Table 3.

This shows TOF enhancement postsurgery at each postoperative visit at 3, 6 and 12 months compared with baseline TOF

	TOF at baseline	TOF at 3 m (µL/min mm Hg), % of enhancement	Comparison made to baseline	TOF at 6 m (µL/min mm Hg), % of enhancement	Comparison made to baseline	TOF at 12 (µL/min mm Hg), % of enhancement	Comparison made to baseline
Cataract group (n=16)	0.15±0.06	0.20±0.09 (15)	P=0.05, 95% CI −0.11 to 0.1	0.22±0.10 (17)	P=0.02^*, 95% CI −0.12 to −0.01	0.18±0.07 (10)	P=0.25, 95% CI −0.07 to 0.02
POAG group (n=11)	0.13±0.08	0.15±0.06 (14)	P=0.2, 95% CI −0.07 to 0.01	0.17±0.07 (16)	P=0.05^*, 95% CI −0.08 to −0.1	0.17±0.08 (15)	P=0.07, 95% CI −0.09 to 0.006
Overall (n=27)	0.14±0.06	0.18±0.08 (16)	P=0.02^*, 95% CI −0.07 to −0.007	0.20±0.09 (15)	P=0.003^*, 95% CI −0.09 to −0.02	0.17±0.08 (10)	P=0.04^*, 95% CI −0.06 to −0.001

Additionally, the percentage of TOF enhancement is shown.

*Statistically significant.

IOP, intraocular pressure; POAG, primary open angle glaucoma; TOF, tonographic outflow facility.
