About Pterygium Excision with Conjunctival Limbal Autograft
Pterygium Excision with Conjunctival Limbal Autograft is an advanced surgical procedure performed to remove a pterygium — a non-cancerous growth of tissue on the white part of the eye that may extend onto the cornea and affect vision. This condition can cause redness, irritation, dryness, and blurred vision if left untreated.
The limbal autograft technique significantly reduces the risk of recurrence by transplanting healthy conjunctival tissue along with limbal stem cells from the patient’s own eye to the affected area. This modern approach ensures better cosmetic results, improved healing, and long-term stability.
Procedure
The procedure begins with a thorough eye examination to assess the size, location, and severity of the pterygium. Surgery is typically performed under local anesthesia to ensure patient comfort.
During the procedure, the abnormal tissue is carefully removed from the cornea and sclera. A thin layer of healthy conjunctival tissue, including limbal stem cells, is then harvested from another part of the same eye and securely placed over the exposed area using sutures or tissue adhesive.
This technique promotes natural healing, reduces inflammation, and lowers the chances of recurrence. Post-operative care includes prescribed eye drops and scheduled follow-up visits to monitor recovery. Most patients experience significant relief from irritation and improved cosmetic appearance within a short period.
