Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Parents or guardians instilled patients' assigned study medications once on the day of surgery (Day 0) and 4 times daily (QID) beginning on the day after surgery (Day 1) for 14 days followed by a tapering period of 14 days (dependent upon the Investigator's determination of adequate response to treatment). Patients were evaluated for safety and efficacy on the following visits: Day 0 (day of surgery), Day 1, Day 8 ± 1 day, Day 15 ± 2 days and Day 29 ± 2 days (end of study drug treatment). Additional safety visits occurred at 1 week after the last dose + 2 days and at 3 Months + 1 week. No inferential statistical analysis was planned for this study. Data was summarized using descriptive statistics.

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 With an Anterior Cell Grade of 0 (no Cells) at Day 15 ± 2 Days
Time Frame: Day 15 ± 2 days
Anterior cell grade was assessed by the Investigator during slit lamp or ophthalmoscopy/light examination and graded on a 5-point scale: Grade 0=0 cells; Grade 1=1 to 10 cells; Grade 2=11 to 20 cells; Grade 3=21 to 50 cells; Grade 4=>50 cells. The presence of blood cells (red and white) in the anterior chamber of the eye (the fluid-filled space inside the eye between the iris and the cornea's innermost surface) is a sign of intraocular inflammation. A score of 0 indicates an absence of inflammation.
Day 15 ± 2 days

Secondary Outcome Measures
