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 apparatus and a method to adjust mechanical properties of an intraocular lens including at least two haptics and at least one optical element, with the apparatus including at least one laser light source adapted to provide inscription of a pattern in the lens and a digital control unit adapted to control the laser light.

The invention relates to a device (1) for cutting human or animal tissue, such as a cornea (3), or a crystalline lens, said device comprising a femtosecond laser (2) that can emit a L.A.S.E.R. beam (4) in the form of impulses, and means for directing and focusing said beam onto or into the tissue for the cutting thereof as such. According to the invention, the device comprises means (9) for shaping the L.A.S.E.R. beam (4), which are positioned in the trajectory of said beam, and can modulate the energy distribution of the L.A.S.E.R. beam (4) in the focal plane thereof, corresponding to the cutting plane.

A laser cutting device for transparent material (23), which device is designed to focus the laser light (2) into a plurality of predetermined spots within the material (23), wherein the spots lie on a predetermined cutting line or cutting area (24) running substantially perpendicularly to the direction of incidence of the laser light (2), wherein the device comprises means for mode conversion (3) into laser light having a helical phase front (5), which means can be brought into and out of the beam path of the laser light (2).

An apparatus for laser-assisted eye treatment comprises a laser device and first and second accessory modules. The laser device is configured to provide focused laser radiation and has a coupling port. The first accessory module may form a patient interface and has a contact surface for an eye. The second accessory module includes a measuring device that performs measurements of the laser radiation. In certain embodiments, the measurements include the measurement of a pulse duration of the laser radiation using a detector operating on the basis of two-photon absorption. The first and second accessory modules are configured to detachably couple to the laser device at the coupling port. Only one accessory module can be coupled to the coupling port at a time. Therefore, the first accessory module must be removed from the coupling port before the second accessory module can be attached to the coupling port.

A planning device for a scanning pattern of a closed structure in an eye, an ophthalmic laser treatment device and corresponding methods including a scanning pattern of a closed structure in a tissue of a patient's eye in a single-pass method for the control of an ophthalmic laser treatment device, in which a starting point of the macroscopic scanning pattern which contains the scanning pattern is arranged in a region in which the angle between a direction of progress of the macroscopic scanning pattern and a direction of a maximum offset caused by movements of the eye relative to the ophthalmic laser treatment device is minimal, or in a region of a minimum change in the macroscopic scanning pattern (n the z-direction per unit of time, or in a region in which a direction of progress of the macroscopic scanning pattern is parallel to a direction of maximum offset.

A surgical system includes a laser source to generate a first set of laser pulses; a guiding optic to guide the first set of laser pulses to a target region; a laser controller to generate an electronic representation of a target scan pattern, and to control the guiding optic to scan the first set of laser pulses according to a portion of the target scan pattern to create a first photo-disrupted region in the target region; and a OCT imaging system to generate an image of a portion of the first photo-disrupted region. The laser controller can generate an electronic representation of a modified scan pattern in relation to the image generated by the SS-OCT imaging system, and control the guiding optic to scan a second set of laser pulses according the modified scan pattern.

An optical interface device having an opening for an optical path that can be non-circular and having engagement members having gradually varying angles of engagement. An embodiment of the interface device can be a one size fits all device, providing a configuration that fits in all typical eye openings, including narrow palpebral fissures and small eyes, while providing optical path access to features and structures of the eye. An embodiment of the interface device engages the limbus, cornea and sclera.

In order to take advantage of the real time nature of intra-operative refraction or wavefront aberrometry, and visually make the history of the measurements apparent to a surgeon, a histogram of frequency vs IOL results calculated from an IOL formula is computed and IOL suggestions being accumulated are displayed in a histogram. One embodiment is a means to present to a surgeon a histogram of intra-operative refractions. Another embodiment is to automatically and intra-operatively detect the aphakic phase of a cataract surgery to display a histogram of a recommended IOL power.

Cataract surgery is in recent years more and more augmented and supported by the application of laser cuts in the eye tissue. Such laser systems are separate units from the phacoemulsification system units that are usually used for cataract extraction. The laser systems require the patient to be positioned under the laser unit and then being moved under the surgical microscope next to the phacoemulsification unit. The here described invention relates to systems combining several aspects of the laser system and the phacoemulsification system. In particular, this invention relates to combining at least some parts of the control system and the housing for both systems and thereby minimizing and optimizing setup time, operating room footprint, patient flow and cost. Furthermore the here disclosed invention relates to integrating the laser system under the surgical microscope and thereby significantly reducing the surgery setup and complexity.
