  • Active comparator
    Symfony IOL

    The Symfony IOL is a lens designed to provide high quality vision up tp 26 inches reducing the need for glasses after routine cataract surgery in patients with or without astigmatism.

    Device: Symfony IOL

  • Active comparator
    Vivity IOL

    The Vivity IOL is a lens that provides extended range of vision ranging from distance to near reducing the need for glasses after routine cataract surgery in patients with or without astigmatism.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Dec 2023 to primary completion in Oct 2024, 10 months.

Results were first posted in Feb 2025, 3 months after primary completion.

Of 46 non-industry phase 4 interventional studies under Cataract, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 34. This study's 10 months is below that.

Counting every sponsor, half of 54 studies reached it within 17 months; a quarter within 9 and three quarters within 29.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 14, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
