Implanting a Telescope Inside the Eye

A tiny telescope, already approved for use in Europe, can be implanted in one eye to help people with an advanced form of macular degeneration. The device takes the place of the natural lens.

From the New York Times:

A tiny glass telescope, the size of a pea, has been successfully implanted in the eyes of people with severely damaged retinas, helping them to read, watch television and better see familiar faces.

The new device is for people with an irreversible, advanced form of macular degeneration in which a blind spot develops in the central vision of both eyes.

In a brief, outpatient procedure, a corneal specialist implants the mini-telescope in one eye in place of its natural lens. The telescope magnifies images on the retina, extending them so they fall on healthy cells outside the damaged macula, said Allen W. Hill, chief executive of VisionCare Ophthalmic Technologies in Saratoga, Calif., the implant’s maker.

In March, an advisory panel to the Food and Drug Administration unanimously recommended approval of the device. VisionCare says it expects the F.D.A. to give its O.K. later this year. The device has already been approved for use in Europe.

A truly remarkable and admirable development—but rudimentary in comparison to the kinds of vision improvement technology that should be available within just another decade or two.
