- Brief Summary
The primary objective of this study was to compare the safety and efficacy of Durezol™ compared to Pred Forte™ for the treatment of inflammation following cataract surgery in a pediatric population 0 to 3 years of age.
- 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.

- Primary Outcome Measures
Name Time Method Percentage of Patients With an Anterior Cell Grade of 0 (no Cells) at Day 15 ± 2 Days 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.
