Summary

The purpose of this study is:

* To report the success proportions for the treatment of persistent nasolacrimal duct obstruction for three surgical procedures: balloon catheter dilation, nasolacrimal intubation, and simple probing.
* To obtain descriptive data regarding symptoms and quality of life in patients receiving each type of surgical procedure, and to compare success proportions between patients undergoing balloon catheter dilation and those undergoing nasolacrimal intubation.

Conditions

  • Nasolacrimal Duct Obstruction

Interventions

PROCEDURE

Nasolacrimal balloon catheter dilation

Balloon catheter nasolacrimal duct dilation consists of punctal dilation of at least one punctum and the passage into the nose of a semi-flexible wire probe with an inflatable balloon on the tip.

PROCEDURE

Nasolacrimal intubation

Nasolacrimal duct intubation consists of punctal dilation of at least one punctum with the passage of a flexible lacrimal probe into the nose and the placement of a temporary stent in the nasolacrimal duct.

PROCEDURE

Nasolacrimal duct probing

Simple nasolacrimal duct probing consists of punctal dilation of at least one punctum and the passage of a probe into the nose.
