The WA-NG telescope prosthesis (Figure 1) is the next generation telescopic implantable device which, when combined with the optics of the cornea, constitutes a telephoto system for improvement of visual acuity in patients with severe to profound vision impairment due to bilateral, end-stage age-related macular degeneration. The device is implanted in one of the patient's eyes. In this way, the implanted eye provides central vision and the non-implanted eye can continue to provide peripheral vision.
Patients will be screened for eligibility and informed consent will be obtained from those who meet screening criteria and are interested in participating in the study. Eligible patients will be examined preoperatively to obtain a medical history and to establish a baseline for ocular condition. Baseline measurements will include successful use of an external telescope.
Postoperatively, patients will undergo ophthalmic evaluation at regular intervals as specified in this protocol and will be required to return for 6 to 10 additional visits for vision training with a low vision specialist.
