New bionic eye allows blind people to see the light again with microchip

A bionic eye capable of restoring blind vision is undergoing groundbreaking testing.
A microchip on the back of this bionic eye helps the blind to "re-see the light" and let them see the clock hands and everyday objects again. In the test, a male patient saw his girlfriend's smile for the first time, and another subject could see his name. It is reported that this device can even be applied to some types of natural blindness.
Ophthalmologists used "very surprising" to describe the test results, and the first British patients will be the beneficiaries of this technology within a few months. Experts say that this subretinal implant device can revolutionize the treatment of blindness, just as cochlear implants change the lives of deaf people. The first beneficiaries will be those with retinitis pigmentosa. Retinitis pigmentosa is a hereditary disease that gradually destroys the retina and eventually leads to complete blindness. In addition, bionic eyes can also be used to treat aging-related macular degeneration, the most common cause of blindness in the elderly. The number of patients with retinal macular degeneration who are currently unresolved in the UK is around 500,000.
Robert McLaren, a professor of ophthalmology at Oxford University, said: "I can make them hopeful when discussing eye diseases with patients, at least for some types of eye diseases. This device makes them easier to deal with terrible. The prognosis that leads to their blindness."
Developed by the German company Retina Implant AG, this bionic eye consists of a 3 mm x 3 mm microchip and 1500 light sensors. The role of the light sensor is to replace the retina that has lost its function due to disease. Compared to previously developed bionic eyes, Retina Implant's battery-powered bionic eye eliminates the need for bulky accessories, such as cameras mounted on dark glasses, for the first time in the history of bionic eye research.
According to the British Royal Society Association B, the implantation of bionic eyes has helped two male blinds and one female blind person to see objects for the first time after blindness due to retinitis pigmentosa. Within a few days, all three patients were able to see objects placed on the table, including a cup of tea tray. After this, more patients receive this treatment.
Dr. Eberhard Zelena, founder and researcher at Retina Implant, said: "A young patient told me that he saw his girlfriend and saw her smile. Another patient suddenly saw it while sitting in the garden. The outline of a sunflower. Other patients saw the insects crawling on the glass and seeing the white lines left by the plane in the sky. Their lives are rejuvenated and happy."
McLaren plans to test the bionic eye in the UK in early 2011, and he used "very surprising" to describe the test results. The ophthalmologist said: "Until recently, this idea has been regarded as a science fiction. Although the bionic eye can only give patients basic vision, what we hope to do is to enable people who have completely lost their vision to The next person does not use the guide dog."
It is reported that the cost of this equipment is between 20,000 pounds and 45,000 pounds (about 32,000 US dollars to 72,000 US dollars), which is comparable to the cost of training a guide dog. However, this bionic eye is not suitable for all types of blindness, and more work needs to be done before widespread use – it is expected to be widely used within 5 years. McLaren said: "We still face many problems, such as how long the chip can be used and how to improve it. But there is no doubt that this research will make rapid progress."
