Most pterygium cause no problems and don't need treatment. However, it is important to have this monitored. If the growth continues and begins to affect your vision or cause ongoing eye discomfort, you may need treatment.
Your eye care provider may recommend artificial tears or eye drops to reduce your discomfort. If the pterygium is inflamed, They may also prescribe non-steroidal anti-inflammatory drops (eg, Acular, Voltaren Optha).
Your eye care provider may recommend surgery if your vision is affected or if medicines have not given you enough relief.
The surgery involves removing the pterygium from the sclera (white) and cornea (outer lens) of your eye. The area is then covered with a small graft of your own healthy conjunctiva (surface tissue).
This is usually performed under local anaesthetic, and takes half an hour. A pad is placed over the eye and you will need transport home.
You shouldn't feel any pain during the procedure, but it's normal for your eyes to feel scratchy for a few days afterwards, and you will need a day or two off work.
You will need to use eye drops for about a month after the surgery to help your eye heal. After surgery, take extra care with wearing protective glasses and a hat with a brim to prevent it returning. The recurrence rate for this procedure is 5%.
Your glasses will need to be upgraded following surgery.
