An interesting article from the most recent issue of Optics and Photonics News discusses ophthalmic prosthetic devices to help those who suffer from diseases that cause loss of eyesight:
"Ophthalmology has made incredible strides in the past decade in surgical vision correction and disease diagnosis—yet those facing complete blindness have remained largely without hope. Now, however, scientists and surgeons have begun accomplishing the seemingly impossible: restoring sight to those who had lost it.
After 25 years of development, optics and optoelectronic technology in the form of bionic eye implants have emerged as a promising approach to sight restoration. In just the past year, bionic vision prosthetics have progressed from proving their efficacy in clinical trials to becoming a commercial reality. As of early 2017, the prosthetic eye is already providing life-changing sight to nearly 900 severely vision-impaired patients around the world." Read the article here!
