Arm && Interventions

Group	Intervention	Description
Nepafenac	Nepafenac Ophthalmic Suspension, 0.1%	Nepafenac Ophthalmic Suspension, 0.1%, 1 drop to the operative eye, 3 times a day, beginning 1 day preoperatively and continuing through the day of surgery and for 14 days postoperatively. An additional dose was administered prior to surgery.
Placebo	Nepafenac Vehicle Ophthalmic Solution	Nepafenac Vehicle, 1 drop to the operative eye, 3 times a day, beginning 1 day preoperatively and continuing through the day of surgery and for 14 days postoperatively. An additional dose was administered prior to surgery.

Primary Outcome Measures

Name	Time	Method
Proportion of Subjects With Clinical Cure at Day 14	Day 14 postoperative	Ocular inflammation was assessed by the Investigator during slit lamp examination. Aqueous cells were scored on a 5-unit scale from 0 (none) to 4 (\>30 cells), and aqueous flare (protein escaping from dilated vessels) was scored on a 4-unit scale from 0 (no visible flare when compared with the normal eye) to 3 (severe - very dense flare). To be considered cured, the patient must have had a score of 0 for both aqueous cells and aqueous flare. The proportion of subjects with a clinical cure is reported as percentage.

Secondary Outcome Measures

Name	Time	Method
Proportion of Subjects Who Were Pain-Free at All Postoperative Visits	Up to Day 14	Ocular pain is defined as a positive sensation of the eye, including foreign body sensation, stabbing, throbbing, or aching. The Investigator scored ocular pain based on the description of pain by the subject. Pain was scored on a 6-unit scale ranging from 0 (none, absence of positive sensation) to 5 (severe, subject reports intense ocular, periocular or radiating pain requiring prescription analgesic). To be considered pain-free at all post operative visits, the patient must have had a score of 0 at Days 1, 3, 7, and 14 and any unscheduled visit. The proportion of subjects who were pain-free at all post-operative visits is reported as percentage.
