The iris is an important part of the eye structure and is mainly used to adjust the amount of external light into the eye. When the external light is strong, the iris will shrink, reducing the damage of light to the eyes. In dimly lit conditions, the iris will zoom in, increasing the amount of light entering the eye and helping you see the object. Once the iris is damaged, the most common symptom of the patient is photophobia. The data show that patients with congenital aniridia are rare, and the incidence rate is 1:133931, while the acquired iris-free is mostly caused by trauma. In order to reduce the symptoms of photophobia, colored glasses and opaque contact lenses have been used in the past to alleviate the discomfort of patients with corneal damage, but these treatments have limited effectiveness. Later, scientists developed an iris-type intraocular lens. The implantation of the crystal into the patient can seriously solve the original symptoms of photophobia, tearing, dizziness, dizziness, nystagmus, etc., and effectively improve the patient's vision. However, this type of intraocular lens is not omnipotent. Because it is an external material for post-implantation, it does not have the neuromodulation function of its own iris, so it is impossible to adjust the size of the pupil according to the change of light intensity. Scientists say they will try to calibrate a suitable size, leaving a medium-sized pupil position to keep the light entering the eye at an appropriate level. Scientists at the University of Technology in Tampere, Finland, have developed a synthetic iris that can be adjusted for external light. It is worth noting that this synthetic iris does not require any external control equipment.
