Purpose: The purpose of this study was to characterize reductions in intraocular pressure (IOP) and the need for IOP-lowering medications following phacoemulsification combined with Kahook Dual Blade-assisted goniosynechialysis and excisional goniotomy in eyes with angle-closure glaucoma and cataract.

Methods: In this retrospective, interventional case series, preoperative, operative, and postoperative data were collected through 6 months of follow-up from 42 eyes of 24 subjects. Outcomes included mean IOP reduction, reduction in IOP-lowering medications, and the proportion of patients achieving IOP reduction ≥20%, IOP≤18 mm Hg, and reduction of ≥1 medication.

Results: Preoperatively, mean (SE) IOP was 25.5 (0.7) mm Hg and the mean number of IOP-lowering medications used was 2.3 (0.1) per eye. Through 6 months of follow-up, mean IOP reductions of 10.1 to 12.8 mm Hg (38.4% to 49.5%; P<0.0001) and mean IOP medication reductions of −2.2 to −2.3 (91.7% to 98.4%; P<0.0001) were seen. At month 6, 92.9% of eyes (39/42) achieved IOP≤18 mm Hg, 100% (42/42) achieved IOP reduction of ≥20%, 100% (42/42) required ≥1 fewer medications for IOP control, and 85.7% (36/42) were medication free.

Conclusions: Phacoemulsification combined with Kahook Dual Blade-assisted goniosynechialysis and excisional goniotomy safely provides statistically and clinically meaningful reductions in both IOP and the need for IOP-lowering medications in eyes with angle-closure glaucoma.
