A-stream
A minimally invasive glaucoma implant
that lowers eye pressure
It creates a new outflow path for aqueous humor inside the eye to help control eye pressure. At 6 mm, it keeps the incision minimal, and its 100 μm inner lumen drains aqueous humor at a steady rate.

How it works
Creating a path for aqueous outflow
In glaucoma, aqueous humor can't drain properly from the eye, so eye pressure rises and damages the optic nerve. A-stream places a tiny tube linking the anterior chamber to the subconjunctival space, giving aqueous humor a steady way out.
01
Insert
The implant is placed in the anterior chamber through a minimal corneal incision.
02
Anchor
A 1 mm wing catches on the sclera to keep the implant from shifting after insertion.
03
Drain
Aqueous humor flows through the 100 μm lumen into the subconjunctival space.
04
Regulate
The lumen limits outflow, helping prevent a sudden drop in eye pressure.
Features
Every number reflects a design decision
6mm
Minimally invasive design
A minimally invasive glaucoma surgery (MIGS) implant made in Korea. Its 6 mm size reduces the incision, easing tissue damage and recovery.
100μm
Pressure reduction by design
The 100 μm lumen drains aqueous humor to lower eye pressure. The width of the tube itself is what limits outflow.
1mm
Wing anchoring
A 1 mm wing keeps the implant from moving inside the eye after insertion. A stable position means steady outflow.
Class III
Medical-grade silicone
Approved as a Class III medical device. Made from biocompatible medical-grade silicone, it keeps its shape after insertion.
