The ability to give sight to a blind person via a bionic eye depends on the circumstances surrounding the loss of sight. For retinal prostheses, which are the most prevalent visual prosthetic under development (due to ease of access to the retina among other considerations), patients with vision loss due to degeneration of photoreceptors (retinitis pigmentosa, choroideremia, geographic atrophy ...
Argus retinal prosthesis, also known as a bionic eye, is an electronic retinal implant manufactured by the American company Second Sight Medical Products. It is used as a visual prosthesis to improve the vision of people with severe cases of retinitis pigmentosa .
"State-of-the-art" retinal implants incorporate 60-100 channels, sufficient for basic object discrimination and recognition tasks. However, simulations of the resultant pixelated images assume that all electrodes on the implant are in contact with the desired retinal cell; in reality the expected spatial resolution is lower, as a few of the ...
An optometrist in British Columbia claims to have invented an easily implantable device that provides its wearer with vision "three times better than 20/20" for life. Dubbed the Ocumetics Bionic ...
Not all patients experienced the same degree of improvement, however. The 12 Iranian patients wound up with an average visual acuity of 20/58 with glasses; functional vision is defined as 20/40 or ...
In September, doctors implanted a small device into Hester's left eye. The instrument, an Argus II Retinal Prostesis Device, consists of the implant, a video processor, and a pair of glasses that ...
[6] [17] There are several theories of improved eye movement, such as using integrating prosthetic material, pegging the implant, covering the implant (e.g. with scleral tissue), or suturing the eye muscles directly to the prosthetic implant. The efficiency of transmitting movement from the implant to the prosthesis determines the degree of ...
A mother in Colorado was recently given the gift of sight with the help of new technology that allowed her to see her son for the first time in years.
