Outcome

Type	Measure	Description	Time frame	Safety issue
Other	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	No
Other	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	No
Primary	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	No
Secondary	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	No
