The purpose of this phase III study is to determine the efficacy of difluprednate in the treatment of inflammation following ocular surgery.

Conditions

Inflammation

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: DOUBLE

Study Groups

Difluprednate 0.05% BID

Difluprednate 0.05% 1 drop BID for 14 days

Group Type: EXPERIMENTAL

Difluprednate

Intervention Type: DRUG

Difluprednate 0.05% QID

Difluprednate 0.05% 1 drop QID for 14 days

Group Type: EXPERIMENTAL

Difluprednate

Intervention Type: DRUG

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.
