    Researchers randomized 100 patients with uncomplicated, primary nasolacrimal duct obstruction to undergo dacryocystorhinostomy (DCR) with or without silastic intubation. After six months, there was no statistically significant difference in the success rate between the two groups, and no complications were observed. The authors concluded that intubation is unnecessary in primary uncomplicated DCR, particularly in developing countries, due to its failure to improve results, higher cost and need for more follow-up visits.
