Flostream: A purpose-built microstent for angle-closure glaucoma

A minimally invasive implant designed specifically for the anatomy of Asian patients.

The Challenge

Angle-closure glaucoma blocks conventional outflow pathways

In angle-closure glaucoma, the trabecular meshwork — the primary drainage site targeted by current minimally invasive devices — is physically blocked. This means existing MIGS solutions cannot be applied, leaving patients with limited surgical options and clinicians without a suitable minimally invasive tool.

Why existing MIGS fail for angle-closure patients

Limited visualisation and access to the trabecular meshworkadd

When the angle is closed, the iris obstructs the view and physical path to the trabecular meshwork — the target of conventional MIGS — making accurate placement difficult.

Implant obstruction after placementadd

Even if a device can be placed, the closed angle can obstruct the implant, blocking outflow and undermining long-term efficacy.

Dysfunctional downstream collector channelsadd

Downstream collector channels may no longer be functional in angle-closure disease, and devices that rely on the conventional outflow pathway may not restore drainage.

Risk of endothelial cell lossadd

Anterior chamber implants carry a risk of corneal endothelial cell loss — a concern heightened in the more crowded anatomy of angle-closure patients.

Differentiation

What makes Flostream different

globe_asia

Built with Asian anatomy in mind

Angle-closure glaucoma is most prevalent in Asian populations, where shallower anterior chambers make conventional MIGS devices unsuitable.

route

Alternate drainage pathway

Flostream creates drainage independent of the trabecular meshwork, bypassing the blocked outflow pathway entirely. This anatomy-agnostic approach is intended to function in eyes where the angle is closed and conventional MIGS access is not possible.
