A monocanalicular stent proved safe, effective and easy to use in reconstructing traumatic canalicular lacerations, according to a study.
Investigators set out to assess the safety and efficacy of the Mini-Monoka monocanalicular intubation stent (FCI Ophthalmics).
"It is easy to use, carries a minimal risk of injury to the non-lacerated canaliculus, and results in high anatomical and functional success rates," the study authors said.
The study included 19 patients (mean age: 34 years) with traumatic canalicular lacerations who underwent reconstruction surgery with the stent. Subjective clinical findings (epiphora) and objective findings tear meniscus level, dye disappearance test and lacrimal irrigation) after stent removal determined surgical outcomes.
Five patients had injury to the upper canaliculus and 14 patients had injury to the lower canaliculus.
Study results showed that the stent was successfully implanted in all eyes. Most patients had satisfactory postoperative eyelid position. Stents were implanted for a mean duration of 5 months; mean postoperative follow-up was 13 months.
No eyes had premature stent extrusion. Data showed that 94.7% of patients had normal functional drainage after stent removal. Eyes showed normal patency and no narrowing or reflux with syringing, the authors reported.
