[Nasolacrimal stent: modifications to Ho-Young Song's technique].
OBJECTIVE
To introduce modifications to Song's technique in the treatment of nasolacrimal occlusion by means of a polyuretane stent.


METHODS
Thirty five polyuretane stents were placed under fluoroscopic guidance in 32 patients diagnosed with total and partial nasolacrimal occlusion.


CONCLUSIONS
Technical success rate was 90%. Sixteen right and nineteen left nasolacrimal systems were probed. The introduction of a guidewire through the lower punctum, the use of a Ritleng guide, a Crawford hook and ocular protectors are modifications of Song's procedure that may help in successfully performing this technique in a fast and easy way.
