Abstract:
1. An ophthalmic implant for treating or alleviating the symptoms of glaucoma, the implant having: (a) a plate shaped to fit the surface of an eye when implanted, (b) an inner ridge located on the upper surface of the plate, where a region encompassed by the inner ridge defines a primary drainage region into which fluid from the anterior chamber or posterior chamber of the eye can be drained when in use, (c) a boundary structure located on the upper surface of the plate outward of the inner ridge, provided that the height of the inner ridge relative to the surface of the plate is greater than the height of the boundary structure relative to the surface of the plate, (d) a secondary drainage region outside the inner ridge into which fluid from the primary drainage region can be received when in use, where the secondary drainage region is defined by the inner ridge and the boundary structure, and (e) a hole in the inner ridge having a size enabling a drainage tube for draining the fluid from the anterior chamber or posterior chamber of the eye to the primary drainage region to be connected to the hole so that fluid can be transferred through the tube and into the primary drainage region.
