Abstract: A drainage device for use in an eye to drain aqueous humour so as to reduce intraocular pressure or for treating glaucoma. The device has a multi-lumen tube having a first end, a second end opposite the first end, and a plurality of lumen extending between the first end and the second end. At least one of the lumen is sealed at the first end. A flow through the multi-lumen tube is adjusted by forming at least one aperture open in one of the lumen through a wall of the tube and/or sealing at least one aperture open in one of the lumen. The tube has a longitudinal axis through the first end and the second end, and an outer surface extending between the first end and the second end. A cross-section perpendicular to the longitudinal axis has a non-circular shape at the outer surface with an aspect ratio of at least 3:1.
