About this procedure
Surgical removal of a pterygium may be considered if a conjunctival growth extends over the cornea, progresses, affects vision or causes substantial discomfort. The decision is based on a full ophthalmic examination.
What you should know
A pterygium is usually a benign surface growth rather than a typical cancerous tumour. Surgery aims both to remove tissue and reduce recurrence. The possible use of a conjunctival autograft or amniotic membrane depends on the case.
Symptoms and reasons for assessment
Symptoms can include burning, dryness, watering, a foreign-body sensation and sometimes altered corneal shape or reduced vision. A small stable pterygium without meaningful symptoms does not always require surgery.
Other possible explanations
Other surface lesions can look similar and need careful assessment. Not every red or dry eye calls for an operation, and pterygium removal must not be confused with laser treatment for short-sightedness.
How the condition is assessed
Preoperative checks may include slit-lamp examination, the borders of the growth, corneal condition, visual acuity and refraction. Previous treatment matters because recurrent disease may need a different approach.
Treatment and follow-up options
The surgeon determines the technique, local anaesthetic, postoperative care and follow-up schedule. Healing needs monitoring, and the eye should be protected as instructed. Tissue may regrow even after technically appropriate surgery.
When urgent care is needed
Severe pain, substantial discharge, sudden deterioration in vision or other unexpected worsening after surgery requires prompt medical attention rather than waiting for follow-up. Call emergency services on 103 if life is at risk.

Frequently asked questions
Can a pterygium recur after removal?
Yes. Recurrence remains possible and is considered when planning the operation and follow-up.
Can it be removed without an operation?
Lubrication and sun protection can ease irritation but do not remove established growth.
Is follow-up necessary after pterygium surgery?
Yes. The doctor needs to assess healing and monitor for complications or regrowth.
