Early outcomes of 5-0 Prolene gonioscopy-assisted transluminal trabeculotomy combined with phacoemulsification in eyes of Indian glaucoma patients

Abstract

Purpose: To study the early postoperative efficacy and safety of 5-0 Prolene gonioscopy-assisted transluminal trabeculotomy (GATT) combined with phacoemulsification in Indian eyes. Methods: This was a prospective, interventional study. Patients with primary and secondary glaucoma who underwent GATT combined with phacoemulsification (Phaco-GATT) or standalone GATT were included. All patients were evaluated on postoperative days 1, 15, and 30, as well as 3 months and 6 months postoperatively. Baseline and follow-up visits were compared to determine the significant difference in the number of intraocular pressure (IOP), antiglaucoma medications (AGM), and best corrected visual acuity (BCVA). Other outcome measures included surgical success, complications, and interventions. A P value of 6–≤21 mmHg/20% reduction without AGM) was 96.7% in the Phaco-GATT group and 91.2% in the GATT group. BCVA improved from log of minimum angle of resolution 0.30 to 0.00 (P 1 mm) was seen in six patients, out of which two patients required anterior chamber wash. IOP spikes (>30 mmHg) were seen in three patients. Conclusion: In Indian eyes, GATT combined with phacoemulsification and standalone GATT are efficacious and safe with good surgical outcomes.
