1. A device for treating glaucoma in an eye, the device comprising:

  • a body defining a lumen and having first and second ends and external and lumenal surfaces, said body having a length sufficient to provide fluid communication between an anterior chamber and a tear film of the eye through said lumen when said device is implanted in the eye such that;

    (i) the first end is in the anterior chamber, (ii) the second end is exterior to the eye, and (iii) a portion of the external surface of the body is in contract with a sclera of the eye,wherein the lumen is circular and open from the first end to the second end and configured to maintain a desired intraocular pressure without having a porous element inside the lumen,wherein the portion of the external surface of the body that is in contact with the sclera of the eye while the device is implanted in the eye is chemically etched to provide increased friction with the sclera and includes two pairs of barbs extending in opposite lateral directions from the body,wherein a portion of the body including the second end is laterally flared and includes a surface shaped to follow an outer contour of the eye, andwherein the first end is beveled.
