Bionic Eye Restores Vision for Blind Man After 40 Years

Doctors have given a man his sight back, implanting a bionic eye in Texan resident John Jameson to restore some of his vision after some 40 years of blindness.

Four decades ago, an aggressive infection took Jameson’s sight, and it was his wife who discovered the possibility of installing a bionic eye – a type of operation that has only recently been approved by the Food and Drug Administration (FDA) in the US.

John Jameson saw the world through normal eyes until a histoplasmosis fungal infection caused his vision to blur. A follow-up laser surgery to reverse the fungal infection damaged his vision even further, leaving him legally blind. After 40 years of limited vision, however, Jameson now can see again thanks to a breakthrough eye telescope and fine surgical work by Dr. Christopher Shelby of the WK Eye Institute.

Developed by Dr. Isaac Lipshitz of VisionCare, the Implantable Miniature Telescope was designed for those suffering from age related macular degeneration, a common and debilitating eye disease that results when the retina begins to deteriorate. Macular degeneration is the leading cause of vision loss in the U.S., affecting more than 10 million Americans. Though Jameson didn’t suffer from that condition, the fungal damage to his eye was similar, making him an ideal candidate for the eye surgery.

The operation involved the implantation into the eye of a miniature Galilean telescope containing wide-angle micro-optical lenses. The mini telescope is implanted into one eyeball, replacing the lens, which is removed during the surgery. Working along with the cornea, the telescope can enlarge images to approximately 2.2 to 2.7 times their average size. This magnification allows the images to project onto the healthy parts of the retina, bypassing the damaged blind spot and restoring some of the patient’s vision.

Jameson successfully underwent the implant surgery and is currently undergoing therapy to adjust to his newly improved eyesight.

Jameson’s telescope is not the only bionic eye to have become available in the past couple of years; an alternate system called Second Sight works by implanting electrodes onto the retina which connect to exterior glasses that work as a ‘camera’ and send signals to the brain.

A 58-year-old woman named Carmen Torres has become the first person in the US state of Florida to have a bionic eye installed. The device has already allowed her to see light and basic shapes for the first time in 13 years, and with further training she’ll be able to view the world in even more detail.

Torres was diagnosed with retinitis pigmentosa when she was 18, a condition that gradually causes the light-sensing rod cells in the eye’s retina to die off, and over time this severely deteriorates vision. By the age of 45, Torres was declared legally blind, and couldn’t see her own face in the mirror anymore.
