We agree with Dr. Lam that 0.051% and 0.015% should be 0.050% and 0.016%, respectively. In addition, the 2-tailed Fisher exact test may be more appropriate. We now have data from another 2 institutions (Table 1). The OR of developing endophthalmitis in the control group to that of the treatment group is 3.584 (interval 0.860 to 20.977). It still fails to show a statistically significant difference between the control and the treatment group (P = .064, 2-tailed Fisher exact test).
