This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.

What is this trial?

This trial is testing a new irrigation system called the Tran cannula during cataract surgery for people who have both a cataract and pseudoexfoliative glaucoma — a type of glaucoma caused by flaky material that builds up in the eye. The Tran cannula is designed to clean away this material during surgery, which may help lower the pressure inside your eye better than standard irrigation methods.

People with pseudoexfoliative glaucoma often have more complicated cataract surgeries with extra risks. Researchers want to see if this new treatment can clean the eye more effectively and reduce eye pressure more successfully than current techniques.

Do you qualify?

You likely qualify if…

you have been diagnosed with both a cataract and early-to-moderate pseudoexfoliative glaucoma
you are scheduled for cataract surgery only (not other eye procedures at the same time)
your eye pressure is between 21 and 33 mmHg without treatment
you have had reliable vision field tests and eye imaging showing glaucoma damage
you have not had eye surgery or laser treatment in the past 12 months

You likely don't qualify if…

you have had other eye problems besides cataracts or mild dry eye
you have had eye surgery or trauma in the last 12 months
your vision is very poor (worse than being able to count fingers)
you have significant nearsightedness or farsightedness, or very thin or thick corneas
you have closed-angle glaucoma, angle-closure disease, or other types of glaucoma besides pseudoexfoliative glaucoma

What participation looks like

You will be randomly assigned to receive cataract surgery with either the new Tran cannula cleaning system or the standard augmented irrigation method. Your surgeon will perform the cataract surgery using your assigned technique, and the research team will measure your eye pressure and monitor your eye health before and after the procedure to compare how well each method works.
