30-MONTH OUTCOMES OF KAHOOK DUAL BLADE GONIOTOMY COMBINED WITH CATARACT SURGERY IN EYES WITH MEDICALLY TREATED GLAUCOMA

Objetivo

To describe the 30-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).

Método

This was a retrospective, non-comparative, interventional case series in which all patients with OAG who underwent phacoemulsification with KDB between June 2018 and April 2019 were enrolled. All the participants had a minimum follow-up of 30 months. Preoperative and postoperative intraocular pressure (IOP), number of glaucoma medications, surgical complications, and any subsequent related events or procedures were recorded. Success was defined as an IOP reduction of at least 20%, or a reduction of at least 1 glaucoma medication, compared to baseline.

Resultado

A total of 30 patients (30 eyes) were included (mean age, 65.8±9 years). After a mean follow-up of 35.5±4.2 months, mean IOP was reduced from 15.9±3.5 mmHg to 13.4±2.7 mmHg (p<0.01). The mean number of glaucoma medications also decreased significantly from 2.2±0.8 to 1±0.9 at the last follow-up visit (p<0.01). On the basis of the predefined criterion (IOP reduction ≥20% and/or reduction ≥1 medication), the 30-month success rate was 86%. Most common postoperative complication was transient hyphema (30%) and IOP spike >5mmHg (17%). No sight-threating adverse event was documented.

Conclusão

Our mid to long-term findings suggest that phacoemulsification with Kahook Dual Blade goniotomy significantly reduces both IOP and dependence on IOP-lowering medications in eyes with OAG. Adverse events were not sight-threatening and typically resolved spontaneously.
