[Minimally invasive angle surgery. The Trabectome].

The Trabectome provides a new perspective in angle surgery for open angle glaucoma. Through a 1.7 mm clear cornea tunnel, the juxtacanalicular meshwork is electroablated under gonioscopic control. Thereby, the collector channels in the outer wall of Schlemm's canal are uncovered and resistance to trabecular outflow is removed. From the literature and from our own experience, a pressure reduction by 30-35% can be achieved with a simultaneous reduction of eye drops by 50%. The Trabectome can conveniently be combined with phako-emulsification. Serious complications have not yet been reported. As the conjunctiva remains completely untouched, trabeculectomy, if necessary, could be performed without prognostic restrictions. With a realistic target pressure of approximately 16 mmHg, Trabectome surgery is indicated in patients with moderate optic nerve damage.
