Nepafenac 0.3% Two Study - Full Text View

Purpose

The purpose of this study was to assess the safety and efficacy of Nepafenac Ophthalmic Suspension, 0.3% for the prevention and treatment of inflammation (swelling and redness) and pain in the eye after cataract extraction.

Primary Outcome Measures:

Percentage of Patients Cured at Day 14, Nepafenac 0.3% vs. Nepafenac Vehicle 0.3% [ Time Frame: Day 14 postoperative ] [ Designated as safety issue: No ]
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.

Secondary Outcome Measures:

Percentage of Patients Cured at Day 7, Nepafenac 0.3% vs. Nepafenac 0.1% [ Time Frame: Day 7 postoperative ] [ Designated as safety issue: No ]
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.

Other Outcome Measures:

Cumulative Percentage of Patients Cured by Visit [ Time Frame: Day 1, Day 3, Day 7, Day 14 ] [ Designated as safety issue: No ]
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.
Cumulative Percentage of Patients Pain Free by Visit [ Time Frame: Day 1, Day 3, Day 7, Day 14 ] [ Designated as safety issue: No ]
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.
