New tech surgery aids recovery of vision
A blind woman in China has recovered partial vision after receiving a brain-computer interface surgery in Changsha, Hunan province, bringing new hope to patients suffering from degenerative retinal diseases.
Chen, 61, was diagnosed with retinitis pigmentosa at the age of 40, a condition that eventually left her completely blind in both eyes. On April 23, she was selected for a clinical trial and underwent an implantation surgery at Xiangya Hospital of Central South University.
During the surgery, an electrode array measuring 6 millimeters by 10.8 mm — roughly the size of a fingernail — was implanted onto the retinal surface of the macular region inside the eyeball.
