    摘要： Surgical cutting heads for use in infusion/aspiration devices for performing surgery on various parts of the body, are disclosed. These cutting heads include, a first tube, having a cutting edge formed in its proximal end and an inner space bounded by the interior surface of this tube. This first tube contains at least one asymmetrical two-sided notch for cutting tissue, which notch proceeds distally from the first tube's proximal end to an apex where the sides of the notch meet. A first side of the notch commences at the first tube's proximal end and is generally in a plane parallel to the first tube's longitudinal axis. The second side of the notch commences at the first tube's proximal end, at a point radially inwardly therefrom, and extends into the first tube's inner space. A second open tube is disposed concentrically around the first tube and has at least one projection located at its proximal end and extending radially inwardly therefrom overhanging the first tube's proximal end. The interior surface of the second tube is opposed to the exterior surface of the first tube, and the respective opposed surfaces of these tubes define a traversable inner space between the tubes.

    摘要： A laser beam ophthalmological surgery method includes the steps of generating a laser beam and splitting the generated laser beam into multiple laser beams which are simultaneously focused onto a plurality of scanners. Each scanner in turn produces a predetermined scanning pattern focused on the cornea of a patient's eye to ablate the cornea tissue and with at least two beams simultaneously scanning and ablating the cornea tissue. Scanning is controlled from a central processing unit to perform the surgical procedure, removing a laser thickness of the cornea tissue to provide a safer and more predictable surgical procedure in the reshaping of the cornea. A laser ophthalmological surgery apparatus is provided which includes a laser generating a laser beam, a beam splitter for splitting the laser beam into a plurality of laser beams, and a plurality of scanners, each positioned for receiving one of the laser beams from the beam splitter and producing a predetermined scanning pattern from the laser beam and impinging the scanning pattern upon the cornea of a patient's eye.

    摘要： The present invention provides a surgical technique and instrument kit that allows for subtle modification of the corneal curvature by interlamellar injection of a synthetic gel at the corneal periphery while sparing the optical zone. The gel viscosity, volume and disposition within the surgical annular track as well as the diameter of the track, width, depth, and location are all parameters in the refractive change obtained. Following ultrasonic pachymetry performed centrally and at a selected wound entrance located about 2.5 to 3.5 mm from the apex, a one millimeter or so wide, about 75-85% corneal thickness depth radial incision is performed with a micrometric diamond knife adjusted to about 86% corneal thickness. Inserted through the partial-depth incision, a corkscrew-like dissector or helicoidal spatula forms a 360.degree. annular track centered about the apex. A transparent gel is manually injected through the incision, filling the annular channel. Using a surgical keratometer mounted to an operation microscope, the final corneal power is adjusted by massaging and removing the gel as necessary during the primary procedure or subsequent procedures, as the GIAK technique is reversible.
