A method for performing intrastromal photorefractive keratectomy in the cornea of an eye, using a pulsed, laser beam to photodisrupt a portion of the cornea, includes the initial step of focusing the beam to a focal spot at a selected starting point in the stroma. The starting point is located at a predetermined distance behind the epithelium of the cornea. While focused on the starting point, the laser beam is pulsed to disrupt a volume of the stroma which is approximately equal to the volume of the focal point. Subsequently, the beam is focused in a pa...
[ What is claimed is:] [1.] A method for modifying the curvature of the cornea of an eye, the eye including a stroma and an optical axis, the cornea including an anterior surface, the method comprising the steps of:focusing a laser beam through the anterior surface of the cornea to a plurality of focal spots in the stroma;pulsing the laser beam to modify a plurality of substantially contiguous volumes of stromal tissue at the plurality of focal spots to create a first cavity layer; andrepeating the focusing step and the pulsing step to create a plurality...
