Abstract
A corneal implant adapted for implantation between layers of a cornea to focus an image on a retina of an eye includes an inlay, an outer perimeter, and a clear central region capable of refracting light to compensate for a refractive error of an eye. The inlay also has an annular opaque region comprising a plurality of holes or otherwise being adapted to transport nutrients. The annular opaque region extends from the outer circumference of the inlay to the clear central portion. The opaque region extends over a minority of the surface area of the implant. The anterior and posterior surfaces of the inlay are configured to abut adjacent layers of the cornea.
