The University of Colorado Hospital has performed the state's first bionic eye transplant, allowing a woman to see her son for the first time in 15 years.
The Denver Post reports Jamie Carley suffers from retinitis pigmentosa, a disease that slowly kills retinal cells. The Johnstown woman was given a new vision system following five hours of surgery at the university hospital in November.
Doctors had placed a microchip in the retina of one eye. A pair of glasses equipped with a small camera transmits video to the microchip, stimulating her optic nerve.
The bionic eye does not give Carley perfect vision but allows her to make out shapes. She has begun the process of improving her vision by using her brain to interpret the new optical signals.
