Pterygium surgery with conjunctival autograft

What is pterygium surgery with conjunctival autograft?

Pterygium surgery with conjunctival autograft consists of resection of the pterygium by an expert ophthalmologist and subsequent grafting of the patient’s own conjunctiva in the place where the removal of the pterygium is performed, to re-establish the conjunctival layer of the area.

In which cases is it done?

Pterygium surgery with conjunctival autograft is performed when the pterygium increases in size and causes discomfort to the patient, such as astigmatism, when pulling on the cornea or vision loss due to occupation of the pupillary zone.

Previous exams

A complete ophthalmological examination is necessary prior to surgery.

Postoperative

The intervention is performed under local anaesthesia, with the patient awake. The pterygium is removed and a portion of the conjunctiva is autografted. After surgery, a patch should be placed on the patient, which will be removed in 24 hours.

The complete recovery of the patient occurs in a few weeks.

Risks

Complications such as infections, loss of corneal transparency, foreign body granuloma, hypertrophic scar… Are rare but can occur. In addition, 10% of highly evolved pterygium recur after the operation. In addition, 10% of highly evolved pterygium recur after the operation.
