About this study

In plain language

This study compares three devices used for goniotomy, a surgery to help fluid drain from the eye and lower eye pressure. It is for adults with open-angle glaucoma who are having cataract surgery and goniotomy together. The study will compare eye pressure and glaucoma medicine use for up to 6 months after surgery.

The goal of this study is to determine of one of three different devices to perform goniotomy to treat glaucoma at the time of cataract surgery is more or less effective than the others. The primary outcomes are to compare intraocular pressure control and glaucoma medication use up to 6 months after surgery. Participants will under combined cataract surgery and goniotomy. They will have post-operative follow up visits at 1 day, 1 week, 1 month, 3 months, and 6 month

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Who can join

  • Age 18 or older.
  • Have open-angle glaucoma, a disease that damages the eye’s main nerve even though the drainage angle is open.
  • Scheduled for cataract surgery to remove a cloudy eye lens, with goniotomy planned at the same time.
  • Able to understand the study and agree to take part.

Who can't join

  • Have angle-closure glaucoma, in which the eye’s drainage angle is blocked.
  • Have had glaucoma surgery in the eye being studied.
  • Plan to have goniotomy without cataract surgery.
  • Cannot attend follow-up visits at 1 day, 1 week, 1 month, 3 months, and 6 months after surgery.
