ABSTRACT:
The invention provides implants suitable for use as an artificial cornea, and methods for making and using such implants. Artificial corneas having features of the invention may be two-phase artificial corneas, or may be three phase artificial corneas. These artificial corneas have a flexible, optically clear central core and a hydrophilic, porous skirt, both of which are biocompatible and allow for tissue integration. A three-phase artificial cornea will further have an interface region between the core and skirt. The artificial corneas have a high degree of ocular tolerance, and allow for tissue integration into the skirt and for epithelial cell growth over the surface of the prosthesis. The use of biocompatible material avoids the risk of disease transmission inherent with corneal transplants, and acts to minimize post-operative inflammation and so to reduce the chance or severity of tissue necrosis following implantation of the synthetic cornea onto a host eye.
