The invention relates to a stainless steel device for permanent insertion into the sclerocorneal limbus, with different drainage and anchorage systems, enabling the aqueous humour to discharge through one or more virtual spaces from the anterior chamber to an intrascleral space in cases of simple glaucoma or to the equatorial episclera in cases of complex glaucoma, such as neovascular glaucoma. The space is virtual, not real, as in the case of the tubular device. It enables the aqueous humour to discharge slowly and continuously, minimizing the possibility of the chamber being flat or of germs penetrating through the device. Furthermore, the anchorage system is less aggressive, thus reducing the possibility of bleeding.
