A pterygium is a common eye condition where a pink, fleshy growth develops on the white part of the eye. While often harmless, it can sometimes grow large enough to affect vision or cause discomfort. When this happens, pterygium eye surgery may be recommended.
This article explains everything you need to know about pterygium surgery – what it is, when it’s needed, how it’s performed, and what to expect during recovery. Whether you’ve been diagnosed with a pterygium or are just curious about the procedure, this guide will give you clear, helpful information.
Understanding Pterygium
What Is a Pterygium?
A pterygium (pronounced “teh-RIJ-ee-um”) is a benign growth of conjunctival tissue that forms on the eye’s surface. It often appears as a triangular-shaped, pinkish bump near the inner corner of the eye.
Common Features:
- Triangular-shaped growth
- Usually appears on the side closest to the nose
- May be red, pink, or flesh-colored
- Often occurs in both eyes
Causes and Risk Factors
While the exact cause isn’t known, these factors increase risk:
UV exposure: Frequent sun exposure without protection
Dry eyes: Chronic irritation from dust or wind
Genetics: More common in people with family history
When Is Surgery Needed?
Signs You Might Need Surgery
- The growth reaches your pupil and affects vision
- Persistent redness and irritation
- Frequent inflammation that doesn’t improve with eye drops
- Cosmetic concerns about appearance
Non-Surgical Treatments First
Doctors usually recommend trying these before surgery:
- Artificial tears for lubrication
- Steroid eye drops to reduce inflammation
- Wearing UV-protective sunglasses
The Pterygium Surgery Procedure
Preparing for Surgery
Eye examination: Detailed check of the pterygium
Medical history review: Discuss medications and allergies
Pre-op instructions: May include stopping certain medications

Anesthesia: Local anesthesia with numbing drops
Procedure steps:
- Removal of the pterygium tissue
- Graft placement (often using conjunctival tissue)

Surgical Techniques
Bare sclera technique: Simple removal (higher recurrence risk)
Conjunctival autograft: Uses tissue from another part of eye (lower recurrence)
Amniotic membrane graft: For complex cases

First week:
