Stanford scientist's eye implant is helping blind people read again

Key Points:

• A prosthetic retinal implant the size of a pencil point has helped dozens of blind adults in Europe regain some vision, enabling activities like painting, recognizing faces, and reading.
• The device, invented by Stanford ophthalmologist Daniel Palanker and now manufactured by Science Corp, targets age-related macular degeneration (AMD), a common cause of blindness in older adults.
• Clinical trials in Europe showed significant improvement, with 27 out of 32 patients able to read again and an average vision improvement of five lines on an eye chart; regulatory approval in Europe is expected this summer.
• The implant uses a solar panel-covered disc placed behind the retina, activated by special glasses that project near-infrared images, converting them into electrical signals the brain can interpret as vision.
• While U.S. FDA approval is still in progress, the technology offers hope for restoring sight to those with advanced vision loss, and ongoing research aims to enhance resolution and expand treatment to other blindness conditions.
