Lacrimal Trephine [Sisler]

Ultra-Sharp Lacrimal Trephine (Sisler) are used in rotary trepanation of an obstructed canaliculus & biopsy of the conjunctiva or sclera. The device has a blunt and round tip which allows the reduction of the chances of trauma to the surrounding tissue. The micro trephine with dimension .80mm x 38mm is long enough to span the length of the normal lacrimal canaliculus.
