Doctor uses tattoos to boost blind patients' confidence

Tattoos placed on the eyeball are opening up new possibilities for some eye injury patients.

One such procedure, which adds natural-looking color to an eye after injury, was performed live at the New York City Tattoo Convention in June by Dr. Emil Chynn, a surgeon, owner and medical director at Park Avenue Lasek in Manhattan. The goal is to match the tattooed eye with the look of a normal eye, and as a result, boost a patient's self-confidence.

Other surgeons aiming for a similar outcome usually just inject dye into the cornea using a needle and syringe, according to Chynn. While that may improve an eye's appearance, the result could just look like a big blotch of brown or black, for example, he said.

"So it's a very delicate procedure, and we're using the most fine tattoo needle as possible," Dr. Chynn said of his approach in an interview with CNBC.
