| Assessment | |
| Primary outcomes | IOP was measured using a rebound tonometer at 1 hour preoperatively; at the end of surgery (surgically adjusted to range between 15 and 25 mmHg); and at 2, 4, 6, 8, and 24 hours postoperatively. |
| Key secondary outcomes | 1) Static visual fields sensitivity with 30-2 program of the Humphrey Field Analyzer.
2) Flare intensity at 6 hours after surgery 3) Wound states determined using anterior segment-optical coherence tomography 4) Visual acuity, refraction, corneal astigmatism |

|
| Interventions/Control_1 | 55 eyes of 55 patients who received topical prostaglandin F2A analogue just after surgery (Travoprost 0.004%, Travatanz; Alcon Pharmaceutical; Fort Worth, TX, USA). | |
| Interventions/Control_2 | 55 eyes of 55 patients who received topical B-blocker just after surgery (0.5% Timolol maleate, Timoptol; Santen Pharmaceutical, Tokyo, Japan). | |
| Interventions/Control_3 | 55 eyes of 55 patients who received topical carbonic anhydrase inhibitor (CAI) just after surgery (Brinzolamide 2%, Azopt; Alcon). | |

| Key inclusion criteria | Clinical research coordinators began screening of all consecutive eyes with medically well-controlled POAG or pseudoexfoliation glaucoma with topical antiglaucoma agents (an IOP of 21 mmHg or less at 2 continuous prior visits) that were scheduled for phacoemulsification with implantation of a hydrophobic acrylic intraocular lens (IOL). | |||
| Key exclusion criteria | Exclusion criteria were 1) eyes with any ocular pathology other than cataract and glaucoma; 2) eyes scheduled for planned extracapsular or intracapsular cataract extraction; 3) history of previous ocular surgery or inflammation; 4) patients with contraindication for administration of prostaglandin F2A analogues, B-blockers, topical carbonic anhydrase inhibitor; 5) patient refusal; 6) any anticipated difficulties with examination or follow-up; and 7) patients who were included in another study. | |||
