PTERYGIUM EXCISION
Pterygium excision is a surgical service that removes a fleshy, wing-shaped growth on the white part of the eye that extends toward the cornea. This growth often relates to long-term sun, wind, and dust exposure. As it enlarges, it can cause redness, irritation, blurred vision, and induced astigmatism. Therefore, timely removal helps restore comfort and protect visual quality.
WHAT THIS SERVICE TREATS
A pterygium is a benign surface growth of conjunctival tissue that can slowly advance onto the cornea. At first, symptoms may be mild. However, progression can lead to chronic irritation and visual distortion. Surgical excision removes the abnormal tissue and clears the corneal surface. In addition, modern techniques reduce recurrence risk by using tissue grafts or adjunctive therapy.
WHEN SURGERY IS RECOMMENDED
Your ophthalmologist may advise pterygium excision when symptoms or structural effects become significant. For example, surgery is considered in the following situations.
1. Reduced vision from corneal involvement or astigmatism
2. Persistent redness and irritation despite medical care
3. Documented growth toward the visual axis
4. Recurrent inflammation
5. Cosmetic concern with active progression
HOW THE PROCEDURE IS PERFORMED
The surgery is usually performed under local anesthesia in a sterile setting. First, the abnormal tissue is carefully removed from the cornea and sclera. Next, a conjunctival autograft or similar surface graft is placed to cover the area. This step lowers recurrence rates and improves healing. The surgeon then secures the graft with fine sutures or tissue adhesive. Most procedures finish within one hour.
RECOVERY AND AFTERCARE
After surgery, patients use prescribed eye drops to control inflammation and prevent infection. Mild discomfort, redness, and foreign body sensation may occur at first. However, these symptoms usually improve over days to weeks. Protective measures such as sunglasses and UV avoidance support better outcomes. Follow-up visits remain important to monitor healing and detect early recurrence.
WHY EARLY MANAGEMENT MATTERS
Progressive pterygium can distort the cornea and affect vision. Early surgical management, when indicated, reduces long-term surface damage. Moreover, graft techniques improve stability and lower repeat growth risk. As a result, patients gain better comfort and more stable visual quality.
