An apparatus for adjusting the corneal curvature of the eye comprising a corneal implant having an elongated, hollow tubular shell which is implantable into the cornea in encircling relation to the central optic zone of the cornea. The implant has hinged portions along its the inner and outer arcs, and the corneal implant is filled with a predetermined amount of a biocompatible material in various forms such as rings or strands. The biocompatible material is strategically located within the flexible shell to alter its dimensions in thickness or diameter and thereby adjust the corneal curvature to correct refractive error.
