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 Results may not be published yet.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 new device called EYESTAR 900 that uses light to measure the eye's dimensions. Researchers compared its accuracy to the current standard device in 116 volunteers and patients. The goal was to see if the new device could provide more reliable measurements for planning cataract surgery.

What this could mean

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

Active substance
EYESTAR 900 optical biometry device
What this could lead to
If successful, this device could provide more precise eye measurements for cataract surgery, potentially improving surgical outcomes.
What could go wrong
This is a completed device validation study, not a treatment trial. The device may not offer significant advantages over existing methods.
