An implant (20) for reshaping a cornea (30) includes a peripheral supporting ring structure (22), a plurality of filaments (26), and an inlay (24).

The implant is surgically positioned with the inlay (24) generally directly over an ectatic region of the cornea (30) to provide direct re-contouring of the cornea (30). The inlay (24) can be provided with a predetermined optical curvature and/or optical prescription to further correct the patient's vision.
