Two-year Outcomes of Combined Gonioscopy-Assisted Transluminal Trabeculotomy and Cataract Extraction in Ocular
Aim:
To evaluate the 24-month data on efficacy and safety of gonioscopy-assisted transluminal trabeculotomy (GATT), combined with cataract extraction (CE) in patients with ocular hypertension (OHT) and primary open-angle glaucoma (POAG).
Materials And Methods:
A retrospective chart review was conducted of patients undergoing GATT combined with CE from November 2018 to November 2021. The primary outcome was surgical success, defined as a composite endpoint: ≥ 20% intraocular pressure (IOP) reduction AND/OR ≥ 1 medication reduction, without further IOP-lowering procedures, and IOP maintained between 5 and 21 mmHg. Secondary outcomes included: IOP, number of glaucoma medications (NGM), best corrected visual acuity (BCVA), complications, and failure-associated factors.
Results:
A statistically significant reduction in mean IOP (from 18.6 ±3.8 mmHg preoperatively to 15.6 ±3.3 mmHg at 24 months) and NGM (from 2.1 ±1.3 medications to 0.8 ±1.2 medications) was observed (P.
