The invention relates to an artificial iris has the ability to change color, including artificial iris diaphragm and photochromic mask layer, wherein the artificial iris diaphragm is a transparent disc structure of central hole, and the artificial iris diaphragm are distributed on the hole; and the artificial iris diaphragm contains photochromic shading layer photochromic shading layer is a concentric ring structure, when exposed to light, the light shielding layer of the photochromic material will change and reduce the transparency of the photochromic shading layer with thickness of thin and thick edge central distribution pattern, so that the light shielding layer of the photochromic ability (i.e. shading ability) and increased gradually with the increase of distance from the center increases. The artificial iris of the invention can be used for treating the human eye of the eye trauma or pathological iris defect, plays the role of the natural iris, and can adjust the pupil and the light amount according to the illumination in the surrounding environment. With a fixed wire loop with artificial iris also solves the existing artificial iris to suture in the eye, the surgery is difficult problem.
