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 atropine eye drops can reduce excessive tearing (watery eyes) caused by various reasons. If you have watery eyes that bother you daily, these drops might help by decreasing tear production.
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 study compares two different eye drop lubricants to see which one works better for people with dry eye symptoms. You would use only the study drops for the whole time and attend a few visits to check your eyes.
This trial tests a new eye drop called PRO-240 versus Optive artificial tears in healthy adults. You will attend several visits over a few weeks and use the assigned drops as directed. The goal is to see if the new drop is as safe and comfortable as the standard one.
This study compares two treatments for blocked tear ducts in babies: a special eyelid massage versus a gentle probe opening (probing) with a local anesthetic cream. It helps find out which approach works better and is less stressful.
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.
