Outcomes included changes in mean IOP, IOP-lowering medications, and logMAR best-corrected visual acuity (BCVA), as well as the proportions of patients achieving IOP reductions ≥20%, IOP ≤18 mmHg, and a reduction of ≥1 medication.Results: Preoperative, mean (standard error) IOP was 25.5 (0.7) mmHg and at Month 12 was reduced by 12.3 (0.73) mmHg (−47.2%; p<0.0001). The mean number of IOP-lowering medications used was 2.3 (0.1) preoperatively and was reduced at Month 12 by 2.2 (0.12) (−91.7%; p<0.0001). At Month 12, 92.9% of eyes achieved IOP ≤18 mmHg, 100% achieved IOP reduction of ≥20%, 95.2% required ≥1 fewer medications for IOP control, and 85.7% (36/42) were medication-free. Mean LogMAR BCVA improved from 0.547 (0.06) at baseline to 0.159 (0.07) at Month 12.Conclusion: KDB-assisted goniosynechialysis and excisional goniotomy at the time of phacoemulsification safely provide significant reductions in both IOP and IOP-lowering medication burden in eyes with angle-closure glaucoma, while simultaneously improving visual acuity.Keywords: glaucoma, angle closure, synechialysis, goniotomy, MIGS  Dorairaj STam MDBalasubramani GKDove Medical Pressarticleglaucomaangle closuresynechialysisgoniotomyMIGSOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 13, Pp 1779-1785 (2019)
