  • The pterygium along with some associated conjunctiva tissue will be removed by the doctor.
  • The pterygium will be replaced with a graft of associated membrane tissue once it is removed to prevent recurrent pterygium growths.
  • Sutures or fibrin glue will be used by the doctor to secure the conjunctiva tissue graft in its place, once the pterygium is removed.
  • The possibility of recurring pterygia will be reduced by this procedure.
  • Dissolvable sutures can cause more discomfort postsurgery, and the recovery time can be extended for several weeks.
  • Inflammation and discomfort can be reduced while the recovery time can be reduced to half using fibrin glue, compared to using sutures.
  • Fibrin glue may carry the risk of transmitting viral infections and diseases as it is a blood derived product.
  • Fibrin glue is also more expensive than sutures.
  • Bare sclera technique to remove pterygia from the eye is another option, though it carries an increased risk of pterygium recurrence with it.
  • The pterygium tissue will be removed without replacing it with a tissue graft which leaves the underlying white of the eye exposed to heal on its own.
