Name of the Procedure:

Excision or Transposition of Pterygium without Graft

Summary

Excision or transposition of pterygium is a surgical procedure to remove or reposition a fleshy, wing-shaped growth of tissue on the white part of the eye. This growth can extend onto the cornea, potentially obstructing vision.

Purpose

The procedure addresses the presence of a pterygium, which can cause irritation, redness, and vision problems. The goals are to alleviate symptoms, prevent further growth, and improve visual function.

Indications

• Persistent eye irritation or redness
• Progressive growth of the pterygium toward the cornea, affecting vision
• Cosmetic concerns
• Recurrent pterygium after previous treatments

Preparation

• Patients might need to avoid eating or drinking for a few hours before surgery.
• Adjustment or discontinuation of certain medications as advised by the doctor.
• Pre-operative eye examination and assessment.

Procedure Description

1. Anesthetic drops are applied to numb the eye.
2. A speculum is used to keep the eye open during surgery.
3. The surgeon carefully excises the pterygium using surgical tools.
4. The area of excision is smoothed, and any necessary repositioning of tissue is done.
5. The eye is usually covered with a protective shield post-surgery.

Duration

The procedure typically takes about 30 minutes to 1 hour.

Setting

This procedure is usually performed in an outpatient surgical center or an ophthalmologist's office.
