Primary Outcome Measures:
  • Anterior Chamber Cell Grade of "0" on Day 8 (Difluprednate QID vs Placebo). [ Time Frame: Day 8 (QID) ]

Enrollment: 219
Arms Assigned Interventions
Experimental: Difluprednate 0.05% BID
Difluprednate 0.05% 1 drop BID for 14 days
Drug: Difluprednate
Experimental: Difluprednate 0.05% QID
Difluprednate 0.05% 1 drop QID for 14 days
Drug: Difluprednate
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.
Drug: Placebo

  • 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.
  • Any history of glaucoma or ocular hypertension in the study eye.

  • Pregnancy or lactation.
  • Participation in any study of an investigational topical or systemic new drug or device within 30 days prior to screening, or at any time during the study.
  • Prior participation in the study described in this protocol.
  • Unable or unwilling to give signed informed consent prior to participation in any study related procedures.

Postsurgical Exclusion Criteria:

  • Ocular hemorrhage which interferes with evaluation of postsurgery inflammation.
  • Injection of gas into the vitreous body during surgery.
