Table 2 Visual outcomes and IOP reduction at 12 months postoperatively

From: Long-term outcomes of prediction error after combined phacoemulsification and trabeculectomy in glaucoma patients

Variables Combined group (n=60) Phaco-only group (n=60) P value a
Baseline
 BCVA (LogMAR) 0.68 ± 0.82 0.47 ± 0.58 0.124
 IOP (mmHg) 29.60 ± 10.04 14.52 ± 2.50 <  0.001
Postoperative
 BCVA (LogMAR) 0.48 ± 0.86 0.24 ± 0.56 0.065
 IOP (mmHg) 13.35 ± 3.12 13.23 ± 2.20 0.814
P value b
 BCVA 0.001 <  0.001  
 IOP <  0.001 <  0.001  
  1. IOP indicates intraocular pressure, BCVA best-corrected visual acuity, LogMAR logarithm of the minimum angle of resolution
  2. aIndependent t-test for combined group and phaco-only group
  3. bPaired t-test for baseline and postoperative values
