Microsurgery and lacrimal system.

Where epiphora results from canalicular obstruction, it is usually possible to cure the patient by reconstructing the canaliculi themselves. Resort to artificial bypass tubes is thus not often necessary. This paper discusses the role of the operating microscope in facilitating reconstruction of the lacrimal canaliculi so that longer segment of obstructed canaliculus can be reopened and more accurate reconstitution of the anatomy achieved. The place of fibre optics is outlined. Easier techniques for repairing lacerated canaliculi are described.
