The High-Acuity device aims to provide functional central vision, to assist with tasks such as face-recognition and reading large print.

  • The implant will have an electrode array with 256 stimulating electrodes to allow patients to perceive more detailed vision. 
  • We are using diamond materials to form the electrode array and to seal the implant. Diamond is very biocompatible because it is an inert material, which minimises irritation to surrounding tissues. This means that the implant will be safe to stay in the body for the lifetime of the patient.

The first patients for the High-Acuity device will be people with retinitis pigmentosa, but we are developing the technology so it will be suitable for people with age-related macular degeneration.

A diagram showing the high-acuity device, which consists of a camera mounted on a pair of glasses which wirelessly transmits data to the retinal implant and the processor which stimulate the retina. Electrical signals are sent from the retina via the visual pathway to vision processing centres in the brain.
