Presurgical Exclusion Criteria:
- Systemic administration of any corticosteroid in the 2 weeks prior to study enrollment.
- Periocular injection in the study eye of any corticosteroid solution within 4 weeks prior to instillation of the study drug, or of any corticosteroid depot within 2 months prior to instillation of the study drug.
- Instillation of any topical ocular corticosteroid or NSAID within 24 hours prior to instillation of the study drug or during the course of the study, with the exception of presurgical administration of a topical NSAID to prevent miosis.

Intervention / Treatment |
---|---|
Placebo Comparator: Placebo
Placebo for 14 days.
Placebo was administered BID for 14 days and QID for 14 days.
The outcomes of the 2 placebo groups were examined and were determined to be statistically indistinguishable so the placebo groups were pooled for comparison with the difluprednate groups.

Experimental: Difluprednate 0.05% BID
Difluprednate 0.05% 1 drop BID for 14 days.
