It is light again with help of bionic eye implant for an old man. He can now identify with his family after decade.
Zderad Allen was totally blind due to retinitis pigmentosa and had to do away with his career.
He did wood working for earning a living by the spatial awareness and sense of touch
Retinitis pigmentation is a condition that is normally inherited and it degenerates given type of cells called photoreceptors and can do away with entire vision.
Zderad new eye plant work under the principles of bypassing the destroyed retina and sending light wave signals directly to the optic nerve. 60 point of simulation are given by small chip with many electrodes at the back of the eye.
Mr. Zderad is undergoing artificial vison due to the several passes of electrical signals he receives.
The available number of the flashes of light are 60, Zderad may not read or se detailed faces but can easily move in the crowded zone minus cane.
“Mr. Zderad is experiencing what we call artificial vision,” explains Dr. Iezzi. “It’s not like any form of vision that he’s had before. He’s receiving pulses of electrical signal that are going on to his retina and those are producing small flashes of light called electro-phosphenes. These small flashes of light are sort of like the points of light on a scoreboard at a baseball game.”
There are only 60 of these flashes of light, but it is enough for Zderad to reconstruct scenes and objects. Although he will not be able to see the details of faces or read, Mr. Zderad will now be able to navigate through crowded environments without the use of a cane, significantly improving his quality of life.
