By @laser_eye_center_of_miami - Beautiful result minutes after topical pterygium excision surgery with amniotic membrane transplantation and Mitomycin C People with pterygium have a triangular-shaped fleshy tissue that grows onto the cornea usually from the nasal side of the eye. It is a noncancerous lesion, usually not a serious condition that thought to be due to environmental factors such as ultraviolet light, chronic dryness and exposure to wind and dust. Surgical excision, with or without conjunctival grafting (for reducing recurrence) is indicated if the pterygium progresses towards the center of the cornea or for cosmetic reasons. During the surgery the pterygium is removed and the patient's own conjunctiva is either glued or stitched to the area in order to fill the empty space created by the removal of the pterygium.
