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 This study
The trial has finished. Results may not be published yet.
Stopped early
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 tested a special laser device (CAPSULaser) to create a precise opening in the lens capsule during cataract surgery in 24 patients with intumescent cataract, a type of dense cataract that can make surgery tricky. The goal was to see if the laser could make the opening more accurate and reduce complications. The study is complete, but results are not yet published.

What this could mean

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

Active substance
selective laser capsulotomy device (CAPSULaser)
What this could lead to
If successful, this laser technique could make cataract surgery safer and more precise for people with a specific type of dense cataract.
What could go wrong
This was a very small, early study with only 24 participants. The results may not apply to all cataract patients, and the device may not be widely available.
