To characterize clinical outcomes following Kahook Dual Blade ® (KDB)-assisted goniosynechialysis and excisional goniotomy combined with phacoemulsification in eyes with angle-closure glaucoma and cataract.
In this retrospective analysis of existing health records, data were collected from 42 eyes of 24 subjects from preoperative, operative, and postoperative encounters through 12 months of follow-up. 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.
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.
