12-Month Outcomes of Goniotomy Performed Using the Kahook Dual Blade Combined with Cataract Surgery in Eyes with Medically Treated Glaucoma
Abstract
INTRODUCTION: To describe the 12-month efficacy and safety of goniotomy performed using the Kahook Dual Blade (KDB) in combination with cataract surgery in eyes with medically treated open-angle glaucoma (OAG).
METHODS: This was a prospective, interventional case series conducted at seven centers in North America. Consecutive patients with medically treated OAG and visually significant cataract underwent phacoemulsification combined with goniotomy (PE + goniotomy) using KDB. Indications for glaucoma surgery included reduction of intraocular pressure (IOP) and reduction of IOP-lowering medications. De-identified data were collected and included pre-, intra-, and postoperative data on IOP, the use of IOP-lowering medications, and adverse events through 12 months of follow-up.
RESULTS: Among 52 eyes undergoing surgery, mean IOP was reduced from 16.8 ± 0.6 mmHg at baseline to 12.4 ± 0.3 mmHg at month 12 (P 10 mmHg (n = 2, 3.8%).
CONCLUSION: PE + goniotomy using the KDB significantly lowers both IOP and dependence on IOP-lowering medications in eyes with OAG. Adverse events were not sight-threatening and typically resolved spontaneously.

How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
