Light-activated gel for tear duct surgery
Part of Eyes & vision clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 75 years old.
- You have chronic dacryocystitis (long-term tear duct blockage and infection) confirmed by a doctor.
- Your tear duct blockage is in the main nasal tear duct, not in the tiny canals near the eye.
- You have not had previous surgery for this condition.
- You are not currently having an acute flare-up of the infection.

This trial tests a new type of dissolvable stent that slowly releases medicine to treat chronic tear duct infections that have come back after previous surgery. It may help people who need another treatment option.
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 study tests a gel placed into the tear drain to treat dry eye in people who are also getting cataract surgery. You may be able to join if you have dry eye and are having cataract surgery.
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.
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.
