 3, 5, 7 minutes post-CAC
A treatment efficacy CAC was performed 16 hours after drop instillation. Ocular itching was assessed by the patient on a 0-4 scale (0=none to 4=severe). Average of ocular itching score over both eyes was analyzed.
