Legally Blind Can See With Bionic Eye

The bionic eye was dramatically improved in 2014, allowing the legally blind to do finally see, as they had long dreamed. Larry Hester was one of those to have his life dramatically changed by the bionic eye in 2014 when, after nearly 33 years of blindness, his sight was restored thanks to the bionic eye.

The bionic eye, known as the Argus II Retinal Prosthesis System, was approved by the FDA in 2013, but this year engineers further improved its visual system. It is the world’s first implanted device to treat people with retinitis pigmentosa, one of the leading causes of blindness. The bionic eye consists of a device implanted into the eye, a video camera in a pair of glasses, and a video processing unit carried by the patient. For now, Hester is only able to see light again, but for the 66-year-old tire salesman, it’s more than expected.

The light is so basic and probably wouldn’t have significance to anybody else. But to me it’s meaning I can see light. And we can go from here,” he said.

Heart Transplant From A Cadaver

When it comes to body transplants, it’s pretty much a necessity that the donor is alive, but this year all that changed. In October, a team of Australian scientists made history when they revived dead hearts from cadavers and successfully transplanted them into awaiting patients.

About 20 minutes after the hearts had stopped beating, doctors put them inside a machine, dubbed the “heart in a box,” which supplied the vital organ with oxygen. After removing the heart from the box it was injected with a preservation solution, designed to keep it fresh. This was done thanks to a perfusion-based machine, named OCS-HEART.



“So those two things coming together [the console and preservation solution] almost like a perfect storm, have allowed this sort of transplantation of a heart that's stopped beating to occur," Professor Bob Graham, executive director of the Victor Chang Institute, the facility behind the preservation solution, told ABC News.
