Kahook Dual Blade (KDB) goniotomy is a highly effective and sustained treatment for reducing intraocular pressure and medication burden in Black and Afro-Latinx patients with all types and severities of glaucoma, including advanced stages, according to a study.
Researchers retrospectively reviewed surgical outcomes in 90 eyes from 90 adult patients who underwent KDB goniotomy, either alone or combined with cataract surgery. All glaucoma subtypes and severity levels were included, with follow-up extending to 20 months.
There was a sustained and significant reduction in intraocular pressure (IOP) at all time points, with mean postoperative IOP ranging from 12.9 to 13.5 mmHg—over 31% lower than baseline. Medication use also dropped by an average of 2 agents by month 20. Surgical success, defined by reduced IOP or fewer medications, was achieved in over 95% of patients throughout the study.
The authors advocate for broader use of minimally invasive glaucoma surgery (MIGS) like KDB in underserved Black and Afro-Latinx communities globally.
