This is a phase 2, multicenter, double-masked, randomized, vehicle-controlled, parallel-comparison study conducted at sites in the US assessing the safety and ocular efficacy of VVN461 for treating post-operative ocular inflammation in subjects who undergo routine unilateral CELR surgery via phacoemulsification without surgical complication. Approximately 90 subjects (30 per group) will be randomized in a 1:1:1 ratio. Subjects will administer 1 eye drop in the study eye four times a day (QID) for 14 days.
