• Previously, the standard procedure in the treatment of patients having had unsuccessful lacrimal surgery has been Jones tube bypass, regardless of the anatomic site of obstruction. However, many of these patients may be treated by a reconstructive approach, namely, the canaliculodacryocystorhinostomy operation. Dacryocystography is helpful in determining which of these patients are amenable to this treatment modality. Success rates are encouraging and eliminate the necessity of a permanent prosthesis and long-term follow-up.
