What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

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 Results may not be published yet.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

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 tests a new surgical method for pterygium, a growth on the eye's surface. Instead of cutting the growth out completely, surgeons move it to a different spot and stitch it down, preserving healthy tissue. The goal is to see if this lowers the chance of the pterygium coming back and improves vision. The study will enroll 70 adults with primary pterygium and follow them for regrowth and visual changes.

What this could mean

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

Active substance
Conjunctival transpositional pterygium surgery
What this could lead to
If successful, this surgical technique could offer a simpler way to treat pterygium with a lower chance of regrowth and better vision outcomes.
What could go wrong
This is a small, early study with only 70 people and no comparison group, so results may not apply widely. The surgery may still lead to regrowth or other complications.
