"The Kahook Dual Blade
(KDB) device was launched in the United States in 2015 and is now available
around the globe. This has allowed the collection of real world data regarding
KDB’s utility and safety in everyday practice."

"One example of a clinical
data set involved a prospective
interventional case series of consecutive patients with glaucoma who had
phacoemulsification plus goniotomy with KDB. Of the 71 eyes included in
this study, 70% had primary open-angle glaucoma. Other diagnoses included
angle-closure, pigmentary, pseudoexfoliative, and normal-tension glaucoma.
Sixty-five percent of eyes were classified as having mild to moderate glaucoma
and 35%, severe glaucoma. The mean baseline IOP decreased from 17.4 mm
Hg ± 5.2 (SD) to 12.8 ± 2.6 mm Hg 6 months
postoperatively and the hypotensive medication use decreased from
1.6 ± 1.3 to 0.9 ± 1.0, respectively (P < .001
and P = .005, respectively). The most common observation was blood reflux
during surgery (39.4%). The authors concluded that the KDB plus
phacoemulsification resulted in a significant and sustained reduction in IOP
and a decrease in glaucoma medications after 6 months of follow-up.
The goal for inventing
the KDB device was to find a better and more efficient method for removing a
complete strip of TM using an ab interno approach while minimizing damage to
surrounding tissues. The preclinical testing and subsequent clinical data
collected to date reveal that the KDB can safely remove TM and allow for
aqueous humor egress through the distal outflow system. The documented safety
and efficacy has made KDB a valuable part of the surgical care of glaucoma
patients with disease ranging from mild to end-stage while the added
versatility of combining KDB with cataract surgery or as a standalone treatment
has made it a mainstay in operating rooms around the globe."
