Also to know is, is tear duct surgery necessary?
Treatment of Tear System Blockage When the nasolacrimal duct, the tube which drains tears into the nose, is blocked a surgical procedure is usually required.
Correspondingly, how long is recovery from DCR surgery?
After a DCR procedure we generally advise patients not to fly for 2 − 3 weeks, to avoid hot drinks for 36 hours, and not to blow their nose for 2 weeks. Patients should not undertake strenuous exercise for at least ten days, and should try to sleep with their head elevated on an extra pillow if possible.
The success rate of external DCR for patients with previous episodes of dacryocystitis was 82.7%, compared to 83.4% for patients without previous episodes of dacryocystitis. The success rate in patients without previous lacrimal duct surgery was 88.5% compared to 74.3% for patients with previous lacrimal duct surgery.
