Hyaluronic acid vs mitomycin-C in tear duct surgery
Treatments studied
Part of Eyes & vision clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- You have a long-term blocked tear duct (called primary acquired nasolacrimal duct obstruction) that causes tearing or discharge.
- You do not have an active eye infection or abscess at the inner corner of your eye.
- You have not had a failed or repeat surgery for this blockage before.
- You don't have uncontrolled diabetes or other conditions that affect wound healing.

Other trials that look related to this one.
This Phase 4 trial studies whether numbing eye drops (proparacaine 0.5%) can reduce pain during a procedure called probing and irrigation of the tear drainage system. If you need this test for ongoing watery eyes, the trial may help make the procedure more comfortable.
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.
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 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 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 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.
