Zusammenfassung

Das Kahook Dual Blade (New World Medical, Rancho Cucamonga, CA, USA) ist ein Instrument zur Eröffnung des Schlemm-Kanals. Die Anwendung erfolgt wie beim ähnlich funktionierenden Trabektom (Neomedix, Tustin, CA, USA) unter gonioskopischer Kontrolle. Die Studienlage beschränkt sich auf einzelne retrospektive Studien mit Nachbeobachtungszeiten von bis zu einem Jahr. Anhand dieser Daten und nach eigenen Erfahrungen scheinen der drucksenkende Effekt und das Komplikationsprofil vergleichbar dem Trabektom zu sein. Die persönlichen Erfahrungen der Autoren mit dem Instrument sowie Details der Operationstechnik werden diskutiert.

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.
