The Claim
Day-1 intraocular pressure spikes following cataract surgery do not significantly account for differences in long-term visual field progression between patients implanted with the Hydrus Microstent and those undergoing cataract surgery alone.
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.
A temporary rise in eye pressure on the first day after cataract surgery does not explain why patients with the Hydrus Microstent have different long-term changes in their peripheral vision compared to patients who had cataract surgery alone.
See the scientific wording
Day-1 intraocular pressure spikes after cataract surgery do not significantly explain differences in long-term visual field progression between patients receiving the Hydrus Microstent and those receiving cataract surgery alone, indicating that acute postoperative pressure changes are not the primary mechanism of benefit.
The stent keeps eye pressure low over time, which prevents damage to the nerve cells in the back of the eye that send visual signals to the brain. This keeps vision stable for years, even if pressure briefly rises right after surgery.
What the research says
1 studyStudy: Effect of intraocular pressure control on visual field progression in the HORIZON trial.
The study found that a temporary spike in eye pressure right after surgery doesn’t explain why some patients keep better vision for years — what matters more is how low their eye pressure stays over time. The stent helps because it lowers pressure long-term, not because it prevents short-term spikes.
