Visit 1 (Screening Visit) * Be willing and able to comply with all treatment and follow-up/study procedures. * Be a candidate for routine, uncomplicated cataract surgery. Visit 3 (Postoperative Day 1) * Have undergone routine, uncomplicated cataract surgery (phaco-emulsification with posterior chamber intraocular lens (IOL) implantation, not combined with any other surgery) in the study eye. * Have ≥ Grade 2 anterior chamber (AC) cells (6-15 cells) in the study eye.
Exclusion criteria
* Have a severe/serious ocular condition or history/presence of chronic generalized systemic disease that the Investigator feels might increase the risk to the subject or confound the result(s) of the study. * Have known hypersensitivity or contraindication to the study drug(s) or their components.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With Complete Resolution of Anterior Chamber (AC) Cells | 8 days | White blood cell accumulation in anterior aqueous humor was assessed by the Investigator during slit lamp examination and graded on a 5-point scale: Grade 0 = no cells seen; Grade 1 = 1 to 5 cells; Grade 2 = 6 to 15 cells; Grade 3 = 16 to 30 cells; Grade 4 = \> 30 cells. Lower score indicated better outcome. Complete resolution of AC cells was defined as cell score = 0 in the study eye. |
| Percentage of Participants With Grade 0 Pain in the Study Eye. | 8 days | Ocular pain, defined as a positive sensation of the eye, including foreign body sensation, stabbing, throbbing, or aching, was assessed and graded by subjects on the 6-point scale, with 0=None and 5=Severe. |

| Percentage of Participants With Complete Resolution of Anterior Chamber (AC) Flare in the Study Eye by Visit. | 18 days | Flare was evaluated by the Investigator by assessing the scattering of a slit lamp light beam directed into the anterior chamber (Tyndall effect). Flare was graded on the 5-point scale, with 0=None (best) and 4=Very Severe (worst). Complete resolution of AC flare was defined as Grade 0. |
