Investigational Glaucoma Drainage Implant
Exploring innovative surgical treatments for the world’s leading cause of blindness.
Developing an Investigational Glaucoma Drainage Device for Patients Who Require Surgical Treatment
- Using a stable, biopermeable interface design intended to provide durable pressure reduction to treat moderate-to-severe glaucoma
- Developed in collaboration with leading ophthalmologists and glaucoma specialists
- Fully enrolled feasibility studies are ongoing


Tackling the Leading Cause of Blindness
Glaucoma affects an estimated 4.2 million people in the U.S., making it the most common cause of irreversible blindness. Without treatment, elevated eye pressure can damage the optic nerve, leading to vision loss1.
In early stages, elevated intraocular pressure is managed with daily topical medications. However, poor adherence—often due to medication side effects, complex dosing regimens, cost, and forgetfulness—can lead to disease progression, necessitating surgical intervention in moderate-to-severe cases2.
Surgery is typically a last resort due to significant risks and a high failure rate—up to 50% within five years—after other lower-risk but less effective treatments have been exhausted2.
Seeking a New Solution for Pressure Relief
We are investigating innovative and novel materials and designs that could benefit patients with moderate-to-severe glaucoma by providing an alternative to traditional tube shunt devices.
The implant features a unique reservoir design and specialized material that may reduce fibrosis without requiring antifibrotic drugs during implantation. Additionally, its design is intended to minimize the bleb profile, potentially improving patient comfort and clinical outcomes.
