Eye surgery showdown: which technique best prevents pterygium return?
NCT ID NCT07277426
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two surgical techniques for preventing regrowth of a pterygium, a non-cancerous eye growth. After removing the growth, surgeons will cover the area with either a rotated flap of nearby tissue or a free graft from under the eyelid. 342 patients will be randomly assigned to one method and followed for 6 months to see which better prevents recurrence.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Conjunctival rotational flap or conjunctival autograft (surgical procedures)
- What this could lead to
- If one method proves better, it could become the preferred surgery to prevent pterygium from growing back.
- What could go wrong
- This is a single trial with 342 patients, and results may not apply to everyone. Both surgeries carry standard risks like infection or recurrence.
