  • Patent number: 6764439
    Abstract: A device is disclosed for ophthalmologic microsurgery for improving the drainage of the aqueous humor in the eye of a living being, wherein the device has an endoscope connected to a monitor screen and includes a tube-shaped probe adapted for insertion into an eye, and one or more channels co-axially disposed therein and provided with optical elements for focusing and transmitting images from the viewing field in the eye, and wherein the probe houses a surgical tool which is movable in axial direction and about the longitudinal axis so that by means of the oscillating and/or vibrating tool a passageway can be opened in the tissue of the trabecular meshwork for connecting the anterior chamber with the Schlemm's canal.
