How the IMT Works

Age-related macular degeneration (AMD) affects a part of the retina called the macula.  The macula is responsible for "straight ahead" detailed vision, which allows you to perform everyday tasks such as reading, watching television, recognizing faces and colors, and seeing objects in detail. 

As AMD progresses, the macula becomes more and more damaged and you begin to lose your central vision. People with AMD generally continue to have peripheral or side vision.

Your condition is described as end-stage AMD when the macula has lost all function and a physician considers your condition to be untreatable.

The Implantable Miniature Telescope or IMT is a tiny telescope about the size of a pea that is implanted in one eye.  It magnifies objects and projects them onto the healthy parts of the retina. This means that objects are highly magnified, allowing your implanted eye to provide central vision. The other eye provides peripheral vision.
