Upper Tear Drain Plug for Dry Eye After Lower Plug
Part of Eyes & vision clinical trials.
This trial tests whether adding a plug to your upper tear drain (in addition to an existing lower plug) helps severe dry eye. It may improve comfort by reducing tear loss.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your lower tear drain is already plugged (with a plug or sealed by cautery) and confirmed sealed under microscope
- Your upper tear drain works normally
- You have aqueous-deficient dry eye—a type caused by low tear production (such as Sjögren's syndrome, graft-versus-host disease, or primary dry eye)
- You are 18 years or older
- You have moderate-to-severe dry eye symptoms (OSDI score above 13) plus signs like poor tear break-up time, corneal/conjunctival staining, or low Schirmer test results
- You do not have an active eye infection and can provide written consent

Other trials that look related to this one.
This trial tests if using special eye drops (cyclosporine) along with tiny plugs placed in the tear ducts can improve dry eye symptoms in people with Sjögren's syndrome. The goal is to see if this combination works better than the drops alone.
This study tests whether a special eyelid massage technique using a support plate can help unblock and improve meibomian glands—small glands in your eyelids that produce tear oil. If your glands are blocked or not working well, it may be causing your dry eyes, and this treatment might help.
This trial tests a new eye drop called DFL24498 to see if it helps people with dry eye disease. You may qualify if your dry eye is moderate to severe and other treatments haven't worked well for you.
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 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 study tests a new eye drop formula to see if it safely improves dry eye symptoms. It may be a good option if you have been diagnosed with dry eye and have limited tear production.
