  • Patent number: 10690486
    Abstract: A measurement apparatus for measuring a laser focus spot size, which includes a two-dimensional image detector and an imaging system which forms a magnified image of a focus spot located an object plane onto the image detector. The imaging system includes at least an objective lens. A sealed liquid container is secured over a part of the objective lens such as the optical surface of the objective lens is immersed in the liquid (e.g. water) within the container. The liquid container has a window through which the laser beam enters. An image processing method is also disclosed which processes the image obtained by the image detector to obtain the focus spot size while implementing an algorithm that corrects for the effect of ambient vibration.

  • Publication number: 20200192730
    Abstract: Systems, methods, and computer-readable media are described for interoperability between programs associated with different addressing modes. A caller program associated with a first addressing mode (e.g., a 32-bit program or a 64-bit program) that is executing within a parent runtime environment makes a call to an external interface to execute a target callee program that is associated with a second addressing mode different from the first addressing mode. The target callee program is then executed in a pre-initialized secondary runtime environment that executes on the same task or thread as the parent runtime environment.

  • Patent number: 10610411
    Abstract: Systems and methods for adjusting an angle of incidence of a laser surgery system include a laser source to produce a laser beam and an optical delivery system to output the laser beam pulses to an object at an adjustable incident angle. A first rotator assembly receives the beam from the laser source along a first beam axis. The first rotator assembly rotates around the first beam axis and the first rotator assembly outputs the beam along a second beam axis different from the first beam axis. A second rotator assembly receives the beam from the first rotator assembly along the second beam axis. The second rotator assembly rotates around the second beam axis. The second rotator assembly follows the rotation of the first rotator assembly and the first rotator assembly is independent of the rotation of the second rotator assembly.

  • Publication number: 20200069470
    Abstract: An ophthalmic laser procedure for forming a lenticule in a cornea and extracting the lenticule from the cornea to accomplish vision correction. An ophthalmic laser system is used to form top and bottom lenticule incisions defining a lenticule in between, and further to form top and/or bottom entry cuts that respectively end unambiguously near the top or bottom lenticule surface. The bottom entry cut intersects both the top and bottom lenticule incisions but ends near the bottom lenticule incision. The entry cuts allow the surgeon to insert a surgical tool which reaches the intended top or bottom lenticule surface without ambiguity. The lenticule has an optical zone in the center that defines the optical power of the lenticule, and a transition zone in the periphery, where the end points of the entry cuts are located in the transition zone.

  • Publication number: 20200064622
    Abstract: An ophthalmic laser system uses a non-confocal configuration to determine a laser beam focus position relative to the patient interface (PI) surface. The system includes a light intensity detector with no confocal lens or pinhole between the detector and the objective lens. When the objective focuses the light to a target focus point inside the PI lens at a particular offset from its distal surface, the light signal at the detector peaks. The offset value is determined by fixed system parameters, and can also be empirically determined by directly measuring the PI lens surface by observing the effect of plasma formation at the glass surface. During ophthalmic procedures, the laser focus is first scanned insider the PI lens, and the target focus point location is determined from the peak of the detector signal. The known offset value is then added to obtain the location of the PI lens surface.

  • Publication number: 20200046558
    Abstract: An ophthalmic surgical laser system and method for forming a lenticule in a subject's eye using “fast-scan-slow-sweep” scanning scheme. A high frequency scanner forms a fast scan line, which is placed by the XY and Z scanners at a location tangential to a parallel of latitude of the surface of the lenticule. The XY and Z scanners then move the scan line in a slow sweep trajectory along a meridian of longitude of the surface of the lenticule in one sweep. Multiple sweeps are performed along different meridians to form the entire lenticule surface, and a prism is used to change the orientation of the scan line of the high frequency scanner between successive sweeps. In each sweep, the sweeping speed along the meridian is variable, being the slowest at the edge of the lenticule and the fastest near the apex.

  • Publication number: 20200042331
    Abstract: Aspects of the present disclosure are directed to methods, systems, and computer program products for using dynamic-link library based on memory size. In the method, a request for calling a first function in a Dynamic-link library (DLL) at runtime is received first. A size of a memory allocated to the DLL is then determined. Then call relationship of functions in the DLL is obtained. At last, functions related to the first function in the DLL are loaded into the memory allocated to the DLL based on the size of the memory allocated to the DLL and call relationship of functions in the DLL.

  • Publication number: 20190350756
    Abstract: Some embodiments disclosed here provide for a method fragmenting a cataractous lens of a patient's eye using an ultra-short pulsed laser. The method can include determining, within a lens of a patient's eye, a high NA zone where a cone angle of a laser beam with a high numerical aperture is not shadowed by the iris, and a low NA zone radially closer to the iris where the cone angle of the laser beam with a low numerical aperture is not shadowed by the iris. Laser lens fragmentation is accomplished by delivering the laser beam with the high numerical aperture to the high NA zone, and the laser beam with the low numerical aperture to the low NA zone. This can result in a more effective fragmentation of a nucleus of the lens without exposing the retina to radiation above safety standards.
