Pterygium, often referred to as “surfer’s eye,” is an abnormal growth of the conjunctiva, the thin, transparent membrane covering the white part of the eye (sclera). This growth can extend onto the cornea, the transparent surface of the eye essential for clear vision, affecting visual quality.
When is Pterygium Surgery Recommended?
Pterygium surgery (with conjunctival autograft) is considered when the pterygium:
- Significantly affects vision.
- Causes persistent eye irritation, such as itching, redness, or a sandy sensation.
- Does not respond to topical treatments like lubricating eye drops or anti-inflammatory medications.
The primary objective of pterygium surgery is to remove the abnormal conjunctival growth and prevent its recurrence. Additionally, the surgery aims to restore the ocular surface to its normal state and enhance the patient’s visual quality.
Procedure for Pterygium Surgery
Pterygium surgery (with conjunctival autograft) is performed under local anesthesia, allowing the patient to remain awake but without feeling pain in the surgical area. The procedure generally includes the following steps:
- Preparation: Once the anesthesia takes effect, the surgeon carefully dissects the pterygium from the surface of the cornea and sclera, ensuring that surrounding ocular tissues are not damaged.
- Preparation of the Site: The area where the conjunctival autograft will be placed is prepared by removing any remnants of the pterygium and smoothing the surface.
- Graft Placement: A small piece of healthy conjunctiva is taken from another part of the patient’s eye and placed over the prepared conjunctival bed.
- Suturing: Fine sutures are then used to secure the conjunctival autograft in place, ensuring proper adhesion to the ocular surface.
Post-Surgery Recovery
After the surgery, patients may experience temporary discomfort such as itching, irritation, or blurred vision. Most patients can return home on the same day of the procedure. Complete recovery time can vary from 1 to 2 weeks, depending on the complexity of the case and the patient’s response to treatment.
Effectiveness of Pterygium Surgery
Pterygium surgery is an effective procedure for removing abnormal conjunctival growth and preventing its recurrence. In most cases, the results are long-lasting, and patients experience significant improvements in their vision and ocular health.
