Abstract Details

Purpose:

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.

Setting:

2 clinical practices (1 in the United States and 1 in Vietnam)

Methods:

In this retrospective, interventional case series, preoperative, operative, and postoperative data were collected through 12 months of follow-up in 42 eyes of 24 subjects. Outcomes included mean IOP reduction, mean reduction in IOP-lowering medications, the proportion of patients achieving IOP reductions >20%, IOP <18 mmHg, and a reduction of >1 medication, and mean logMAR best-corrected visual acuity (BCVA).

Results:

Preoperatively, mean (standard error) IOP was 25.5 (0.7) mmHg and the mean number of IOP-lowering medications used was 2.3 (0.1) per eye. At Month 12, mean IOP was reduced by 12.3 (0.73) mmHg (47.2%; p<0.0001), and the mean number of medications used was reduced by 2.2 (0.12) medications (91.7%; p<0.0001). At Month 12, 92.9% of eyes (39/42) achieved IOP <18 mmHg, 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. LogMAR BCVA improved from a mean of 0.547 (0.06) at baseline to 0.159 (0.07) at Month 12.

Conclusions:

Phacoemulsification combined with KDB-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.
