Which eye surgery better restores clear vision after pterygium?
NCT ID NCT07742995
First seen Aug 03, 2026 · Last updated Aug 04, 2026 · Updated 1 time
Summary
This trial compares two surgical techniques for removing a pterygium, a fleshy growth on the eye's surface that can distort vision. Researchers are testing whether using a piece of the patient's own conjunctiva (the clear tissue covering the eye) or a preserved amniotic membrane better restores the eye's natural shape and improves vision. Adults with a primary nasal pterygium that extends onto the cornea may participate. The study measures changes in corneal astigmatism and visual acuity over 12 months 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
- Surgical procedure: either conjunctival autograft or amniotic membrane transplantation after pterygium removal
- What this could lead to
- If one technique proves better, it could become the preferred surgery for pterygium, helping more people regain clearer vision and a more regular corneal shape.
- What could go wrong
- This is a single trial with 78 participants, so results may not apply to everyone. As with any eye surgery, there are risks like infection, inflammation, or the pterygium returning.
