The Implantable Miniature Telescope (IMT) is a device that can be implanted inside the eye for those affected by end-stage age-related macular degeneration (AMD). It sits in place of a lens and magnifies images onto healthy areas of the retina to improve central vision.

Milestones

  • 2020: CE mark approval
  • 2010: FDA approval

Background

The IMT is a fixed-focus, monocular prosthetic telescope that can be surgically implanted into those affected by AMD. In the patient's most qualified eye, the lens is removed, similar to that of cataract surgery, but instead of a new lens, the IMT is placed right behind the iris. Once implanted, the telescope enlarges objects in the patient's central visual field and focuses them onto healthy areas of the retina. This eliminates peripheral vision in the implanted eye, which is why it is only implanted monocularly. For peripheral vision, the patient must rely solely on that from the non-implanted eye. The dimensions of the IMT are 4.4 x 3.6 mm. There are two models currently available, one with 2.2x magnification and one with 2.7x magnification. The IMT itself is made of three primary components: a glass capsule that contains wide-angle micro-optical elements, a clear polymethylmethacrylate (PMMA) carrier, and a blue PMMA light restrictor (to prevent peripheral light from entering the eye).
