Diane Ashworth, a patient in Australia with severe vision loss due to retinitis pigmentosa, has received a functioning bionic eye implant earlier this year. Australian researchers have developed a bionic eye that consists of 24 electrodes implanted into the retina. The electrodes send signals to nerve cells in the eye to allow for vision. Currently, the prototype only allows for partial vision restoration but researchers hope to further develop the eye to allow for full images to be assembled using flashes of light.
