Abstract: A method and apparatus for buckling contact lenses includes mounting a lens blank to be buckled on the contoured surface of a lens mounting tool so that the lens adopts a datum position, bringing a protruding element or elements into contact with the lens, such that the lens' contact point is coincident with the datum level, setting an indicator gauge to a setting to indicate the position of the contact point, moving the element or elements away from touch contact with the lens, setting a new elevation of the mounting tool by displacing the mounting tool over a distance commensurate with the predetermined degree of buckling of the lens required, and bringing the protruding element or elements into descending engagement with a portion of the lens, thereby buckling the lens to the shape of the contoured surface of the lens mount until the protruding elements have been displaced, the predetermined distance relative to the datum.

Abstract: A corneal lens has a substantially circular optical correction zone and one or more lugs extending therefrom for engagement with depressions on the sclera of the eyeball existing between the four ocular muscles attached thereto.
