What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early This study
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study compared a new device called miCOR, which uses low energy to break up cataracts, to standard cataract surgery. About 402 adults with cataracts were planned to take part. The study was terminated early, so we don't have full results on whether the new device is better or safer.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
miCOR System device
What this could lead to
If successful, this could offer a safer, less energy-intensive way to remove cataracts during surgery.
What could go wrong
The study was terminated, so we have limited data. The device may not be better than standard methods, and any new device carries surgical risks.
