An artificial iris implantation is the insertion of a prosthetic iris to replace a damaged or congenitally defected iris. The iris is located at the front of the eye and controls the amount of light which reaches the retina by using muscles to contract and dilate the pupil. The pigmentation of the iris determines the color of the eye.
If the iris is damaged or defective, it can cause problems with vision by allowing too much light into the retina or by creating shadows and sensitivity to light.
Many iris implants are custom made and tailored to the patient, in order to match the other eye and are usually made of silicone. Once the iris implant replaces the damaged or defective iris, the patient should experience a relief of symptoms.
The procedure is not recommended for cosmetic purposes, as there is a risk of vision damage.
