Pterygium is a degeneration, hypertrophy, and hyperplasia of the bulbar conjunctiva and subconjunctival tissues in the lid fissure, which develops into the cornea in a triangular shape, like a wing, hence the name. It is most often seen in outdoor workers, with fishermen and farmers having the most incidences. Many people also mistake it for cataract. The disease is a common ophthalmic disease, not timely treatment, often leading to eye redness, dryness and fatigue, foreign body sensation and other discomfort, invasion of the black cornea will also lead to increased corneal astigmatism, blurred vision, irreversible corneal degeneration turbidity, is also plagued by many people’s “red eye” one of the culprits. Figure 1: Before pterygium surgery The most effective treatment for most patients is still surgery, but many patients are hesitant to get the doctor’s advice: “I heard it’s easy to have surgery.

Figure 2: First day after pterygium surgery Figure 3: One month after pterygium surgery In fact, in the past decade or so, ophthalmology has developed rapidly, and ophthalmic surgery has evolved from ordinary surgery to microscopic surgery, and the surgical treatment of pterygium has evolved from simple excision to new surgery such as excision plus corneal margin stem cell transplantation or amniotic membrane transplantation. The recurrence rate has also decreased from about 30% to 5%, and can be even lower with experienced surgeons.
