Comparing methods for tear duct surgery
Part of Ear, nose & throat, Eyes & vision clinical trials.
This trial compares different ways to manage the flap during external dacryocystorhinostomy (a surgery to clear blocked tear ducts). It may help if you have a blocked tear duct, a tear sac infection or a tear sac cyst or fistula.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have chronic dacryocystitis (long-term infection of the tear sac).
- You have a primary blockage of the tear duct that leads from the eye to the nose.
- You have a lacrimal mucocele (a cyst in the tear sac filled with mucus).
- You have a lacrimal fistula (an abnormal opening from the tear sac to the skin).
- You are at least 5 years old and in good health for general anesthesia.

This trial tests whether adding dexmedetomidine or magnesium sulfate to lidocaine makes numbing the eye more effective for tear-duct surgery. The goal is to find which combination provides better pain control during surgery.
This study tests whether a medication called dexmedetomidine can reduce the amount of anesthesia needed during tear duct surgery (DCR), possibly making the procedure safer and more comfortable.
This trial tests whether using four balloon inflation points during tear duct surgery works better than the standard two points for people with blocked tear ducts. It aims to improve tear drainage and reduce symptoms.
This study compares two medications (hyaluronic acid and mitomycin-C) used during a surgery to open a blocked tear duct. It aims to see which one helps the new tear channel stay open longer, especially for people with chronic eye discharge or tearing.
This study tests if adding a medicine called 5-FU to standard tear duct surgery helps people with a small tear drainage sac get better results. It might be an option if you have a blocked tear duct and a very small sac.
This trial tests a new light-activated gel to help keep the tear duct open after standard surgery. It may reduce the chance of the duct closing again.
