Topical numbing drops to reduce pain during tear duct testing
Part of Eyes & vision clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be 18 years or older, any sex
- Have watery eyes (tears running) that require tear-duct probing and irrigation on both lower eyelids
- Be willing/able to get the procedure at the study site or participating doctor office
- Do not have a known allergy to proparacaine (a numbing eye drop)
- Do not have prior scarring, past surgery, or radiation to the tear drainage (nasolacrimal) system
- Have no signs that the tear-duct test shows a blockage or reflux, and you can understand and follow instructions

This study tests whether low-dose atropine eye drops, given nightly for 7 days, can reduce excessive tearing (epiphora) in adults. If you have bothersome tearing not caused by dry eyes, this treatment might offer relief.
This trial tests a new eye drop (acoltre mon) to see if it helps people who have both dry eyes and nerve-related eye pain. The drops may increase tear production and reduce burning or light sensitivity.
This study tests new artificial tear drops to see if they are safe and effective for people with dry eye disease. If you have dry eyes, these drops might help reduce symptoms and improve eye comfort.
This study compares two ways to treat a blocked tear duct in babies: gentle massage of the tear sac area versus a quick probing procedure. It aims to find which method works better to clear the blockage and reduce watery eyes.
This study tests whether over-the-counter lubricating eye drops can improve dry eye symptoms and eye comfort. It compares the drops to no treatment to see how well they work.
This trial tests a new eye drop (acoltrepon) to see if it helps people with stage 1 neurotrophic keratopathy (a condition where the cornea's nerves are damaged, causing dry eyes and vision problems) and low tear production. It aims to improve signs like corneal staining and symptoms of discomfort.
