Abstract

The present invention relates to an ocular implant, particularly a glaucoma stent.It is the object of the present invention to devise an ocular implant which allows the ocular eye pressure to be regulated, i.e., to be maintained at a desired level, while preventing the flow resistance from increasing over time, for example due to fibrosis.In order to achieve this object, the ocular implant according to the invention comprises a small tube (5), the wall surface (3) of which encloses a hollow duct that is open on both sides in the longitudinal direction of the hollow duct, wherein a first opening (1) allowing ocular humor to flow in and a second opening (2) allowing the ocular humor to be discharged is provided, and wherein the wall surface (3) is formed by a liquid-tight material, and wherein at least one pressure-controlled valve (4) is disposed in the area of the wall surface (3).
