The Claim
The Hydrus Microstent is associated with a 44.6% slower rate of visual field deterioration over five years compared to cataract surgery alone in patients with glaucoma and cataract, and this difference is not fully explained by mean intraocular pressure reduction.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Patients with glaucoma and cataract who receive the Hydrus Microstent during cataract surgery experience a 44.6% slower decline in their peripheral vision over five years compared to those who receive cataract surgery alone. This difference cannot be fully accounted for by lower eye pressure alone.
See the scientific wording
The Hydrus Microstent is associated with a 44.6% slower rate of visual field deterioration compared to cataract surgery alone over five years in patients with glaucoma and cataract, but this benefit is not explained by differences in mean intraocular pressure alone, suggesting that the device’s effect is mediated by more nuanced IOP dynamics.
The stent keeps eye pressure from spiking or dropping too much, which prevents repeated tugging and squeezing on the nerve fibers that carry vision signals to the brain. This lets those nerves survive longer and keeps vision from getting worse.
What the research says
1 studyStudy: Effect of intraocular pressure control on visual field progression in the HORIZON trial.
Patients who got the tiny stent during eye surgery lost their vision much slower than those who only had cataract surgery—but not because their eye pressure was just lower on average. It’s because the stent helped keep pressure more stable over time, which better protected their vision.
