Laser touch-up may sharpen blurry vision after cataract surgery
NCT ID NCT04712318
First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time
Summary
This trial tests whether a laser procedure called Relex-Smile can correct leftover nearsightedness or farsightedness in people who had cataract surgery six months earlier. About 130 participants with blurry vision after receiving a trifocal lens implant will undergo the laser treatment. The goal is to see if the procedure safely improves visual sharpness and reduces the need for glasses.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a laser procedure called Relex-Smile that reshapes the cornea to correct leftover nearsightedness or farsightedness
- What this could lead to
- If it works, this could offer a way to reduce or eliminate the need for glasses after cataract surgery.
- What could go wrong
- This is a single-center trial with no comparison group, so results may not apply broadly. Risks include infection, corneal haze, or under- or over-correction.
