Eye surgery showdown: device vs manual marking for sharper vision
NCT ID NCT07696468
First seen Jul 10, 2026 · Last updated Jul 16, 2026 · Updated 2 times
Summary
This trial tests whether a device called OcuLign, which automatically adjusts for eye rotation during SMILE surgery, corrects astigmatism better than the standard manual marking method. Adults aged 18 to 40 with stable myopia and astigmatism will have one eye treated with each method. The goal is to see which approach leaves less residual astigmatism three months after surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- OcuLign-assisted cyclotorsion control (device procedure)
- What this could lead to
- If OcuLign proves better or equal to manual marking, it could become a standard tool for more precise astigmatism correction during SMILE surgery.
- What could go wrong
- This is a small, early-stage trial with only 52 participants. The improvement may be minimal, and results may not apply to all patients or surgeons.
