Artificial iris implant surgery was first performed by United States Pioneer Dr. Rosenthal and Dr. Rush from Germany in Since then, it has been operated on patients in Europe, Canada, Asia and the USA.
Iris determines each person's eye color. It is the eye's pigmented part with a hereditary nature. Its color is usually brown, black, blue, gray or green, which generally depends on two types of pigments: melanin and lipofuscin (for some types of green). In the absence of any pigment which is called albinism, eye color can change into the color of its flowing blood.
