The Hydrus Microstent is a flexible, crescent-shaped glaucoma implant that helps fluid drain through the eye’s natural pathway.
How Hydrus works
Placed in Schlemm’s canal via the drainage angle, the device scaffolds and widens a segment of the canal. This improves outflow from the anterior chamber in open-angle glaucoma.
- Inserted through a small incision, often combined with cataract surgery
- Bypasses part of the trabecular meshwork to reduce resistance
- Suitable mainly for mild to moderate open-angle glaucoma
- Not visible externally once implanted
Advantages and considerations
Hydrus can provide greater pressure reduction than some single-stent options. It is still less invasive than traditional filtering surgery.
- May decrease reliance on daily glaucoma drops
- Regular follow-up remains essential to track pressure and optic nerve health
- Less effective for very advanced or angle-closure glaucoma
- Decision to use Hydrus is tailored to target pressure and patient factors
