Pterygium Surgery

What is Pterygium Surgery?

Pterygium surgery is a procedure to remove a pterygium, a benign, wedge-shaped growth of tissue on the conjunctiva that extends onto the cornea. It is often caused by prolonged exposure to UV light, wind, and dust. While mild cases may be managed with lubricating eye drops, surgery is recommended when the pterygium causes discomfort, vision impairment, or cosmetic concerns.

How is Pterygium Surgery Performed?

1. Preparation: The eye is numbed with anesthetic drops.
2. Removal: The surgeon excises the pterygium from the cornea and conjunctiva.
3. Grafting: To prevent recurrence, a conjunctival autograft (healthy tissue from another part of the eye) is placed over the affected area using sutures or fibrin glue.
4. Healing: The eye is covered with a bandage contact lens for protection.

The procedure takes about 30-45 minutes and is performed on an outpatient basis.

What to Expect During the Procedure

• Pterygium surgery is painless due to local anesthesia.
• Mild discomfort, redness, and irritation are common during recovery.
• Complete healing takes a few weeks, with vision improving gradually.
• Medicated eye drops are prescribed to prevent infection and reduce inflammation.

The Importance of Pterygium Surgery in Eye Health

Pterygium surgery restores clear vision, reduces discomfort, and improves cosmetic appearance. Removing the growth prevents further corneal damage and potential vision loss. The use of a conjunctival graft significantly lowers the risk of recurrence.
