Abstract: A method for forming an incision in an eye, the method including performing a first pass of a first laser beam along a path within an eye, wherein after completion of the first pass there exists a residual uncut layer at an anterior surface of a cornea of the eye. The method further including performing a second pass of a second laser beam only along a portion of the path that contains the residual uncut layer, wherein after completion of the second pass, the residual uncut layer is transformed into a full complete through surface incision.

Abstract: A laser system that includes a laser source emitting a laser beam along an axis and a keratometer. The keratometer includes a first set of individual light sources that are equally spaced from one another along a first ring and that direct a first light toward an eye and a second set of individual light sources that are equally spaced from another along a second ring and direct a second light toward the eye, wherein the first ring and said second ring are co-planar and concentric with one another about the axis. The laser system includes a telecentric lens that receives the first light and second light reflected off of the eye and a detector that receives light from the telecentric lens and forms an image. The laser system also includes a processor that receives signals from said detector representative of the image and determines an astigmatism axis of the eye based on the signals.

Abstract: A method that includes illuminating an eye with light at a first time and a second time and generating a first image of the eye based on the light that illuminates the eye at the first time. The method includes generating a second image of the eye based on the light that illuminates the eye at the second time. The method further includes positioning a laser source relative to the eye, wherein the laser source generates a therapeutic laser beam to be directed to the eye, wherein the first time is just prior to the therapeutic laser beam being directed to the eye and the second time is prior to the first time. The method further includes correcting orientation of the laser source relative to the eye based on a correlation function that is defined for the first and second images of the eye.

Abstract: A method of generating three dimensional shapes for a cornea and lens of an eye, the method including illuminating an eye with multiple sections of light and obtaining multiple sectional images of said eye based on said multiple sections of light. For each one of the obtained multiple sectional images, the following processes are performed: a) automatically identifying arcs, in two-dimensional space, corresponding to anterior and posterior corneal and lens surfaces of the eye by image analysis and curve fitting of the one of the obtained multiple sectional images; and b) determining an intersection of lines ray traced back from the identified arcs in two-dimensional space with a known position of a section of space containing the section of light that generated the one of the obtained multiple sectional images, wherein the determined intersection defines a three-dimensional arc curve. The method further including reconstructing three-dimensional shapes of the anterior and posterior cornea surfaces and the anterior and posterior lens surfaces based on fitting the three-dimensional arc curve to a three-dimensional shape.

Abstract: A system and apparatus for increasing the amplitude of accommodation and/or changing the refractive power and/or enabling the removal of the clear or cataractous lens material of a natural crystalline lens is provided. Generally, the system comprises a laser, optics for delivering the laser beam and a control system for delivering the laser beam to the lens in a particular pattern. There is further provided apparatus for determining the shape and position of the lens with respect to the laser. There is yet further provided a method and system for delivering a laser beam in the lens of the eye in a predetermined shot pattern.
