Abstract:
A method and device for flapless, intrastromal keratomileusis for the correction of myopia, hyperopia and astigmatism, i.e., for vision correction by corneal reshaping without creating a flap. Ultra-short laser pulses are used to create a temporary micro-channel extending to an end point located within the cornea. A second series of ultra-short laser pulses are then delivered to photo-ablate material in the vicinity of the micro-channel end-point. The photo-ablated material may exit through the micro-channel used to deliver the laser pulses, or via a separate micro-channel. With the micro-channel oriented substantially normal to the optical axis of the cornea, and by continuing to supply the ultra-short laser pulses in the appropriate number while moving the point of ablation along the micro-channel, the photo-ablation of the intrastromal tissue may continue in a controlled fashion and the cornea reshaped in a predetermined manner without creating a flap.
