Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Nepafenac 0.3%; Nepafenac Ophthalmic Suspension, 0.3%, one drop in affected eye once daily, for 16 days, beginning one day prior to surgery, continuing on the day of surgery, and for 14 days following surgery. An additional drop was administered between 30-120 minutes prior to surgery.	Drug: Nepafenac Ophthalmic Suspension, 0.3%; Nepafenac Ophthalmic Suspension, 0.3%, one drop in affected eye once daily, for 16 days. An additional drop was administered between 30-120 minutes prior to surgery.
Active Comparator: Nepafenac 0.1%; Nepafenac Ophthalmic Suspension, 0.1%, one drop in affected eye once daily, for 16 days, beginning one day prior to surgery, continuing on the day of surgery, and for 14 days following surgery. An additional drop was administered between 30-120 minutes prior to surgery.	Drug: Nepafenac Ophthalmic Suspension, 0.1%; Nepafenac Ophthalmic Suspension, 0.1%, one drop in affected eye once daily, for 16 days. An additional drop was administered between 30-120 minutes prior to surgery.; Other Names: NEVANAC®
Placebo Comparator: Nepafenac Vehicle 0.3%; Nepafenac Vehicle 0.3%, one drop in affected eye once daily, for 16 days, beginning one day prior to surgery, continuing on the day of surgery, and for 14 days following surgery. An additional drop was administered between 30-120 minutes prior to surgery.	Other: Nepafenac Vehicle 0.3%; Nepafenac Vehicle 0.3%, one drop in affected eye once daily, for 16 days. An additional drop was administered between 30-120 minutes prior to surgery.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Patients Cured at Day 14, Nepafenac 0.3% vs. Nepafenac Vehicle 0.3%	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.	Day 14 postoperative

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Patients Cured at Day 7, Nepafenac 0.3% vs. Nepafenac 0.1%	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.	Day 7 postoperative

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cumulative Percentage of Patients Cured by Visit	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. To be included in the cumulative summary at a visit, a patient must have been declared cured at the visit and remained cured at all subsequent visits.	Day 1, Day 3, Day 7, Day 14
Cumulative Percentage of Patients Pain Free by Visit	Ocular pain was assessed by the patient on a 6-unit scale from 0 (none; absence of positive sensation), to 5 (severe; intense ocular, periocular or radiating pain requiring prescription analgesic). Pain free was defined as an ocular pain assessment score of 0. To be included in the cumulative summary at a visit, a patient must have been declared pain free at the visit and remained pain free at all subsequent visits.	Day 1, Day 3, Day 7, Day 14
