Conjunctival autograft is a surgical procedure used to treat conditions like pterygium, in which healthy tissue from the patient's own conjunctiva is transplanted to cover areas of the eye where tissue has been removed or damaged. This technique is often used in the treatment of pterygium to prevent recurrence and promote healing. During the procedure, a small section of healthy conjunctival tissue is taken from the eye and grafted onto the affected area.

Conjunctival autografting is a highly effective treatment that reduces the risk of pterygium regrowth and helps restore the normal surface of the eye. The use of the patient’s own tissue also reduces the risk of rejection.
