At the first visit the doctor listens to your concern, takes a medical history and examines you. Not everyone who comes for a consultation needs a procedure.
Treatment planning
How the plan is decided.
Treatment depends on your symptoms, the size of the growth and the examination findings.

In detail
Pterygium: what to know.
What a pterygium is
A pterygium is a harmless, fleshy, wedge-shaped growth of the clear lining of the eye (conjunctiva) onto the cornea, usually on the side nearer the nose.
- It is linked to sunlight (UV), dust, wind and hot, dry climates.
- It can cause redness, grittiness and blurred vision, or no symptoms at all. It can also change the shape of the cornea (astigmatism).
- UV-protective wraparound sunglasses and a wide-brimmed hat help protect the eyes.
When surgery is considered
- Drops can ease irritation, but only surgery removes a pterygium.
- Surgery is considered when it causes persistent symptoms, affects vision or the shape of the cornea, keeps growing, restricts eye movement, or bothers you cosmetically.
The operation
- The pterygium is removed, and the bare area is covered with a thin graft of your own conjunctiva, usually taken from under the upper eyelid.
- In a conjunctival-limbal autograft (CLAG), the graft includes tissue from the edge of the cornea, which helps act as a barrier to regrowth.
- The graft is held with tissue glue, dissolvable stitches, or both.
- Usually done under local anaesthetic as a day case.
Recovery
- The eye is padded overnight, and antibiotic and steroid drops are used afterwards.
- The eye is sore and sensitive to light for a few days and much better by about a week. Redness can take three to four weeks to fade.
- Most people take about a week off work, longer in dusty jobs. Avoid swimming until your follow-up visit.
Risks
Every operation carries some risk. Your doctor will go through the risks that apply to you before you decide.
- The pterygium can grow back, most often within the first year.
- Infection, prolonged inflammation, a faint scar on the cornea or a change in glasses prescription.
- Rarely, scarring that affects eye movement and causes double vision.
