VACUUM CONTROL FOR A VITRECTOMY PROBE
Vitrectomy probes and methods related thereto are disclosed herein. A vitrectomy probe may include a hand piece comprising a housing, a venturi, a piloted proportional valve disposed in the housing, and aspiration tubing fluidly coupled to the piloted proportional valve. In some embodiments, the piloted proportional valve and/or venturi may be disposed in the surgical console. The vitrectomy probe may further include a cutting mechanism attached to a distal end of the hand piece, wherein the cutting mechanism may be fluidly coupled to the aspiration tubing.
OPTHALMOLOGIC THERAPY SYSTEM AND METHOD FOR PROCESSING A PORTION OF A PROCESSING VOLUME OF A TRANSPARENT MATERIAL BY APPLICATION OF FOCUSED RADIATION
A system for processing a portion in a processing volume of a transparent material by application of focused radiation including a device for generating and an optical system for focusing radiation, with a device for changing the position of the focus of the radiation and a control device. This system performs a slow scanning movement of the focus and an independent fast scanning movement of the focus which section can be moved by the slow scanning movement in the entire processing volume in an arbitrary direction; as well as by a system into which a scan pattern is encoded, with scanning movement including at least one lateral base component in the x- and/or y-direction, which is superimposed by components with synchronous change-of-direction-movements in the z-direction and in x-direction and/or y-direction. The invention also includes corresponding methods, a control program product and a planning unit.
LASER INSTRUMENT FOR EYE THERAPY
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.
ILLUMINATED SURGICAL PROBE HAVING A VARIABLE ILLUMINATION NUMERICAL APERTURE
A surgical probe system comprising a surgical probe having a probe needle, an optical fiber incorporated onto the probe needle, wherein a proximal end of the optical fiber is connected to a light source and a distal end of the optical fiber projects illumination light from the light source over a tip of the probe needle; and an adjustment mechanism that varies the illumination light between a first beam having a first numerical aperture that facilitates vitreous visualization and a second beam having a second numerical aperture that facilitates background illumination, wherein the second numerical aperture is larger than the first numerical aperture.
SYSTEM AND METHOD FOR MONITORING PHOTOTOXICITY DURING OPHTHALMIC SURGERY
The present disclosure provides a system and method for monitoring phototoxicity caused by vitreous visualization device (VVD) illumination during ophthalmic surgery. The systems and methods determine the cumulative amount of optical energy incident on the retina, which corresponds to phototoxicity, the distance between a cutter of the VVD and the retina, and areas where the vitreous has been removed, or any combination thereof. The disclosure further provides a method for monitoring and preventing phototoxicity caused by VVD illumination during ophthalmic surgery. The method may further include determining the distance between a cutter of the VVD and the retina, and determining areas where the vitreous has been removed based on focus areas of the retina that the plurality of light spots has contacted.
OPHTHALMOLOGICAL LASER THERAPY DEVICE
An ophthalmological laser therapy device including a laser system, an x-y scanner, collecting optics and a z-scanner. The invention also relates to a method for processing a tissue of an eye by a therapeutic laser beam of an ophthalmological laser therapy device. The invention provides an ophthalmological laser therapy device and a corresponding method which permit, with minimal engineering complexity, a very quick positioning of the laser spot in a large volume region, in particular in a large x-y region perpendicular to the optical axis. The problem is also solved by a method for processing a tissue of the eye or a material located in an eye using an ophthalmological laser therapy device, wherein each sub-section of the tissue of the eye is processed using a corresponding positioning or the device for the adjustable redirecting of the laser beam in an image field of the collection optics.
