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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compared two new iCare tonometers (ST500 and IC200) against standard devices to see if they measure eye pressure accurately. Researchers tested 122 adults with different eye pressure levels. The goal was to see if the new devices meet strict accuracy standards, which could make eye pressure checks faster and easier for patients.

What this could mean

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

What this could lead to
If successful, these tonometers could provide a faster, easier way to measure eye pressure, helping doctors diagnose and manage glaucoma more efficiently.
What could go wrong
This is a small, completed device comparison study, not a treatment trial. It only checks accuracy against existing tools, so it won't change how glaucoma is treated directly.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts
