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 Results may not be published yet.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
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 tests three AI chatbots—ChatGPT 4o, GPT-5, and DeepSeek—on their ability to read eye scans from 100 cataract patients. The AI will try to extract key measurements, recommend the right lens implant, and predict vision after surgery. No treatment is given; the goal is to see how well AI can help doctors plan cataract surgery.

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, this could show that AI can reliably read eye scans and help doctors plan cataract surgery, potentially saving time and reducing errors.
What could go wrong
This is a small, retrospective study with only 100 participants. AI may not perform as well in real-world settings or with different types of eye scans.

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