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 Results may not be published yet.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

Summary

This study tested whether a computer-based tutorial (CatInfo) given before the doctor visit helps cataract surgery patients understand the procedure better and shortens the time needed for the doctor to explain it. 90 adults scheduled for cataract surgery were randomly assigned to either watch the tutorial or have only a standard discussion with the physician. Researchers measured patients' knowledge and attitudes before and after surgery.

What this could mean

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

Active substance
computer-based tutorial (CatInfo tool)
What this could lead to
If successful, this approach could make the informed consent process more efficient and improve patient understanding before surgery.
What could go wrong
This is a small, completed study with only 90 participants, so results may not apply to all hospitals or patient groups. The computer tool may not work as well for people with vision or hearing problems.

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