BACKGROUND: After performing endoscopy of the lacrimal passage, the endoscopic system can be connected to an erbium-YAG laser if the indications are appropriate. MATERIALS AND METHODS: In a bi-center study we performed laser dacryoplasty in 53 cases out of 261 endoscopy procedures (18 stenoses of the canaliculi, 19 stenoses of the sac, 9 stenoses of the nasolacrimal duct, 9 restenoses following DCR). In 35 cases an examination was done and in all 53 cases the results were obtained by means of a questionnaire. RESULTS: Epiphora and irrigation were improved in more than 75%. CONCLUSION: Suitable indications are small stenoses in the sac or duct membranes following DCR. Laser dacryoplasty is a promising method, but more studies still need to be conducted to obtain long-term results. The technical system must also still be improved to make it easier to handle.
