Bionic eye for a patient with retinal macular degeneration
The Briton got his eyesight back with the help of an artificial eye
80-year-old patient Ray Flynn completely lost his central vision due to dry macular degeneration of the retina, but doctors managed to restore the patient's ability to see thanks to a 4-hour operation. The man was fitted with an Argus II prosthesis – a bionic eye that receives an image from a miniature video camera mounted on special glasses, then converts it into electrical impulses. These pulses wirelessly arrive at the electrodes attached to the retina of the eye, then the information is sent to the brain.
The implant does not give the patient the possibility of acute vision – but now Ray Flynn sees the outlines of people and objects in front of him. Previously, instead of the central objects in front of him, the man saw a black spot, and therefore he had to constantly use the possibilities of peripheral vision. One of the unusual properties of the bionic eye is that it allows you to see even with your eyes closed.
The Argus II bionic eye was created by the American company Second Sight. Previously, the implant was transplanted only to patients suffering from retinitis pigmentosa, a rare degenerative eye disease. Now the Royal Manchester Hospital is planning to conduct 4 more free surgeries for elderly patients with the same ailment as Ray Flynn.
