NCT ID NCT07755189
First seen Aug 10, 2026 · Last updated Aug 11, 2026 · Updated 1 time
Summary
This study follows adults having cataract surgery who choose either a trifocal or monofocal intraocular lens implant. It asks whether one type leads to more difficulty or visual disturbances, like glare or halos, when driving at night. Participants must be licensed drivers with regular night-driving habits. The main measure is a questionnaire about night-driving difficulty three months after surgery, with additional tests of vision and glare adaptation.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Trifocal intraocular lens (AcrySof IQ PanOptix TFNT00) or monofocal intraocular lens (Alcon)
- What this could lead to
- If trifocal lenses prove as safe for night driving as monofocal ones, more cataract patients could choose them without worrying about glare or halos.
- What could go wrong
- This is an observational study, not a randomized trial, so results may be influenced by patient choice. Also, outcomes rely on self-reported questionnaires, which can be subjective.
