Provided herein is a probe for treating an eye of a patient. In one or more embodiments, the probe includes a body, and a tubular element having a main lumen extending from the body, the tubular element comprising a distal end. The probe further includes a visualization optical fiber within the main lumen, the visualization optical fiber adapted to emit an illumination provided by at least one of a plurality of light sources connected to the visualization optical fiber. In some embodiments, the probe further includes an optical switching system (e.g., a time-division multiplexor) operable with the plurality of light sources, wherein the optical switching system is adapted to independently control each of the plurality of light sources. By providing time-division multiplexing between different surgical light sources, quasi-simultaneous illumination delivery through the same optical path may be achieved.

The present invention relates to a laser system for eye surgery with an eye-surgical laser apparatus and with a set of interface devices. The invention further relates to the laser apparatus itself, to the set of interface devices itself, to the use of the set and also to a method for laser-surgical eye treatment. The laser system for eye surgery comprises the eye-surgical laser apparatus having optical components for providing pulsed focused laser radiation with radiation properties matched to the generation of photodisruptions in human eye tissue and with a control unit for positional control of the radiation focus of the laser radiation, the control unit being designed for executing various control programs that represent various types of incision figure; and a set of interface devices, each of the interface devices including a contact body that is transparent to the laser radiation, with an abutment face for abutment against an eye to be treated, and also a coupling portion for detachable coupling of the interface device onto a counter-coupling portion of the laser apparatus, the interface devices of the set differing by virtue of a differing optical effect on the laser radiation provided in the laser apparatus.

Provided herein is a vitrectomy probe for treating an eye of a patient. In one or more embodiments, a vitrectomy probe may include a body, and a disruption element extending from the body, wherein the disruption element includes a needle having a main lumen and a port at a distal end thereof. The disruption element may further include an ultraviolet (UV) optical fiber projecting a UV laser beam for irradiating an area proximate the port. In some embodiments, a UV light source is optically connected with the UV optical fiber, the UV light source generating the UV laser beam in a spectral range of approximately 190-220 nanometers to target collagen fibers of a vitreous material entering the port.

An ophthalmological apparatus comprises a laser source for producing a pulsed laser beam, a scanner system for deflecting the pulsed laser beam at a treatment speed in the eye tissue along a scanning treatment line, a first scanning apparatus connected upstream of the scanner system for deflecting the pulsed laser beam and for producing a first scanning movement component superposed on the scanning treatment line in a first scanning direction at a first scanning speed that is higher as compared to the treatment speed, and a second scanning apparatus connected upstream of the scanner system for deflecting the pulsed laser beam and for producing a second scanning movement component, which is superposed on the first scanning movement component in a second scanning direction, which is at an angle to the first scanning direction, at a second scanning speed that is higher as compared to the first scanning speed.

Systems and methods for for driving the cutter of a vitrectomy handpiece using a substantially hermetically sealed system having a pneumatic pump for alternatively creating both positive pressure for pushing a first side of a diaphragm in the vitreous cutter and pulling negative pressure to pull the other side of the diagram, and vice versa.

Systems and methods for creating multi-spot laser light beams, multiplexing an illumination light and the multi-spot laser light beams, and delivering the multiplexed light to a surgical handpiece via a multi-core optical fiber cable.

A multi-beam splitter enables superimposing overlay content onto an optical field of view of a microscope using a compact and flexible design that is cost-effective for many applications. The multi-beam splitter also enables capturing of the optical field of view without the overlay content.

The invention relates to a modular Modular Laser Therapy Device (MLTD) to be used by ophthalmologists for eye surgery that integrates three most frequently used therapeutic devices into a single, compact unit enabling the treatment with capsulotomy, vitreolysis and iridotomy, with selective laser trabeculoplasty and with photocoagulation. While providing such modular laser device a method is provided for optomechanically coupling different ophthalmic modules into the single unit using two laser sources.

A vitreous disintegration device with multiple intake ports and a laser for vitreous disintegrating. The probe includes a needle to accommodate the ports for a more continuous and fluidic uptake of vitreous from an eye of a patient. Additionally, the use of a laser may be employed to disintegrate the vitreous in a manner that avoids blocking of ports and thus, further promoting the fluidic uptake. The laser may reach the ports at the channel at substantially the same time or in succussion. Further, the use of a laser for the disintegrating means that cutter vibrations may be reduced.

An ophthalmological apparatus comprises a laser source for producing a pulsed laser beam, a scanner system for deflecting the pulsed laser beam at a treatment speed in the eye tissue along a scanning treatment line, a first scanning apparatus connected upstream of the scanner system for deflecting the pulsed laser beam and for producing a first scanning movement component superposed on the scanning treatment line in a first scanning direction at a first scanning speed that is higher as compared to the treatment speed, and a second scanning apparatus connected upstream of the scanner system for deflecting the pulsed laser beam and for producing a second scanning movement component, which is superposed on the first scanning movement component in a second scanning direction, which is at an angle to the first scanning direction, at a second scanning speed that is higher as compared to the first scanning speed.
