Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Patients Cured at Day 14, Nepafenac 0.3% vs. Nepafenac Vehicle 0.3%
Time Frame: 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.
Day 14 postoperative

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Patients Cured at Day 7, Nepafenac 0.3% vs. Nepafenac 0.1%
Time Frame: Day 7 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.
Day 7 postoperative

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Cumulative Percentage of Patients Cured by Visit
Time Frame: Day 1, Day 3, Day 7, Day 14
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
Time Frame: Day 1, Day 3, Day 7, Day 14
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

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
