Abstract
The device for expanding and maintaining of Schlemm’s canal has been developed and its application to the surgical treatment of primary open-angle glaucoma has been estimated. The titanium nickelide implant in the form of the open ended ring with the diameter of 11 mm is made as the hollow tube with multiple perforations of different sizes. The stent external diameter is 245 µm, the internal – 150 μm. The standard non-penetrating deep sclerectomy has been carried out; 1.4 % sodium hyaluronate solution was introduced into the Schlemm’s canal mouth, the bouginage of the venous sinus lumen was conducted and stent was implanted. The gross specimen examination revealed the trabecular reticulum and Descemet’s membrane integrity. In all cases, the implant was entirely in Schlemm’s canal.
