Outcomes
Primary Outcome Measures
Conjunctival Inflammation at 1 Hour (+30 Minutes) Post CAC on Day 1
Conjunctival Inflammation was assessed by a trained technician post-conjunctival allergen challenge (CAC) on a 0 to 4 scale (0 = best [least inflammation] and 4 = worst [most inflammation]).
The Conjunctival Inflammation was averaged across all Lastacaft-treated eyes to create the average Lastacaft eye Conjunctival Inflammation score, and the Conjunctival Inflammation score was averaged across all Tears Naturale-treated eyes to create the average Tears Naturale eye Conjunctival Inflammation score.
Conjunctival Inflammation 1 Hour (+30 Minutes) Post CAC on Day 2
Conjunctival Inflammation was assessed by a trained technician post-conjunctival allergen challenge (CAC) on a 0 to 4 scale (0 = best [least inflammation] and 4 = worst [most inflammation]).
The Conjunctival Inflammation was averaged across all Lastacaft-treated eyes to create the average Lastacaft eye Conjunctival Inflammation score, and the Conjunctival Inflammation score was averaged across all Tears Naturale-treated eyes to create the average Tears Naturale eye Conjunctival Inflammation score.
Secondary Outcome Measures
Ocular Itching on Day 1 (15 Minutes Post-study Medication Instillation)
CAC was performed 15 minutes after study medication instillation. Ocular Itching was assessed by the patient on a 0-4 scale (0 = best [no itching] to 4 = worst [severe itching]). The ocular itching score was averaged across all Lastacaft-treated eyes to create the average Lastacaft eye ocular itching score, and the ocular itching score was averaged across all Tears Naturale-treated eyes to create the average Tears Naturale eye ocular itching score.
Ocular Itching on Day 2 (15 Minutes Post-study Medication Instillation)
CAC was performed 15 minutes after study medication instillation. Ocular Itching was assessed by the patient on a 0-4 scale (0 = best [no itching] to 4 = worst [severe itching]). The ocular itching score was averaged across all Lastacaft-treated eyes to create the average Lastacaft eye ocular itching score, and the ocular itching score was averaged across all Tears Naturale-treated eyes to create the average Tears Naturale eye ocular itching score.
