What is the primary goal of a pterygium excision?

The primary goal of a pterygium excision is indeed to remove abnormal conjunctival tissue. A pterygium is characterized by the growth of abnormal tissue that can extend over the cornea and can cause irritation, redness, and potential visual impairment if left untreated. By excising this tissue, the procedure aims to alleviate symptoms, prevent further corneal involvement, and decrease the risk of recurrence, which is a common concern with pterygium.

While improving visual acuity can be a secondary benefit of the excision if the pterygium is obstructing vision, the primary focus is on the removal of the abnormal tissue itself. Addressing eye muscle imbalance and enhancing corneal health are not direct goals of this specific surgical intervention, making them less relevant in this context.
