A system for ophthalmic surgery on an eye includes: a pulsed laser which produces a treatment beam; an OCT imaging assembly capable of creating a continuous depth profile of the eye; an optical scanning system configured to position a focal zone of the treatment beam to a targeted location in three dimensions in one or more floaters in the posterior pole. The system also includes one or more controllers programmed to automatically scan tissues of the patient's eye with the imaging assembly; identify one or more boundaries of the one or more floaters based at least in part on the image data; iii. identify one or more treatment regions based upon the boundaries; and operate the optical scanning system with the pulsed laser to produce a treatment beam directed in a pattern based on the one or more treatment regions.

An imaging-based laser system can include a laser-beam system, configured to generate and scan a beam of laser pulses with an adjustable laser-power parameter to points of a scan-pattern in an eye, and an imaging-based laser-controller, configured to image a layer in the eye, to control the scanning of the beam of laser pulses to the points of the scan-pattern, and to control a laser-power parameter of the laser pulses according to the distance of the points of the scan-pattern from the imaged layer.

A method for cataract surgery on an eye of a patient includes scanning a first focus position of a first pulsed laser beam at a first pulse energy of between one-half microjoule and 50 microjoules in a first scanning pattern to photodisrupt a first tissue structure portion with a plurality of pulses of the first laser beam to form an incised surface; and afterwards, scanning a second focus position of a second pulsed laser beam having a second pulse energy being between 50 microjoules and 5,000 microjoules in a second scanning pattern that is co-registered to the first scanning pattern to further photodisrupt the same first tissue structure portion with the second laser beam to further separate segments of the first tissue structure along the incised surface.

Methods and systems for tracking a position and torsional orientation of a patient's eye. In one embodiment, the present invention provides methods and software for registering a first image of an eye with a second image of an eye. In another embodiment, the present invention provides methods and software for tracking a torsional movement of the eye. In a particular usage, the present invention tracks the torsional cyclorotation and translational movement of a patient's eye so as to improve the delivery of a laser energy to the patient's cornea.

A method includes, using a laser, thinning a target site in an iris of an eye by irradiating the target site with one or more first radiation-pulses. Subsequently to thinning the target site, a peak intensity of radiation beams emitted by the laser is increased and, subsequently to increasing the peak intensity, a hole is formed through the target site by, using the laser, irradiating the target site with one or more second radiation-pulses.

A method of treating glaucoma in an eye includes obtaining a surgical instrument having a cutting means and severing/cleaving an anterior attachment of a portion of trabecular meshwork of the eye proximate to Schwalbe's line with the cutting means while leaving the ciliary muscle tendons attached to the scleral spur of the portion of trabecular meshwork to create a trabecular meshwork leaflet. The surgical instrument including the cutting means is preferably a handheld microsurgical cutting instrument having at least one sharpened edge. Alternatively, the instrument may be an invasive or non-invasive laser cutting instrument with a laser cutting means; a vibratory cutting instrument with a vibratory cutting means; or a thermal cutting instrument with a thermal cutting means. The step of severing the portion of trabecular meshwork is preferably characterized by a linear cleavage plane severing the attachment portion without removing substantially any trabecular meshwork from the eye.

An ophthalmic assembly includes a frame, flange, and light emitter. The frame supports an optical lens. A first end of the flange is connected to the frame. A second end of the flange rests on a pars plana region of the sclera of a patient's eye. The light emitter is connected to the flange proximate the second end to direct light into a vitreous cavity of the patient's eye. This occurs through the sclera at the pars plana region and uniformly illuminates the vitreous. A transscleral illumination system includes the ophthalmic assembly and a processor in communication with the light emitter. A setting of the light emitter may be controllable via the processor, e.g., in response to a user input signal.

Systems and methods for performing laser operations on the structures of the eye, including the drain angle, trabecular mesh and the area of the eye where the iris and cornea meet. Laser systems and methods for treating glaucoma. Laser assisted MIGS procedures.

The invention relates to a planning device for generating control data for a treatment apparatus, which by means of a laser device generates at least one cut surface in the cornea, and to a treatment apparatus having such a planning device. The invention further relates to a method for generating control data for a treatment apparatus, which by means of a laser device generates at least one cut surface in the cornea, and to a corresponding method for eye surgery. The planning device is thereby provided with calculating means for defining the corneal incision surfaces, wherein the calculation means determines the corneal incisions such that after inserting an implant into the cornea, existing refractive errors are counteracted.

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.
