Raised eye pressure in open angle glaucoma is usually controlled using drops. Patient compliance and the ability of drops to lower eye pressure are essential for successful glaucoma control. However, drops may cause side-effects such as dry eye, discomfort or irritable eyes. In addition, drops may not be able to sufficiently lower eye pressure. Fortunately, minimally invasive glaucoma surgery combined with routine cataract surgery is an effective alternative in the management of raised eye pressure. In most glaucoma cases, raised pressure occurs as a result of increased resistance at the trabecular meshwork which is the drainage area where aqueous fluid leaves the eye. Minimally invasive glaucoma surgery involves placing a tiny stent into the trabecular meshwork to increase the outflow of aqueous fluid. The stent is one of the smallest medical devices to be implanted into the human body. The stent is a titanium tube less than a millimetre long which safely lowers eye pressure by creating a permanent by-pass of the trabecular meshwork. The procedure to implant the stent involves numbing the eye, a special lens is then positioned on the eye to allow the surgeon to view the drainage area. A small injector is then passed through a tiny opening and two stents are implanted into the trabecular meshwork. The stent procedure does not carry any additional risks to routine cataract surgery and there is a very good chance that your daily drops will be reduced and you will not require major glaucoma surgery which generally carries greater risks.
