A gel plug for tear ducts may stop post-surgery dry eye
NCT ID NCT07796178
First seen Sep 01, 2026 · Last updated Sep 02, 2026 · Updated 1 time
Summary
This trial tests whether Lacrifill, a gel placed in the tear duct to block tear drainage, can reduce dry eye symptoms in people who have had cataract surgery. Participants receive either Lacrifill or standard saline eye drops, and researchers compare eye discomfort scores over three months. The goal is to see if the gel keeps the eye moist and prevents the dryness that often follows surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lacrifill, a gel made of crosslinked hyaluronic acid that is placed in the tear duct to keep tears on the eye
- What this could lead to
- If it works, Lacrifill could offer a simple, non-drug way to prevent or ease dry eye discomfort after cataract surgery.
- What could go wrong
- This is a small, early-stage trial with only 40 participants, so results may not apply to everyone. The gel could cause irritation, infection, or the device might not stay in place.

Inclusion Criteria: * Adults ≥18 years of age. * Have the potential of 20/40 visual acuity or better post-cataract surgery. * have cataract surgery scheduled for both eyes * Corneal staining score of ≥3 on the original National Eye Institute (NEI; 0-15 total score) staining scale in the study eye. * willing to discontinue contact lens throughout the study? * pre-treatment OSDI scores of ≤12 (asymptomatic)? Exclusion Criteria: * Known systemic health conditions that are known to alter tear film physiology (e.g., primary and secondary Sjögren's syndrome)? * History of ocular surgery within the past 12 months (excluding cataract surgery) * Anticipated complications from cataract surgery in either eye? * History of severe ocular trauma, active ocular infection or inflammation that is not dry eye-related? * Used Accutane or is currently using ocular medications/treatments outside of study treatments? Artificial tears will be allowed. * Physical meibomian gland treatment withing 1 month of enrollment? * Having any conditions or are in a situation, which in the investigator's opinion, may put the subject at significant risk, may confound the study results, or may significantly interfere with their participation in the study. * Currently pregnant or breast feeding
