Bionic eye restores partial vision in US woman
WASHINGTON: US scientists have successfully restored partial vision in a 50-year-old woman, diagnosed with blinding disease at the age of 13, with the help of an electronic eye implant.
The bionic eye was developed by Second Sight under the lead of Dr. Mark Humayun.
It is a component of the Argus II Retinal Stimulation System and is designed to stimulate retinal cells directly.
Argus II comprises three components: the implanted part, which is placed inside the patient’s eye; a tiny camera and transmitter, mounted on a pair of sunglasses; and a wireless microprocessor and battery pack, to be worn on a belt.
The implant itself contains 60 tiny electrodes that are attached to the retina via a micro-wire roughly the width of a human hair. These administer electrical impulses to retinal cells, allowing the brain to perceive light.
