Ohmmeter-guided nasolacrimal intubation.
Retrieval of steel probes via the inferior meatus of the nose in monocanalicular and bicanalicular nasolacrimal intubation can be a tricky maneuver, possibly complicated by bleeding from lacerated soft tissue around the inferior turbinate. Using a low-voltage device (essentially, an ohmmeter) to assure contact between the retrieval hook and the distal end of the steel probe greatly facilitates the procedure.
