What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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 Results may not be published yet.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
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

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 is testing whether a special eye scanner (OCT) can help fit scleral contact lenses more accurately than the usual method. Researchers will enroll 258 people with conditions like keratoconus or scarred corneas. Each participant will have lenses fitted both the standard way and with OCT guidance, and the fit quality will be compared.

What this could mean

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

Active substance
OCT-guided scleral lens fitting
What this could lead to
If successful, this could make scleral lens fittings faster and more accurate, improving comfort and vision for people with irregular corneas.
What could go wrong
This is an early-stage study comparing two fitting methods; it does not test a new treatment. The results may not change current practice if OCT does not prove clearly better.
