Can a blind man see with a bionic eye?

  • A 73 year old person has regained his eye sight and is able to see through a bionic eye fitted in a rare surgical event conducted by British doctors.
  • The doctors at the Moorfields eye hospital in London led by Lyndon da cruz had conducted the surgery 7 months back on Ron wbo lost his vision 30 years ago.
  • The bionic eye known as Argus II developed by US company "second sight" uses a camera and video processor mounted on sun glasses to send captured images wirelessly to a tiny receiver on the outside of the eye. In turn, the receiver passes on the data via a tiny cable to an array of electrodes which are fitted on the retina - the layer specialized cells that respond to light at the back of the eye. When these electrodes are stimulated they send messages through the optic nerve to the brain.
  • According to the doctors the implants have been stable with consistant visual perceptions generated by the device.
  • This surgery is a very good step forward in treating patients with total vision loss due to retinitis pigmentosa.
  • This wonderful discovery of science has really brought a hope for the visually impaired to see this beautifull world again. Source: BBC News
