NCT ID NCT07346456
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 102 cataract patients whose corneas have a higher-than-normal back curve (posterior corneal elevation ≥15 µm). Researchers compared 13 different formulas used to calculate the right lens power for surgery, to see which one gives the most accurate vision results. The goal is to help surgeons pick the best formula for these patients.

What this could lead to
If successful, this study could help eye surgeons choose the best formula for cataract patients with a specific corneal shape, improving their vision after surgery.
What could go wrong
This is a small observational study (102 people) that only looks back at results, not a controlled trial. The findings may not apply to all patients or surgeons.
