It arises from subconjunctival tissue and may extend over the cornea thus disturbing the vision. It is seen more frequently in tropical and subtropical areas where exposure to UV sunlight is high. Pterygium causes cosmetic imbalance of the ocular surface with chronic hyperemia and frequent discomfort in the affected patients; it is frequently progressive toward the cornea being potentially the source of optical changes in the anterior corneal surface, such as progressive astigmatism and higher order aberrations. For all these reasons, it frequently requires surgical excision. The main aim of pterygium surgery is to eliminate it, prevent its recurrence, and restore the ocular surface integrity and cosmetics. In our chapter, we are going to discuss different techniques for pterygium management.
