Can Mix-and-Match lenses improve vision after cataract surgery?
NCT ID NCT07740590
First seen Jul 31, 2026 · Last updated Jul 31, 2026
Summary
This study follows adults with age-related cataracts who receive different types of intraocular lenses (IOLs) during surgery—either the same bifocal lens in both eyes or a mix of bifocal, EDOF, and monofocal lenses. Researchers will track how well patients adapt to their new vision over six months, measuring visual quality, satisfaction, and daily functioning. The goal is to understand which lens combinations offer the best visual outcomes and patient experience.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Multifocal intraocular lenses (IOLs) implanted during cataract surgery, including bifocal, EDOF, and monofocal combinations.
- What this could lead to
- If successful, this could help eye surgeons choose the best lens combination for each patient, improving visual satisfaction and quality of life after cataract surgery.
- What could go wrong
- This is an observational study, so it won't prove which lens is best. Results may vary widely between individuals, and the custom questionnaire may not capture all aspects of visual adaptation.
