The company, about its technology: The prosthetic telescope, together with the cornea, acts as a telephoto system to enlarge images 3X or 22X, depending on the device model used . The telephoto effect allows images in the central visual field ('stra ight ahead vision') to not be focused directly on the damaged macula, b ut over other healthy areas of the central and peripheral retina. This generally helps reduce the 'blind spot' impairing vision in patients wi th AMD, hopefully improving their ability to recognize images that were either difficult or impossible to see. The prosthetic telescope is implanted by an ophthalmic surgeon in an out patient surgical procedure. The device is implanted in one eye, which p rovides central vision as described above, while the non-implanted eye provides peripheral vision for mobility and navigation. After the surgi cal procedure, the patient participates in a structured vision rehabili tation program to maximize their ability to perform daily activities. S ituated in the eye, the device allows patients to use natural eye movem ents to scan the environment and reading materials.
