One of the most interesting new developments in medical technology is bringing human beings one step closer to realizing that the concept of a bionic man (or woman) is not so far fetched after all. Recently, a biotech company named second sight successfully engineered a bionic eye for human use. So thoroughly did it work that the company’s darling was even approved by the FDA (The United States Food and Drug Administration) for human use. Now, while the bionic eye does not completely replace a normal human eye nor allow one to see full visual images, it does allow those to whom it is successfully transplanted into to see patterns of light.
This may not sound like much but most people have always had their sight and so cannot imagine what it would be like to lose it, either in one eye or, in worst case scenarios, in both eyes. The device works by a pair of glasses that will transmit the light patterns wirelessly and directly into a retinal implant. Light is picked up via a extremely small camera that will be placed into a pair of glasses, which makes the bionic eye quite versatile. The reason for this is that it will be able to be put in to either one or both lenses of a pair of glasses such that someone with normal vision in one eye and bad to nonexistent vision in the other will remain unaffected in the eye that already sees fine. The tech from Second Sight has a long way to go before it makes a bionic eye that can meet or surpass the sight of a normal and fully functional human eye but it is now beyond question that such technology is more than possible.

While this sounds like something out of a science fiction novel that Frank Herbert would write it is something which has already been done, successfully as well. Scientists from Cornell University have already printed a fully functional human outer ear. Looking at it and having someone tell you it came from a printing machine, you would probably think they were insane. But it is more than just so much flash and spectacle, it’s a clear sign of what the future of organ and tissue transplants might hold.
