b. What is the indication for its use?
Answer aImplantable miniature telescope. Answer b Image magnification for age-related macular degeneration. It is implanted likes an intraocular lens following lens extraction. The magnified effect allows images in the central visual field not be focused directly on the damaged macula, but over other healthy areas of the central and peripheral retina. This helps to reduce the 'blind spot' impairing vision in patients with macular degeneration. The unimplanted eye provides peripheral vision for navigation.
