A miniature telescope implanted into the eye could soon help people with vision loss from end-stage macular degeneration. Clinical trials of the device, which is about the size of a pencil eraser, suggest it can improve vision by about three and a half lines on an eye chart.
The implant, developed by VisionCare, consists of two lenses within a small glass tube. Once inside the eye, it works like a fixed telephoto lens, acting in conjunction with the cornea to project a magnified image of whatever the wearer is looking at over a large part of the retina.
