Conditions
Brief summary
The objective of this clinical study is to compare the safety and efficacy of mapracorat ophthalmic suspension, 3% with its vehicle for the treatment of postoperative inflammation and pain following cataract surgery. Participants from the United States and Canada will be recruited for this study.

Inclusion criteria
* Subjects who are candidates for routine, uncomplicated cataract surgery. * Subjects who, in the Investigator's opinion, have potential postoperative pinhole Snellen visual acuity (VA) of at least 20/200 in the study eye. * Subjects who have ≥ Grade 2 (6 - 15 cells) AC cells in the study eye following cataract surgery (postoperative day 1).
Exclusion criteria
* Subjects who 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. * Any intraocular inflammation in either eye (cells or flare score greater than Grade 0 at slit lamp examination) or ocular pain greater than Grade 1 in the study eye at the Screening Visit. * Presence of active external ocular disease: infection or inflammation of the study eye. * Subjects who have known hypersensitivity or contraindication to the study drug(s) or their components. * Subjects who currently require or are expected to require treatment with any medication listed as a disallowed medication per the Disallowed Therapy section of the protocol.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With Complete Resolution of Anterior Chamber (AC) Cells | 8 days | Anterior chamber (AC) cells were assessed using a 0 to 4 grading scale by an ophthalmologist using slip lamp biomicroscopy. A slit lamp examination of the lids, conjunctiva, limbus, cornea, anterior chamber, vitreous, and lens was performed without pupil dilation. Accumulation of white blood cells in aqueous was assessed. The grades were defined as: 0 = No cells seen; 1 = 1 - 5 cells; 2 = 6 - 15 cells; 3 = 16 - 30 cells; 4 = \>30 cells. Complete resolution of AC cells was defined as Grade 0. |
| Percentage of Participants With Grade 0 Pain | 8 days | Ocular pain was defined as a positive sensation of the eye, including foreign body sensation, stabbing, throbbing, or aching. The scores ranged from 0=None to 5=Severe, where higher scores indicated worse pain. |
