ABSTRACT:
A technique relating to orthokeratology for correcting presbyopic and hyperopic errors by means of a shallow-plane photo-microwelded intralamellar band. The technique is non-contact and is intended to be micro-invasive to allow its frequent repetition as a maintenance therapy. Non-contact photonic energy and a cyro-energy systems are provided in combination for creating an "inverse" thermal gradient in the anterior cornea. A computer-controlled spatial application system is provided for very high speed scanning of a photonic beam over the cornea. A "prosthetic" lens maintains the corneal surface in an optimal condition and prolate curvature. The lens-prosthesis further is adapted to mediate cryo- and photonic energies that propagate through the cornea to create the desired shallow-plane microweld effects.
