Abstract
A device for treating glaucoma in an eye is described.
The device includes a body defining a lumen and having first and second ends and external and lumenal surfaces, wherein the body has a length sufficient to provide fluid communication between the anterior chamber and tear film of the eye through the lumen when the device is implanted in the sclera. The device further includes a filter membrane capable of providing outflow resistance to aqueous humor flowing through the lumen. The device further includes a debris filter positioned either at the first end or between the first end and the filter providing outflow resistance. Methods of treating glaucoma wherein the device is implanted in the sclera of an afflicted eye are also described.
