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.

Abstract: A ophthalmic laser-assisted corneal lenticule extraction procedure that uses wavefront measurements to guide the formation of the corneal lenticule. The wavefront map measured from a free eye using a wavefront aberrometer is registered to the cornea of a docked eye based on comparisons of iris images and corneal markings. The docked-eye cornea-registered wavefront map is then corrected to be consistent with the Munnerlyn formula for the spherical power, and adjusted for any physician adjustments and/or myopia error due to a flat add in the lenticule, using Zernike polynomials. The corrected and adjusted wavefront map is then used to calculate the profiles of the bottom and top lenticule incisions in the applanated cornea, where higher-order components in the wavefront map are distributed to the bottom lenticule incision alone and lower-order components in the wavefront map are distributed to both the bottom and the top lenticule incision.

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 tangential to a parallel of latitude of the surface of the lenticule and then then moved 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, with the orientation of the scan line rotated between successive sweeps. To generate tissue bridge free incisions without leaving laser-induced marks in the eye, a laser pulse energy between 40 nJ to 70 nJ is used, and the sweeping speed is controlled such that the scan line step (the distance between the centers of consecutive scan lines) is between 1.7 μm and 2.3 μm.

Abstract: During laser ophthalmic procedures, back-reflected treatment laser light is detected by an auto-Z module and analyzed in real-time to determine various aspects of laser-tissue interaction during the procedure. This method can detect the presence of “black spots” (locations where no laser-tissue interaction occurred), sub-optimal incision quality, etc. in real time, and allows for dynamical adjustment of the laser treatment parameters such as pulse energy, laser spot separation, etc. to correct the detected problems. The auto-Z signal analysis may also depend on which incision segment or region is currently being cut, to optimally control different cutting segments. This method improves corneal incision quality and helps to achieves consistent laser-tissue interaction from patient to patient.

Abstract: A compact system for performing laser ophthalmic surgery is disclosed. An embodiment of the system includes a mode-locked fiber oscillator-based ultra-short pulsed laser capable of producing laser pulses in the range of 1 nJ to 5 μJ at a pulse repetition rate of between 5 MHz and 25 MHz, a resonant optical scanner oscillating at a frequency of 200 Hz and 21000 Hz, a scan-line rotator, a movable XY-scan device, a z-scan device, and a controller configured to coordinate with the other components of the system to produce one or more desired incision patterns. The system also includes compact visualization optics for in-process monitoring using a beam-splitter inside the cone of a patient interface used to fixate the patient's eye during surgery. The system can be configured such that eye surgery is performed while the patient is either sitting upright, or lying on his or her back.

Abstract: A corneal lenticule extraction procedure provides convenient re-treatment options when treatment interruptions occur. The procedure is executed by an ophthalmic laser system according to a programmed treatment plan, which defines an entry cut, an optional ring cut, a bottom lenticule incision having an optical zone, and a flat top bed incision. If an interruption occurs during the entry cut, the treatment plan is re-aligned with the partially formed entry cut and continued, or with a new entry cut placed at a different angular position. If an interruption occurs during the ring cut, the treatment plan is revised to define a larger ring cut concentric with the partially formed ring cut. If an interruption occurs during the bottom or top incision, the depth of the partially formed bottom or top incision is measured, and the treatment plan is revised to form a deeper bottom incision or a shallower top incision, respectively.

Abstract: A method used in a corneal lenticule procedure for finding the visual axis location before eye docking, to track the visual axis location displacement during docking, and to center the lenticule incision pattern at the visual axis location after docking, without ink-marking the visual axis location at the center of the cornea with ink or other substance. Two docking illumination beams are illuminated on the eye surface at oblique angles, and a first eye image is taken before docking while the eye looks at the fixation light of the laser system. A second eye image is taken after docking. The pre-docking cornea apex position is obtained based on the two reflected light spots of the docking illumination light. Pupil center is obtained in both images. The post-docking corneal apex is then calculated from the pre-docking cornea apex position and the pre- and post-docking pupil center positions.

Abstract: A method implemented in an ophthalmic surgical laser system that employs a resonant scanner, scan line rotator, and XY- and Z-scanners, for forming a corneal flap in a patient's eye with improved bubble management during each step of the flap creation process. A pocket cut is formed first below bed level, followed by the bed connected to the pocket cut, then by a side cut extending from the bed to the anterior corneal surface. The pocket cut includes a pocket region located below the bed level and a ramp region connecting the pocket region to the bed. The bed is formed by a hinge cut and a first ring cut at lower laser energies, followed by a bed cut and then a second ring cut, which ensures that any location in the flap bed is cut twice to minimize tissue adhesion. The side cut is formed by multiple side-cut layers at different depths which are joined together. All cuts are formed by scanning a laser scan line generated by the resonant scanner.

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.
