Investigational Hydrus Microstent device study for Refractory Glaucoma

Trial ID:
IRB-18-7190
Quang H. Nguyen, M.D.
This study is testing the safety and effectiveness of the experimental Hydrus Microstent Glaucoma Implant to lower eye pressure for people with refractory glaucoma. Refractory glaucoma is a type of glaucoma where the eye pressure is still too high even after having other procedures and using multiple medications to treat the glaucoma. The study requires 12 visits over 1 year.

Inclusion Criteria

  • Be at least 45 years of age.
  • Have a diagnosis of refractory open-angle glaucoma.
  • Have best corrected vision of 20/80 or better in the study eye

Exclusion Criteria

  • Have had previous LASIK or PRK surgery
  • Have best-corrected vision worse than 20/200 in the non-study eye
  • Be unable to complete a reliable visual field test
  • Have age-related macular degeneration (AMD)
  • Be using oral glaucoma medication
  • Have a known or suspected allergy to nickel

Additional Info

  • The Hydrus Microstent is a tiny, tube-like device that is about the size of an eyelash. It is made from a super-elastic, biocompatible metal called nitinol, a material also used in many other medical devices that are placed in a number of other parts of the body such as the heart and blood vessels. The Hydrus Microstent is designed to be inserted into the primary fluid canal of the eye to open the channel and allow blocked fluid to flow more freely.
