Abstract:
The Kahook Dual Blade (New World Medical, Rancho Cucamonga, CA, USA) is a novel goniotomy instrument for opening Schlemm's canal. Performing the procedure is comparable to the Trabectome (Neomedix, Tustin, CA, USA) under gonioscopic control with the major difference that the trabeculectomy is created by a dual blade instead of electroablation. The currently available clinical data are limited to a small number of retrospective studies with ≤1 year of follow-up. Based on these data and in line with the author's personal experience, the Kahook Dual Blade seems comparable to the Trabectome regarding effectiveness as well as intraoperative and postoperative complications, such as intraocular pressure (IOP) elevation and hyphema.
