The sisler lacrimal canalicular trephine

Abstract

The Sisler trephine makes recanalization of a distally blocked lacrimal canaliculus an office procedure as opposed to major surgical microdissection in an operating room setting. The uniform, cylindrically shaped bolus of scar tissue removal makes for a sculptured passageway through the previous obstruction which, with its smooth and clean edges, is less likely to reocclude with time. © 2006 Springer Science+Business Media, Inc.
