In recent years, our medical science has reached a level where it can invent incredible things. And now it has occurred to us that there are implants that can restore sight and hearing. The most famous ear implant is the cochlear implant. The difference between implants and hearing aids is significant. Hearing aids amplify sound, whereas implants stimulate the auditory nerve . They use a microphone to record sounds from the environment. They are used primarily in children.

Although hearing cannot be completely restored, some people can become so accustomed to hearing that they can make phone calls with the implants in place. In our country, about 50 implants were performed in 2008 alone. It is very important that patients learn how to use their implants correctly. For some people, having implants in both ears improves their ability to distinguish the direction and type of sound. As with anything, there are factors that can affect the effectiveness of the implants. These include the condition of the cochlea, the degree of hearing loss, and other diseases. With regard to vision, there are artificial lenses that can focus on different distances.

In our country, the first operation was performed five years ago. As a microchip, a smart lens was created to measure sugar levels, mainly in diabetics. Eventually, however, they will also be used for people suffering from presbyopia. Bionic eyes (artificial eyes) are already being applied in medicine. It is being promoted as a first step toward treating blindness. Implants to restore hearing have always been at the forefront, and now eye implants are also proving successful. We may even see retinal implants. The condition for their use is to preserve the function of the optic nerve. They also respond to daylight. The cost of the implant surgery starts at 20,000 yen. However, the surgical process is very quick and smooth, and the patient begins to see almost immediately.

Besides implants that restore hearing and vision, there are other implants that are helping the majority of the population today. So let\’s be surprised what scientists and medicine will come up with next.
