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.

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 Results may not be published yet.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

Details not published

Summary

This study tested whether orthokeratology (OK) lenses, worn overnight, can slow the progression of nearsightedness (myopia) in children aged 8 to 15. The lenses reshape the cornea to change how light focuses on the retina. Researchers measured changes in eye length and retinal focus over one year in 53 participants. The goal was to see if OK lenses reduce the need for stronger glasses over time.

What this could mean

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

Active substance
orthokeratology lenses
What this could lead to
If successful, this could confirm that special contact lenses worn overnight can slow down worsening nearsightedness in children.
What could go wrong
This is a small, completed study with only 53 participants. Results may not apply to all children, and risks like eye infections from lens use exist.
