Iris transplant helps boy see color

A boy born with a rare disease is now seeing the world in color for the first time. Seven-year-old Nathaniel Brantley was born without irises.

Without an iris, the eye lets in too much light. Thanks to new surgery, the first of its kind for a child and only the fourth ever performed in the US.

Nathaniel says he sees like a superhero.

Doctors at the Cincinnati Eye Institute inserted an iris implant and within 24 hours Nathaniel could see color.
