Comparison of Odds Ratios for Risk of Postoperative Endophthalmitis between the Immediate Sequential Bilateral Cataract Surgery and Delayed Sequential Bilateral Cataract Surgery or Unilateral Surgery Groups

Duration of Postoperative Follow-up for Endophthalmitis Diagnosis (wks)	Diagnosis	Eye	Odds Ratio* (95% Confidence Interval) and P Value
2	Endophthalmitis diagnosis	Either eye†	0.81 (0.64–1.01), 0.08
		First eye	0.78 (0.56–1.06), 0.14
	Diagnosis with supporting clinical findings	Either eye†	0.79 (0.61–1.01), 0.07
		First eye	0.74 (0.50–1.04), 0.10
4	Endophthalmitis diagnosis	Either eye†	1.07 (0.88–1.28), 0.49
		First eye	0.91 (0.68–1.18), 0.48
	Diagnosis with supporting clinical findings	Either eye†	1.08 (0.87–1.31), 0.47
		First eye	0.88 (0.64–1.17), 0.40
6	Endophthalmitis diagnosis	Either eye†	1.11 (0.93–1.32), 0.34
		First eye	0.88 (0.67–1.13), 0.25
	Diagnosis with supporting clinical findings	Either eye†	1.11 (0.91–1.33), 0.31
		First eye	0.84 (0.62–1.12), 0.25

^*For endophthalmitis developing after immediately sequential bilateral cataract surgery relative to delayed sequential bilateral cataract surgery or unilateral surgery based on logistic regression model adjusted for decade of life, sex, race, insurance, and history of age-related macular degeneration, diabetic retinopathy, and glaucoma.

^†Patients demonstrated postoperative endophthalmitis in either the first or second surgery eye, or both.
