Development of macular edema after cataract surgery

Macular edemaa	Nepafenac n = 125	Vehicle n = 126	P-valueb
	n (%)	n (%)
Within 30 days	3 (2.4)	11 (8.7)	0.029
Within 60 days	3 (2.4)	19 (15.1)	<0.001
Within 90 days	4 (3.2)	21 (16.7)	<0.001

Notes:

^aMacular edema was defined as ≥30% increase from the presurgical baseline in central subfield macular thickness as measured by optical coherence tomography (Stratus OCT 3);

^bP-value was calculated from a chi-square test.
