Abstract BACKGROUND. Canalicular injuries and anomalies are relatively common. Despite this, controversy still exists regarding the indications for surgery and best surgical methods. The most favourable intervention would be one that is simple, associated with a high level of subjective and objective outcome, and does not threaten the uninjured or unaffected part of the lacrimal drainage system. This study assesses outcomes of intervention with the Mini Monoka silicone monocanalicular lacrimal stent. METHOD. A single cohort, hospital-based study with retrospective and prospective components. Participants were all identifiable patients at Bristol Eye Hospital in whom the Mini Monoka silicone monocanalicular stent was used for any indication. Retrospective analysis of patient records for all related pre-operative, operative and postoperative data was performed. Prospective analysis of subjective outcome via confidential patient questionnaire and objective outcome via clinical examination was performed. RESULTS. Complete data were obtainable in 13 patients (14 canaliculi) of the identified 22 patients (23 canaliculi). Follow-up was from 12 to 70 months (mean 39 months). A high level of subjective outcome was noted with no patients experiencing significant or disabling symptoms. In terms of objective outcome, 79\% achieved canalicular patency. The main complications with this technique were premature stent loss (29\%) and stent migration (14\%). CONCLUSIONS. The Mini Monoka monocanalicular stent is a safe, effective and simple surgical technique that, unlike bicanalicular procedures, does not threaten the uninjured / unaffected part of the lacrimal drainage system.
