Study Endpoints

Primary Endpoints

Proportion of Subjects With No Anterior Chamber Cells (Grade 0) at Day 14
Day 14 post-surgery

The proportion of subjects who achieve grade 0 anterior chamber cells (no detectable inflammatory cells) as assessed by slit-lamp biomicroscopy, indicating complete resolution of postoperative ocular inflammation.

Proportion of Subjects With No Ocular Pain (NPRS = 0) at Day 8
Day 8 post-surgery

The proportion of subjects reporting no ocular pain (score of 0 on the Numeric Pain Rating Scale \[NPRS\]), reflecting complete resolution of postoperative pain following ophthalmic surgery.

Treatment Arms

ArmTypeDescription
TRIESENCE Treatment ArmEXPERIMENTALExperimental Arm (TRIESENCE): Participants receive a single 100 µL subconjunctival injection of TRIESENCE (triamcinolone acetonide injectable suspension) administered at the conclusion of ophthalmic surgery. The injection is given under aseptic conditions to evaluate its effectiveness in reducing postoperative ocular inflammation and pain.
Placebo Comparator: Placebo (Sham) Control ArmPLACEBO_COMPARATORArm Description: Placebo Comparator Arm (Sham): Participants undergo a sham injection procedure at the end of surgery that mimics the active treatment process without administering TRIESENCE. This control is used to maintain masking and allow comparison of efficacy and safety outcomes.
