KDB Dual Blade Goniotomy
The KDB Procedure and Candidates
KDB is used under gonioscopic visualisation through a temporal clear corneal incision. Typically 90–120 degrees (1–2 clock hours) of angle are treated. KDB is most commonly performed in combination with phacoemulsification (phaco-KDB), which deepens the anterior chamber and improves angle visualisation. Candidates: mild-to-moderate primary open-angle glaucoma, pseudoexfoliation glaucoma, pigmentary glaucoma. Outcomes: approximately 20–30% IOP reduction and reduction of 1 medication at 12 months.
Clinical Application at Suraj Eye Institute
At Suraj Eye Institute, KDB is offered as part of our MIGS portfolio for appropriate glaucoma-cataract combination cases, combining minimally invasive principles with precise trabecular meshwork anatomy understanding.
Our surgeons are proficient in gonioscopic technique and the microsurgical precision required for KDB insertion and advancement. We integrate KDB with cataract surgery when appropriate to maximize glaucoma benefit while addressing visually significant cataracts, ensuring comprehensive management of combined glaucoma-cataract cases.
