Effect of different incision sites of phacoemulsification on trabeculectomy bleb function: prospective case-control study

Table 3 comparison between the temporal and superior groups regarding the mean intraocular pressure preoperatively and at each follow-up visit

Characteristics	Temporal phaco N = 50	Superior phaco N = 50	P value
Preoperative	17.40 ± 1.64	16.95 ± 1.73	0.40
Postoperative During the first week	17.80 ± 1.58	17.50 ± 1.40	0.53
Postoperative (1 month)	17.45 ± 1.43	17.35 ± 1.66	0.84
Postoperative (3 month)	17.40 ± 1.39	16.90 ± 1.62	0.30
Postoperative (6 month)	17.50 ± 1.36	16.85 ± 1.63	0.18
Postoperative (1 year)	17.55 ± 1.47	16.90 ± 1.71	0.21
P1 (Post op. (1 week) compared to pre op.)	0.03	0.01
P2 (Post op. (1 month) compared to pre op.)	0.77	0.09
P3 (Post op. (3 month) compared to pre op.)	1.00	0.84
P4 (Post op. (6 month) compared to pre op.)	0.63	0.71
P5 (Post op. 1 year) compared to pre op.)	0.51	0.85

Throughout the follow up period the difference in preoperative intraocular pressure and postoperative pressure was insignificant and the intraocular pressure regarding both groups was also insignifica
