Reflections from a 4-Year Canadian Study: Advancing Glaucoma Surgery with the Kahook Dual Blade

At Labtician, we are committed to providing glaucoma specialists with cutting-edge insights and innovative surgical solutions for improved glaucoma management. Our latest white paper, “Reflections from a 4-Year Follow-Up Study: Insights from Canadian Glaucoma Surgeons on the Kahook Dual Blade Goniotomy,” delivers robust long-term clinical outcomes that highlight the significant benefits of the Kahook Dual Blade (KDB) in glaucoma surgery.

Study Overview: A Canadian Multicentre Retrospective Analysis

This comprehensive study followed 108 eyes from 89 patients who underwent KDB goniotomy in conjunction with phaco-emulsification, over four years. Provided real-world evidence of KDB’s effectiveness in promoting disease stability, irrespective of disease severity, while significantly enhancing patients’quality of life both short and long term, by lowering intraocular pressure (IOP) and reducing the glaucoma medication burden. Esteemed Canadian experts—Dr. Paul Harasymowycz, Dr. Oscar Kasner, Dr. Steven Schendel, and Dr. Ali Salimi—clinically reviewed the study.

Key Clinical Insights for Glaucoma Specialists

• Sustained IOP Reduction:
 The average IOP dropped to 14 mmHg—a 26% reduction—with 46% of patients maintaining an IOP below 12 mmHg, even though 62% of the study cohort presented with moderate to advanced glaucoma. This significant IOP reduction reinforces KDB as a powerful tool in glaucoma surgery.
• Decreased Medication Burden:
 A considerable number of patients experienced a reduction in their reliance on glaucoma medications, with nearly 25% becoming completely medication-free postoperatively. This improvement in glaucoma treatment outcomes supports a shift toward more sustainable glaucoma management strategies.
• Excellent Safety Profile:
 KDB goniotomy demonstrated a favorable safety profile with transient, non–sight-threatening adverse events. By utilizing an implant-free, minimally invasive approach, the Kahook Dual Blade minimizes long-term complications that are often seen with implant-based MIGS devices.
• Cost-Effectiveness and Versatility:
 The study underscores KDB’s simplicity, affordability, and ease of integration into diverse surgical settings. Its design makes it accessible to both comprehensive ophthalmologists and glaucoma specialists, thereby enhancing access to effective glaucoma surgery and treatment options.

Why Choose Kahook Dual Blade Goniotomy for Glaucoma Surgery?

The findings from the Pan-Canadian 47-month multicentre study confirms that KDB goniotomy offers strong anatomical and functional outcomes in glaucoma surgery. By precisely excising the trabecular meshwork without leaving any implant behind, the Kahook Dual Blade significantly reduces IOP and the need for glaucoma medications, while minimizing risks such as bleb-related complications or device malpositioning.

For glaucoma specialists focused on delivering superior patient care, the Kahook Dual Blade represents an innovative and cost-effective surgical option that advances glaucoma treatment and management.
