97th DOG Annual Meeting 1999



K. Müllner, G. Wolf

Background: Since four years, endoscopes with which the mucosa and disorders of the lacrimal drainage system can be examined directly, are available. The wish to treat lacrimal disorders with endoscopes and laser have remained.

Patients and Methods: Since September 1997 45 patients were treated with a KTP-laser (quasi-cw mode, wavelength 532 nm and 10 W power). with aquired postsaccal stenosis. 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: 35 patients are patent and have no symptoms, 5 patients have watering by cold weather and 4 patients had a restenosis. Follow up range between 2 months and 17 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 is possible.
