Prospective randomised comparison of external dacryocystorhinostomy with and without silicone intubation

DCR without silastic intubation is less expensive than DCR with silastic intubation in primary uncomplicated NLDO, and has a similar success rate. DCR with silastic intubation may create increased burden for patients in the form of more post-surgical follow-up visits. In cases of uncomplicated primary NLDO, the use of silastic intubation in DCR may be unnecessary.
