Background: One of the frequent ocular disorders affecting people in their middle and advanced years of age is pterygium. It is a benign, proliferative disorder of the conjunctiva and subconjunctival tissue that has the potential to impair vision. Clinical examination can quickly diagnose and stage it. Sunlight exposure is believed to be the most significant element in the development of pterygium. Dry eyes, smoking, prolonged outdoor activity, low socioeconomic position, and high altitudes are additional risk factors. If it grows onto the cornea's centre, a major problem is the obliteration of the visual axis. Another reason for impaired vision is the development of irregular astigmatism brought on by flattening of the cornea in the horizontal meridian.
