ClinConnect Summary

This clinical trial is examining a surgical procedure called dacryocystorhinostomy, which is used to treat a blockage in the tear duct system (nasolacrimal duct obstruction). The study aims to find out if using a special material called amniotic membrane during the surgery can improve the success rate compared to the surgery without it. The researchers are currently looking for participants aged 18 and older who have been diagnosed with this blockage and are healthy enough to undergo general anesthesia.

If you choose to participate, you'll undergo the surgery and will need to come back for follow-up visits to check on your recovery. However, there are some conditions that may prevent someone from joining the trial, such as certain eye diseases, previous facial injuries, or being pregnant or nursing. This study is important as it could help improve treatment options for people with tear duct blockages, making the surgery more effective.
