A pterygium is a benign winged-shaped growth of tissue that can expand over the cornea (the clear front window to the eye). It may remain small and not require any treatment or may grow large enough to interfere with vision. Growth usually occurs slowly, over many years, but can also have periods of rapid growth. A pterygium most commonly grows from the nasal corner of the eye.
How it is surgically removed?
Surgery is minimally invasive and takes roughly 20-30 minutes. The pterygium is first carefully peeled, then a tissue graft is harvested from beneath your upper eyelid and placed over the removal site to reduce the chance of recurrence. The graft is usually secured with tissue glue and rarely needs sutures. The site where the tissue is harvested heals on its own.
