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 Results may not be published yet.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.

Summary

This study investigates whether optical and ultrasound biometry can reliably measure the eye's structures in people whose eyes have been filled with silicone oil after retinal detachment surgery. One hundred participants will have their eyes measured before and one month after surgery. The goal is to see if these standard tools still give accurate readings for lens power and eye length when silicone oil is present.

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 reliable, these measurement methods could help doctors choose the right lens power for cataract surgery in silicone-filled eyes.
What could go wrong
This is a small, early-stage reliability study, not a treatment trial. The measurements may prove inconsistent or not generalizable to all patients.

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