The Ahmed ClearPath glaucoma drainage device has been commercially launched in the United States. Available in 350 mm2 and 250 mm2 sizes, the implant includes a flexible plate with a contour that conforms to the curvature of the eye and suture fixation points positioned more anteriorly on the device in comparison to other valveless drainage devices. It is designed to address tube shunt surgery challenges and comes with an optional pre-threaded ripcord and a 23-gauge needle. One feature of the Ahmed ClearPath implant is a flexible plate with a contour that closely conforms to the curvature of the eye. In addition, the suture fixation points are positioned more anteriorly on the device compared to other valveless drainage devices. By making the suture points more visible and accessible, the company said the surgeon may find securing this implant to the eye more convenient. The device or procedures are reserved for mild to moderate glaucoma cases.
