Abstract: System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.

Abstract: There is disclosed a new low-level laser therapy apparatus and method of treating tissue. The invention includes a laser system that uses laser diodes and/or alternatively light emitting diodes (LED's), or both, and a digital interface that gives the operator the ability to generate sine waves or scalar waves as opposed to the simple on/off square waves. The invention also enables the operator to modulate not only the frequency, but also other wave characteristics such as the amplitude and phase. In one aspect, the invention involves modulating the phase relationship between multiple waves by taking one channel or wave which is pulsed through the laser system and then running a second channel or wave in relationship to the first channel, thereby creating a phased relationship, which has been discovered to provide a therapeutic and quantum healing effect on tissue.

Abstract: A wavefront sensor is integrated with a surgical microscope for allowing a doctor to make repeated wavefront measurements of a patient's eye while the patient remains on an operating table in the surgical position. The device includes a wavefront sensor optically aligned with a surgical microscope such that their fields of view at least partially overlap. The inclusion of lightweight, compact diffractive optical components in the wavefront sensor allows the integrated device to be supported on a balancing mechanism above a patient's head during a surgical procedure. As a result, the need to reposition the device and/or the patient between measuring optical properties of the eye and performing surgical procedures on the eye is eliminated. Many surgical procedures may be improved or enhanced using the integrated device, including but not limited to cataract surgery, Conductive Keratoplasty, Lasik surgery, and corneal corrective surgery.

Abstract: A system and method for altering the configuration of a transparent material (e.g. the cornea of an eye) requires identifying local stress distribution patterns inside the material. These patterns are then used to define boundary (interface) surfaces between volumes within the material. In operation, a laser unit performs Laser Induced Optical Breakdown (LIOB) along selected boundary surfaces to disrupt stress distribution patterns between volumes of the material that are separated from each other by the boundary surface. This LIOB allows an externally applied force to thereby alter the configuration of the material.
