Can a simple calculator make laser eye surgery sharper?
NCT ID NCT07605221
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether using a special calculation tool (called a nomogram) helps doctors correct astigmatism more precisely during laser eye surgery. One hundred adults with astigmatism will be treated, and their vision will be checked over three months. The goal is to see if the nomogram leads to better results than standard methods.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- nomogram (a calculation tool used during laser eye surgery)
- What this could lead to
- If it works, this could help surgeons correct astigmatism more accurately during laser eye surgery.
- What could go wrong
- This is a small, early-stage study with only 100 participants. The nomogram may not improve outcomes significantly, and results may not apply to all patients.
