A 2.5 X magnification system consisting of a two-zone intraocular implant and a spectacle was developed, tested, and clinically tried by fifty patients with cataract ad age-related macular degeneration. Optical bench testing results and clinical data confirmed that the field of view of the system was 2.6 times wider than an equivalent external telescope. The study also demonstrated that the implant itself was clinically equivalent to a standard monofocal intraocular lens for cataract. The clinical study indicated that higher magnification without compromising the compactness and optical quality was needed as the disease progressed. Also, a sound vision rehabilitation process is important to provide patients the full benefits of the system.
