The Stroma procedure uses laser surgery to change brown eyes to blue by removing the layer of melanin above the iris. It takes 20 seconds and occurs gradually over two to four weeks. It’s still in testing and not approved for widespread use. Eye color can also be changed with iris implants, and some people experience a natural change in eye color as they age.
Scientist Greg Homer invented a process known as the Stroma procedure to make it possible to change eye color through laser surgery. The technology only works in changing brown eyes to blue. A laser is used to remove the thin layer of brown pigmented tissue, known as melanin, above the iris of the eye to reveal the blue pigment that all humans naturally have. The laser procedure is estimated to take about 20 seconds, but the removal of the melanin occurs gradually over two to four weeks. The intervention was still in the testing phase and had not received approval for widespread use as of late 2013.
