The world's first approved device intended to restore vision for people suffering from blindness.

Key Features of Argus® II

The Argus II Retinal Prosthesis System ("Argus II") is the world's first FDA approved device intended to restore some functional vision for people living with blindness due to severe to profound retinitis pigmentosa. Moreover, it offers the following benefits:

  • Most clinical experience of any retinal prosthesis ever developed
  • Improvements in ability to perform visual tasks demonstrated in many patients
  • Upgradable external hardware and software to benefit from future innovations
  • Minimal time from implantation to first system use and use at home
  • Implant is MR conditional (VPU and glasses are MR unsafe and should not be worn inside an MR system room)
  • Video processor with adjustable settings for individual preferences, for example:
    • Edge enhancement
    • Contrast enhancement
  • 20° maximum possible field of view
    • Can be compared to a 30 cm ruler held out at arm's length
  • Audible signals that provide information on system functionality


HUMANITARIAN DEVICE: Authorized by Federal (U.S.) law to provide electrical stimulation of the retina to induce visual perception in blind patients with severe to profound retinitis pigmentosa and bare light or no light perception in both eyes. The effectiveness of this device for this use has not been demonstrated.
