The use of membrane-peeling vitreoretinal forceps to facilitate lacrimal sac dissection in external dacryocystorhinostomy is demonstrated. The closed vitreoretinal forceps are advanced via the upper punctum and canaliculus, through to the lacrimal sac. They are then opened maximally providing two points of elevation. This maneuver allows for easier identification of the plane of dissection during lacrimal flap creation. It is especially useful with complex anatomy and for junior trainees in helping to orient the dissection. No tissue or instrument damage has been noted, and because many ophthalmic units have a vitreoretinal service, the forceps may be readily available at no extra cost.
