An exemplary surgical device includes a shaft with a lumen defined therethrough and an element movable from a stored position to a deployed position in which a larger portion of the element extends out of the distal end of the lumen; wherein motion from the stored position to the deployed position causes a first leg of the element to advance distally relative to the distal end of the shaft, and causes a second leg of the element to move proximally relative to the distal end of the shaft.

A method of treating a lens of a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form a treatment pattern of the light beam, delivering the treatment pattern to the lens of a patient's eye to create a plurality of cuts in the lens in the form of the treatment pattern to break the lens up into a plurality of pieces, and removing the lens pieces from the patient's eye. The lens pieces can then be mechanically removed. The light beam can be used to create larger segmenting cuts into the lens, as well as smaller softening cuts that soften the lens for easier removal.

The control unit executes an irradiation plan acquisition step and a spot interval guide display step. At the irradiation plan acquisition step, the control unit acquires an irradiation plan for irradiating a patient's eye with treatment laser light using a contact lens having a reflective surface that reflects the treatment laser light in a direction intersecting the optical axis. At the spot interval guide display step, the control unit controls the internal display unit to display a spot interval guide indicative of an appropriate interval between a plurality of irradiation spots in accordance with the progress of the irradiation plan. The plurality of irradiation spots are scheduled to be irradiated with the laser light.

Particular embodiments include, by a computing device, receiving one or more wavefront elevation maps for a patient's eye and identifying one or more attributes of the one or more wavefront elevation maps corresponding to vitreous floaters. The one or more attributes may include localized spatial variation of the one or more wavefront elevation maps; temporal variation among a plurality of wavefront elevation maps; and depth information indicating scattering of light from within the vitreous of the patient's eye. A machine learning model may be trained and utilized to characterize vitreous floaters based on the one or more wavefront elevation maps and other patient data. The wavefront elevation maps may be measured using an aberrometer. The aberrometer may be integrated with a LIDAR system to estimate depth of scattered light. A common laser light source may be used for both the aberrometer and the LIDAR system.

Systems and methods are described for a combined Femto and Phaco surgical system built into a single housing. The system advantageously permits each of the Femto device and Phaco surgical tray to be rotated out of the way or into the position without requiring movement of a patient. Thus, a user can switch between Femto and Phaco surgical procedures without movement of the patient.

A system and method of treating target tissue in a patient's eye, which includes generating a light beam, deflecting the light beam using a scanner to form first and second treatment patterns, delivering the first treatment pattern to the target tissue to form an incision that provides access to an eye chamber of the patient's eye, and delivering the second treatment pattern to the target tissue to form a relaxation incision along or near limbus tissue or along corneal tissue anterior to the limbus tissue of the patient's eye to reduce astigmatism thereof.

Certain embodiments provide a vacuum generation system with an override PID controller, a proportional valve, and a vacuum generator. The override PID controller allows the vacuum generation system to control the operating range of supply air pressure that is provided to the vacuum generator. By controlling the operating range of the supply air pressure, the vacuum generation system is able to avoid entering the decreasing or non-monotonic region of the vacuum generator.

A method for altering an eye color of a patient with a color alteration procedure is disclosed that may include imaging the iris with an image sensor prior to the color alteration procedure to generate an image of the iris. A mapping of the iris may be generated from the image. The mapping may include a number of regions corresponding to varying absorption coefficients of a treatment wavelength in the stromal pigment of the iris. A laser system may be set, based on the mapping, to deliver laser light at a laser power sufficient to cause elimination of at least a portion of stromal pigment in the iris. The laser light may then be delivered with the laser system.

Devices and methods are disclosed for improved followability in laser-based ocular procedures. In some embodiments, an ophthalmic instrument comprises a projection located at the distal end of the shaft or cannula, the projection having a distal surface in proximity to the distal end of the optical fiber, the distal surface adapted to be positioned facing the treatment area during use of the ophthalmic instrument. An example method includes delivering laser energy through an optical fiber to the treatment area, wherein the distal surface of the projection inhibits bubbles formed during the procedure from moving distally away from the distal end of the ophthalmic instrument.

An ophthalmic surgical system for monitoring incision performance includes a laser device, a camera, and a computer. laser device delivers a laser beam with a laser setting energy towards a target to create optical breakdowns in the target. The camera generates images of the optical breakdowns in the target. The computer instructs the laser device to create the optical breakdowns in the target to yield a test pattern. The test pattern comprises regions of optical breakdowns, where each region was created with a different laser setting energy. From the images, the computer identifies a lowest energy region with substantially continuous optical breakdowns, and designates the laser setting energy used to create the identified region as a threshold energy.
