Background: Since five years, endoscopes for examination of the
mucosa and disorders of the lacrimal drainage system are available. The
wish to treat lacrimal disorders with endoscopes and laser have remained.
Patients and Methods: Since September 1997 78 patients with aquired
postsaccal stenosis were treated with a KTP (Kalium-Titanium-Potassium)-
laser (quasi-cw mode, wavelength 532 nm and 10 W power). A transcanalicular
laserassited DCR was performed.The aim was to perform a bony window of
at least 5x5 mm in diameter. Bicanalicular intubation into the nose was
performed and was left for at least three months.
Results: 68 patients have patent lacrimal drainage system and no
symptoms, 6 patients have watering by cold weather and 4 patients had
a restenosis (follow- up range: 12 and 36 months). With the KTP- Laser
is it possible to perfom bony windows and penetrate thick membranes Conclusions:
With the KTP-laser a successfull transcanalicular laserassisted DCR with
good results is possible. Key words: lacrimal stenosis, laser surgery,
