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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study tested a toric intraocular lens implant in 40 children aged 6 to 17 with cataracts and astigmatism (a condition where the eye is shaped like a football). The goal was to see if this special lens could improve vision better than standard surgery. All children had cataract surgery with the toric lens placed in the eye. Researchers measured vision sharpness and eye curvature after surgery to see how well the lens corrected both problems.

What this could mean

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

Active substance
toric intraocular lens implant
What this could lead to
If successful, this could provide a standard way to correct both cataracts and astigmatism in children with a single surgery, improving long-term vision without glasses.
What could go wrong
This is a small, completed trial with only 40 participants, so results may not apply to all children. Risks include surgical complications or the lens not fully correcting astigmatism.
