The present invention is a device that is used for glaucoma management by using an adjustable shunt that drains the aqueous humour from inside the eye in a precise way. This new device has a valve that prevents back flow of the drained fluid and that decreases the risk of hypotony, and also this device has an intraocular pressure indicator. In addition to the main device, there is a small device that is implanted throughout the iris, in order to shunt aqueous humour from posterior chamber to anterior chamber of the eye.
