ABSTRACT:
The invention provides a probe set for use particularly in the canaliculus intubation of the lacrimal duct, the probe set comprising: a probe of a light wire which can be readily deflected through an angle of at least 90 degrees to permit the probe to pass from the nasolacrimal duct to the inferior meatus, the probe having an enlarged end portion which is rounded to limit the possibility of damage to tissue when the probe is inserted; and a very flexible tube of minimal rigidity having a first end attached to an end of the probe remote from the end portion and having an outside diameter comparable to that of the end portion so that in use the probe can be inserted and used to draw the tube into the lacrimal duct.
