  • Varying a numerical aperture of a laser during lens fragmentation in cataract surgery
    Patent number: 10369054
    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.

  • SYSTEMS AND METHODS FOR HIGH SPEED MODULATION OF A RESONANT SCANNER IN OPHTHALMIC LASER APPLICATIONS
    Publication number: 20190110926
    Abstract: An ophthalmic surgical laser system includes: a laser that produces a pulsed laser beam having a pulse energy and pulse repetition rate; a high frequency fast scanner; an XY-scan device; a Z-scan device; and a controller. The controller controls the high frequency scanner to produce a scan line having a scan width; controls the XY-scan device and the Z-scan device to carry out of first sweep of the scan line in a first sweep direction and to carry out a second sweep of the scan line in a second sweep direction that is not parallel to the first sweep direction thereby defining an overlap region. At least one of the pulse energy, repetition rate, XY-scan speed, and the scan width is varied so as to accelerate the cutting speed and reduce the exposure of ophthalmic tissue in the overlap region to multiple exposures of laser pulses configured to modify ophthalmic tissue.

  • PATIENT INTERFACE DEVICE FOR OPHTHALMIC SURGICAL LASER SYSTEM
    Publication number: 20180303664
    Abstract: A single-piece patient interface device (PI) for coupling an patient's eye to an ophthalmic surgical laser system, which includes a rigid shell, a flexible suction ring joined to a lower edge of the shell, an applanation lens, and a flexible annular diaphragm which joins the applanation lens to the shell near the lower edge of the shell. The flexible diaphragm allows the applanation lens to move relative to the shell, including to shift in longitudinal and lateral directions of the shell and to tilt. In operation, the surgeon first secures the PI to the patient's eye by hand, and then couples the laser system to the PI by lowering the laser delivery head into the PI shell. During the lowering process, the laser delivery head presses the applanation lens down relative to the PI to applanate the cornea of the eye.
