[Forward efficacy of lacrimal passage obstruction treated by double frequency YAG laser].
OBJECTIVE
To study the forward efficacy of lacrimal passage obstruction in different location treated by frequency-doubled YAG laser.


METHODS
The forward efficacy of obstruction at different lacrimal passage located in 66 eyes from 64 cases treated by frequency-doubled Nd:YAG laser respectively were analyzed.


RESULTS
The forward cure rate of stenosis of the puncta, dacryogogatresia, and common lacrimal duct stenosis is 100%, 94% and 89% respectively. As for dacryocystorhinostenosis, lower to 29%.


CONCLUSIONS
Frequency-doubled YAG laser is more fit for puncta stenosis, dacryogogatresia and common lacrimal duct stenosis. Choosing the other treatment is suitable to dacryocystorhinostenosis which is accompanied by chronic dacyocystitis for YAG laser' s poor forward efficacy.
