A method and system perform an ophthalmic procedure on an eye having an optical path from the lens to the retina. An image of at least part of the eye is received in a data processing unit. The image includes the optical path. The data processing unit determines keep out zone(s) and identifies undesirable feature(s) based on the image. The keep out zone(s) include the retina. The data processing unit also selects one of the undesirable feature(s) for removal. At least part of the undesirable feature is outside of the keep out zone(s). Confirmation for removal of the undesirable feature is received in the data processing unit. In response to receiving the confirmation, a control unit controls a laser to perform laser removal the at least the portion of the undesirable feature without targeting any portion of the keep out zone(s).

The invention relates to a device for measuring an optical penetration that is triggered in a tissue underneath the tissue surface by means of therapeutic laser radiation which a laser-surgical device concentrates in a treatment focus located in said tissue. The inventive device is provided with a detection beam path comprising a lens system which couples radiation emanating from the tissue underneath the tissue surface into the detection beam path. A detector device generating a detection signal which indicates the spatial dimension and/or position of the optical penetration in the tissue is arranged downstream of the detection beam path.

A laser instrument for therapy on the human eye, designed for surgery of the cornea, the sclera, the vitreous body or the crystalline lens, especially suitable for use in immediate succession with other instruments for eye diagnosis or eye therapy, in such a way that during the alternating use of the various instruments, the eye or at least the patient preferably remains in a predetermined position and alignment within one and the same treatment area.

Certain embodiments provide a cover mounted on top of a manifold, the cover comprising an exhaust opening and an inner surface forming a space between the inner surface of the cover and an outer surface of the manifold, wherein the space is configured to receive pressurized gas at an inlet positioned on a first side of a valve. The valve is coupled to the outer surface of the manifold and positioned within the space. The exhaust opening is positioned on a second side of the valve opposite the first side of the valve such that pressurized gas circulates from the inlet around the valve and exits through the exhaust opening.

An optical system for a laser therapy instrument for the application of laser radiation on and in the eye, includes a femtosecond laser, an objective. The objective or at least one lens or lens group of the objective is shiftable in the direction of the optical axis being intended for shifting of the focus position from the region of the cornea to the region of the crystalline lens and vice versa. The optical system may include at least two optical assemblies designed for the axial variation of the focus of the therapeutic laser radiation, with the focus variation range Δz differing between the individual assemblies and a changing device, designed for the insertion of any one of these assemblies into the therapeutic laser beam path at a time.

The present disclosure relates generally to illumination devices, systems, and methods for ophthalmic surgical procedures. Certain aspects of the present disclosure provide an illumination system which monitors and determines the amount of light delivered to a tissue within the ocular space, based upon data received from an imaging system. In certain aspects, if the amount of light delivered to the tissue is determined to be excessive, the illumination system may modify at least one parameter associated with the delivered light to reduce and/or eliminate phototoxic effects thereof. In certain aspects, if the amount of light delivered to the tissue is determined to be excessive, the illumination system may alert a surgeon, who may then trigger modification of the at least one parameter associated with the delivered light to reduce and/or eliminate phototoxic effects thereof.

An ophthalmic surgical cutting apparatus for cutting biological material including a handle, an outer tube attached to the handle and having a closed tip, a port formed in a side wall of the outer tube with a cusp formed by two or more intersecting surfaces, and an inner tube slidable within the outer tube and having a longitudinal axis and an open tip. The inner tube is in fluid communication with the handle, and the cusp of the port and the open tip interface during a cutting motion to fracture and cut biological materials and direct cut materials radially inward into the port.

A system for treating a media opacity in a vitreous media of an eye includes a visualization module adapted to provide visualization data of a portion of the eye via one or more viewing beams. The system includes a laser module adapted to selectively generate a treatment beam directed towards the media opacity in order to disrupt the media opacity. The laser module and the visualization module have a shared aperture for guiding the treatment beam and the one or more viewing beams towards the eye, the shared aperture being centered about a central axis. A controller is configured to acquire one or more defining parameters of the media opacity and determine when the media opacity is with a predefined target zone of a real-time viewing window. The media opacity is treated with the treatment beam when the media opacity is within the predefined target zone.

A surgical imaging system can include at least one light source, configured to generate a light beam; a beam guidance system, configured to guide the light beam from the light source; a beam scanner, configured to receive the light from the beam guidance system, and to generate a scanned light beam; a beam coupler, configured to redirect the scanned light beam; and a wide field of view (WFOV) lens, configured to guide the redirected scanned light beam into a target region of a procedure eye; wherein the beam coupler is movably positioned relative to the procedure eye such that the beam coupler is selectively movable to change at least one of an incidence angle of the redirected scanned light beam into the procedure eye and the target region of the procedure eye.

A laser eye surgery system used to treat vitreous bodies includes a laser source, a ranging subsystem, an integrated optical subsystem, and a patient interface assembly. The laser source produces a treatment beam that includes a plurality of laser pulses. The ranging subsystem produces a source beam used to locate one or more structures of an eye. In some embodiments, the ranging subsystem includes an optical coherence tomography (OCT) pickoff assembly that includes a first optical wedge and a second optical wedge separated from the first optical wedge. The OCT pickoff assembly is configured to divide an OCT source beam into a sample beam and a reference beam. The integrated optical subsystem is used to scan the treatment beam and the sample beam. In other embodiments, Purkinje imaging, Scheimpflug imaging, confocal or nonlinear optical microscopy, ultrasound, stereo imaging, fluorescence imaging, or other medical imaging technique may be used.
