[Conjunctival dacryocystorhinostomy in the treatment of proximal lacrimal drainage obstruction].

The problem of reconstruction of the lacrimal drainage system in cases of obliteration of both lacrimal points and/or both lacrimal canaliculi remains one of the most difficult in dacryology. The most common and effective operation for this pathology is Conjunctival dacryocystorhinostomy using tubes developed by L. Jones in 1962. However, wearing the tube for a long time and the complications associated with it can cause dissatisfaction with the treatment, even if the surgery was successful. The surgery technique and the tubes design have undergone numerous modifications to increase the amount of positive outcomes and reduce the number of complications. The results of original studies on this problem were analyzed revealing a lack of knowledge about the optimal design and material of the implant. There are few studies aimed at developing methods that ensure persistent preservation of the anastomosis after tube removal.
