What are the other Names for the Procedure?
- Pterygium Removal
What is the Pterygium Excision surgical procedure?
Pterygium Excision is a procedure that improves vision through the removal of a pterygium, which are abnormal benign tissue that grow over the cornea.
What part of the Body does the Procedure involve?
A Pterygium Excision procedure involves the eye, cornea, and conjunctiva, which are membranes that cover the eye.

A Pterygium Excision is performed for the following reasons:
- To restore vision to normal

What are some Alternative Choices for the Procedure?
- Pterygium recurrence is a major problem with the use of surgery to remove this abnormal corneal growth. A few alternative techniques that follow a surgery include:
- MMC: The use of mitomycin C (MMC) drops to reduce risk of recurrence
- Beta irradiation: It works by preventing the rapid cell division that is common to a pterygium
What are the Recent Advances in the Procedure?
The surgical techniques used for Pterygium Excision have undergone advancements to reduce pterygium recurrent rates, minimize scarring, and enable a smooth corneal surface after the procedure.
What is the Cost of performing the Pterygium Excision surgical procedure?
The cost of a Pterygium Excision procedure depends on a variety of factors, such as the type of your health insurance, annual deductibles, co-pay requirements, out-of-network and in-network of your healthcare providers and healthcare facilities.
In many cases, an estimate may be provided before the procedure. The final amount depends upon the findings during the surgery/procedure and post-operative care that is necessary.
When do you need a Second Opinion, prior to the Procedure?
- It is normal for a patient to feel uncomfortable and confused by the information regarding an Pterygium Excision procedure and on what needs to be done
- If the patient needs further reassurance or a second opinion, a physician will almost always assist and also recommend another physician, if required
- Also, if the procedure involves multiple surgeries or has many alternatives, the patient may take a second opinion to understand and choose the best one. They can also choose to approach another physician independently
