Can laser precision improve astigmatism correction during cataract surgery?
NCT ID NCT05750862
First seen Aug 06, 2026 · Last updated Aug 07, 2026 · Updated 1 time
Summary
This study tests whether a laser-guided system can mark the correct position for a toric intraocular lens more accurately than the traditional manual ink method during cataract surgery. The trial involves 30 patients with corneal astigmatism who are having femtosecond laser-assisted cataract surgery. The main goal is to measure how closely the laser marking matches the intended axis and how it compares to manual marking, with the hope of improving astigmatism correction and reducing lens repositioning.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Topography-guided automatic laser marking of the intraocular lens axis during femtosecond laser-assisted cataract surgery, compared with manual ink marking.
- What this could lead to
- If successful, this could lead to more precise alignment of toric intraocular lenses, potentially improving astigmatism correction and reducing the need for lens repositioning after cataract surgery.
- What could go wrong
- The trial is small (30 participants) and non-randomized, so results may not apply broadly. Laser marking might not be more accurate than manual marking, and there are risks inherent to any eye surgery, such as infection or inflammation.
