In lacrimal surgery, monocanalicular or monocanaliculonasal intubation is an indispensable tool, but silicone probe placement often proves difficult in complex situations. LacriJet (FCI S. A. S.—France Chirurgie Instrumentation, Paris, France, compare figure 1) represents a novel preloaded monocanalicular nasolacrimal intubation system reducing the number of surgical steps (compare figure 2), which may be beneficial, especially in complex situations. This study aims to investigate the efficiency of LacriJet.

LacriJet shooter system. Preloaded silicon stent (red circle) in the LacriJet, which can be inserted into the lacrimal duct via the open shooting system (yellow circle).

Figure 2

Implantation by using the LacriJet: step-by-step implantation (A–F) by using LacriJet with probing the tear duct (A), implantation of the silicon stent (B, C), and shooting the stent by LacriJet (D) with following manual positioning (E) until the probe is correctly located in the patients lower lacrimal punctum (F).

In a retrospective study between 2019 and 2020 at the Department of Ophthalmology, University of Cologne, 216 performed LacriJet intubations …
