Comparison of outcomes of 180-degree Tanito Microhook trabeculotomy versus 360-degree gonioscopy-assisted transluminal trabeculotomy combined with phacoemulsification in open-angle glaucoma

To compare the one-year surgical outcomes of Tanito microhook Trabeculotomy combined with phacoemulsification (Phaco-TMH) and 5-0 prolene gonioscopy-assisted transluminal trabeculotomy combined with phacoemulsification (Phaco-GATT) in mild-moderate Open-angle glaucoma Prospective, comparative, non-randomised, interventional study Patients with mild-to-moderate OAG and visually significant cataract Methods:110 patients underwent Phaco-TMH (Group 1, N=55) or Phaco-GATT (Group 2, N=55). The primary outcome measures included changes in intraocular pressure (IOP), antiglaucoma medications (AGM), and best-corrected visual acuity (BCVA). Success was defined as a combination of at least 20%, 25%, or 30% reduction in IOP and an absolute IOP of less than 21, 18, or 15 mm Hg, respectively (Criteria 1, 2, and 3). Additionally, interventions and complications were compared between the groups. In Group 1, mean IOP reduced significantly from 26.55±5.22mmHg to 14.60±3.87 mmHg, and in Group 2 from 25.45± 5.65mmHg to 12.80±3.12 mmHg at 12 months (p
