The British Peter Ryan once thought that he could no longer see the light. But with the help of the "bionic eye", his vision is recovering. The world that has not been seen for more than 20 years is gradually becoming clear in the eyes of Ryan. Ryan is 51 years old and is the father of two children. In his 20s, he developed retinitis pigmentosa, his vision began to diminish, and he eventually became completely blind. Earlier this year, Ryan underwent a 4-hour operation at the Manchester Eye Hospital to implant an electronic signal receiver in the eye. After a two-month recovery period, he began experimenting with bionic eyes. At the beginning of this month, the long-lost world appeared in his eyes. “The images I saw were a little shaken and needed to adapt slowly. But I could see the cars, they look like cotton wool,†the British “Daily Mail†quoted Ryan’s report. Ryan can also recognize the simple words that doctors cast on the big screen. "It’s wonderful to see letters and words on the screen after a long darkness!" Bionic system Ryan’s return to light is also due to the bionic eye system. This set of bionic eyes consists of multiple parts such as a camera and an image processor. When working, the camera is first captured by the camera mounted on the glasses, and then the image is transmitted to the image processor worn by the user, converted into an electronic signal, and then returned to the transmitter on the glasses. The transmitter wirelessly transmits these electronic signals to the receiver and electrode panels on the user's retina, which activates the retinal nerves and sends signals through the optic nerve to the brain. In this way, the user can "see" the world. "At home, I can move without this pair of glasses because I know where the furniture is placed," Ryan said. "But when I go out, this pair of glasses gives me confidence and makes me independent." Initial test The bionic eye device was developed by Second Sight, and only 11 doctors worldwide have the relevant technology. Ryan is one of the first 32 biomimetic eye trial participants in the world, "it's exciting to be part of the trial," he said. Two patients who were treated at the same hospital as Ryan also made good progress: one of them was blinded to fireworks 40 years later, and the other recognized the letters. Ophthalmology hospital expert Paul Stangart said: "The patient is recovering quickly, beyond our imagination. Although there are still many things to be done, the current situation is encouraging." Ryan’s younger brother, John, said: “What the doctor does doesn’t sound incredible. I think it’s great.†Ningbo DOKEE Medical Technology Co., Ltd. , https://www.dokeemedical.com
