TL;DR: Blue Fin Vision® offers pterygium surgery in Chelmsford at Phoenix Hospital Chelmsford, Essex Healthcare Park, West Hanningfield Road, Chelmsford, CM2 8HN. We use excision with conjunctival autograft: the growth is removed and the area covered with a thin graft of your own healthy conjunctiva, the membrane covering the white of the eye, taken from under the upper eyelid. It is the technique best supported by evidence for keeping a pterygium from coming back.
The aim of pterygium surgery is not only to remove the growth, but to reduce the chance of it returning.
What Is a Pterygium?
A pterygium is a fleshy, wedge-shaped growth that spreads from the white of the eye onto the cornea, the clear front surface of the eye, usually from the side nearest the nose.
It is linked to ultraviolet light: light entering from the side of the eye may be focused onto that inner corner. ¹ Pterygium is more common in sunnier climates and in people who spend long periods outdoors, ² so many patients in Essex have worked outdoors or lived abroad.
A pterygium: a fleshy growth extending from the white of the eye across the edge of the cornea.
When Is Surgery for Pterygium Recommended?
Surgery is usually advised when a pterygium:
- Is growing towards the centre of the cornea.
- Is causing astigmatism, an uneven curvature that can blur or distort vision, or other blurred vision.
- Is persistently red, gritty or uncomfortable.
- Interferes with contact lenses or bothers you cosmetically.
Removing it before it reaches the line of sight gives the cornea the best chance of recovering a smooth, regular surface.
Why the Graft Matters
Recurrence, meaning the growth returning, is the main risk after pterygium surgery. Removing the growth and leaving the white of the eye bare allows it to return more often.
A Cochrane review found that covering the area with a conjunctival autograft lowered the risk of recurrence compared with amniotic membrane grafting, particularly for pterygia that had already come back once. ³ Pterygia is the plural of pterygium. An amniotic membrane graft uses donated tissue from the membrane surrounding a baby during pregnancy.
A report by the American Academy of Ophthalmology found that pterygium surgery with conjunctival autograft reduces recurrence compared with bare-sclera excision, where the growth is removed without covering the exposed white surface with a graft. ⁴
Your Recovery
- First two days: the small area where the pterygium was lifted from the cornea heals, usually within 24 to 48 hours; grittiness and watering are expected.
- First week: most people return to work within three to seven days.
- Two to six weeks: redness gradually fades.
- Three to six months: the eye fully settles.
Recurrence is more likely in younger patients, whose healing response is more vigorous, and sun protection afterwards helps.
A pinguecula, a small, raised patch on the white of the eye, often coexists with pterygium. ⁵ Both can be assessed at the same visit.
