After over two decades of research and development period, a company managed to make a bionic eye tool for people who experience blindness due to degenerative damage.
"This discovery marked the beginning of an era in which vision can be restored to a level that is more amazing," said Robert Greenberg, president and CEO of Second Sight, California-based company that developed this tool.
As quoted from the Technology Review site, a tool called Argus was sold for U.S. $ 115 thousand aliases around Rp1 billion. This tool is equipped with a camera mounted on his glasses and an implant is implanted near the patient's retina.
The camera will transmit the image signal to the chip implant that would stimulate the retinal cells and produce light in the eye of the patient.
This tool will help people who suffer from retinitis pigmentosa, or a defect of vision due to damage photoreseptor or part of the eye that captures light.
For now the Argus II, which uses 60 electrodes in the implants, which can only restore vision is limited.
"Patients can map and identify simple objects, such as seeing people in front of them, and follow the direction of movement," said Greenberg.
In addition, patients can also be expected to identify doors, windows, follow a line, or read the large, slowly.
However, according to Director of Institute for Research University of Tubingen Germany Ophtalmic, Eberhart Zrenner, bionic vision provided by the Argus II is an important achievement.
However, Zrenner, who also founded the company Retinal Implants AG, said currently developing a similar tool. However, using more than 1500 electrodes by utilizing the light-sensitive photodiode, rather than using the camera.
Excellence is the Argus II implant may take longer to be planted in the body. This tool has been tested on 30 patients. "We've done things that were previously considered impossible," said Greenberg.
