2. Implantable telescope
An implantable telescope is a tiny implantable device about the size of a pea, which magnifies images to improve central vision. The FDA approved this device in July 2010.
The device is for people who experience severe vision loss, or “end stage” macular degeneration. During the clinical trial, 59.5% of people with the telescope prosthesis experienced a doubling of visual acuity even after two years of implantation. The trial showed the substantial improvement of vision after the one year and two-year marks.
