  • Patent number: 9615971
    Abstract: An ophthalmic laser surgery apparatus for treating an eye of a patient includes: a laser light source configured to emit the pulse laser light; an objective lens configured to condense the pulse laser light emitted from the laser light source on the tissue to cause a photodistuption of the tissue; a scanner configured to scan a condensing position of the pulse laser light condensed by the objective lens; and a controller configured to control the scanner to adjust speed of scanning the condensing position depending on a size of the photodisruption which fluctuates in according to an aberration which fluctuates according to a change in the condensing position.

  • Publication number: 20120310224
    Abstract: An ophthalmic laser surgery apparatus for cutting a tissue in a cornea with laser light into a lenticular tissue corresponding to an amount of correction of refractive-error, includes: a pulse laser light source for outputting pulse laser light; an irradiation optical system including a moving optical system for moving a laser spot to which laser light is collected; a setting unit configured to set a cutting line for cutting the lenticular tissue to have a cut tissue by laser light irradiation such that the further cut lenticular tissue has a width equal to or less than a half of a diameter of the lenticular tissue, and that the further cut lenticular tissue is interlinked together without being separated from one another; and a control unit configured to drive the moving optical system based on the set cutting line and to cut a corneal tissue with laser light.
