Self-regulated artificial iris and method of fabricating the same

摘要

The present disclosure provides an artificial iris prepared by forming a ring-shaped hydrophilic region on a biocompatible substrate, coating a curable material thereon and then coating a photoreactive material mimicking the iris frills through optical irradiation. The artificial iris may be implemented into the real human eye and is capable of regulating the intensity of the light reaching the retina through the pupil depending on the intensity of ambient light.

主权项

1. A self-regulated artificial iris comprising:
a substrate on which a ring-shaped hydrophilic groove region is formed; a curable material layer which is coated on the ring-shaped hydrophilic groove region and is cured, the curable material layer comprising radial surface wrinkles in a direction perpendicular to circles concentric to and coplanar the ring-shaped hydrophilic groove region; and a photoreactive material layer coated on the curable material layer.
