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 system includes: a first movable stage which is movable with respect to an eye of a subject; a second movable stage mounted on the first movable stage, wherein the second movable stage is movable with respect to the first movable stage; a fixation target disposed on the second movable stage; and an optical system disposed in an optical path between the fixation target and the eye, wherein the optical system is configured for projecting the fixation target upon the eye to accommodate the eye, and wherein moving the second movable stage to a position where the fixation target is moved away from the eye by an additional amount causes blur cues of the fixation target to indicate to the subject that the fixation target is moving away from the eye while the size of an image of the fixation target on the retina of the eye decreases.

Abstract: A laser eye surgery system that has a patient interface between the eye and the laser system relying on suction to hold the interface to the eye. The patient interface may be a liquid-filled interface, with liquid used as a transmission medium for the laser. During a laser procedure various inputs are monitored to detect a leak. The inputs may include a video feed of the eye looking for air bubbles in the liquid medium, the force sensors on the patient interface that detect patient movement, and vacuum sensors directly sensing the level of suction between the patient interface and the eye. The method may include combining three monitoring activities with a Bayesian algorithm that computes the probabilities of an imminent vacuum loss event.

Abstract: A laser surgical method for performing a corneal incision while maintaining iris exposure below a predetermined exposure limit includes determining an initial iris exposure based on an initial treatment scan, determining whether the initial iris exposure is less than the predetermined exposure limit, generating a revised treatment scan comprising one or more treatment scan modifying elements when the initial iris exposure is greater than the predetermined exposure limit, and scanning the focal zone of a pulsed laser beam according to the revised treatment scan, thereby performing the corneal incision, wherein the one or more treatment scan modifying elements causes the iris exposure to be smaller than the predetermined exposure limit.

Abstract: Apparatus to treat an eye with an ophthalmic laser system comprises a patient interface having an annular retention structure to couple to an anterior surface of the eye. The retention structure is coupled to a suction line to couple the retention structure to the eye with suction. Liquid is added above the eye to act as a transmissive medium. A coupling sensor is coupled to the suction line to determine coupling of the retention structure to the eye. A separate pressure monitoring circuit having a much smaller volume than the suction line is connected to the annular retention structure to measure suction pressure therein. A system processor coupled to the monitoring pressure sensor includes instructions to interrupt firing of a laser when the pressure measured with a monitoring pressure sensor rises above a threshold amount.

Abstract: A laser system calibration method and system are provided. In some methods, a calibration plate may be used to calibrate a video camera of the laser system. The video camera pixel locations may be mapped to the physical space. A xy-scan device of the laser system may be calibrated by defining control parameters for actuating components of the xy-scan device to scan a beam to a series of locations. Optionally, the beam may be scanned to a series of locations on a fluorescent plate. The video camera may be used to capture reflected light from the fluorescent plate. The xy-scan device may then be calibrated by mapping the xy-scan device control parameters to physical locations. A desired z-depth focus may be determined by defining control parameters for focusing a beam to different depths. The video camera or a confocal detector may be used to detect the scanned depths.

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.

Abstract: A patient interface device for an ophthalmic surgical laser system includes a lens cone component for coupling to the laser system and a suction ring component for coupling to the patient’s eye. The suction ring includes a gripper with an opening for receiving and retaining the lens cone, and a flexible skirt joined to the gripper for coupling to the eye with a vacuum force. The flexible skirt includes a circular inner edge and a circular outer edge for contacting the eye surface, and a plurality of circumferentially distributed scleral support protrusions protruding from a circumferential side wall. The end surface of the scleral support protrusions are sloped in a side cross-sectional view. The scleral support protrusions have a length to width ratio from 1.1 to 2.1, and an arc-angle ratio of the scleral support protrusions to the gaps between them is from 2.2 to 3.0. The scleral support protrusions contact the surface of the eye when the skirt is docked to the eye, which minimize intraocular pressure increase due to docking and applanation while still achieving a good vacuum seal between the suction ring and the eye. The scleral support protrusions function to prevent major deformation of the sclera when the cornea is applanated.
