This study is being conducted to show that indomethacin is at least as effective as ketorolac for the prevention of ocular inflammation following cataract surgery.

Inclusion Criteria:

• Subjects must be planning to undergo cataract surgery on one eye by phacoemulsification with posterior chamber intraocular lens, using topical or general anaesthesia.
• Subjects must have a preoperative flare ≤ 15 ph/ms, measured with a laser flare meter(LFM) without pharmacological pupil dilation, within the 2 months preoperatively.

Exclusion Criteria:

• Subjects who have any progressive pathology requiring the use of topical or systemic anti-inflammatory or anti-infectious agents.
• Subjects who take acetylsalicylic acid at doses > 100 mg daily and cannot discontinue usage during the study.
• Subjects who have a history of asthma linked to acetylsalicylic acid or other nonsteroidal anti-inflammatory (NSAI) drug administration.
• Subjects with immunodepression.
• Subjects with a history of intolerance to the study drug or to any NSAI drug.
• Subjects who are monocular for any reason other than cataract.
• Subjects who are treated with local or systemic anti-inflammatory drugs within 10 days prior to inclusion.
