Eye implant can restore some vision in rare cases
WASHINGTON (AP) - Patients who have lost their sight due to a rare disorder may be able to regain some vision using a new implantable device that takes the place of damaged cells inside the eye.
The Food and Drug Administration approved the Argus II Retinal Prosthesis System as the first treatment for an inherited disorder that causes the breakdown of cells in the retina, a membrane inside the eye.
FDA says that while the device will not fully restore patients' vision, "it may allow them to detect light and dark in the environment."
The system includes a small video camera and transmitter mounted on a pair of glasses. Images from the camera are processed into electronic data that is wirelessly transmitted to electrodes implanted into the patient's retina.
