Wireless prosthesis solves the problem of vision loss in the most severe cases

According to The Hindu, scientists have developed a high-resolution retinal prosthesis, using nanowires and wireless electronic systems. The prosthesis helps nerve cells in the human retina to respond to light. This technology can help millions of people with neurodegenerative diseases affecting vision.

Such diseases include macular degeneration, retinitis pigmentosa and loss of vision due to diabetes. In recent studies, the scientists have demonstrated a normal response to light in the retina of rats in which a prototype device was installed.

The prosthesis consists of a set of silicone nanowires that capture light and then stimulate the retina electrically. There is also a wireless element. It transmits power and data to nanowires through the same wireless channel. It happens with the highest speed.
