Best Doctor List Near You for Excision Of Pterygium in Chiguayante

Excision of pterygium is a surgical procedure aimed at removing a pterygium, which is a benign, abnormal growth of conjunctival tissue extending onto the cornea. This growth often resembles a triangular or wedge-shaped flap of tissue and can cause a range of issues including discomfort, visual disturbances, and cosmetic concerns. Pterygia are typically caused by chronic exposure to environmental irritants such as ultraviolet (UV) light, dust, and wind. Individuals who spend a lot of time outdoors, especially in sunny or windy conditions, are at higher risk. Genetic factors may also play a role in predisposition to pterygium development. Symptoms that may prompt the need for excision include the presence of a visible growth on the eye, persistent redness, irritation, itching, and a sensation of something being in the eye. As the pterygium grows, it can distort the cornea, leading to blurred vision or decreased visual acuity. The excision procedure involves removing the pterygium tissue from the cornea and conjunctiva, often with the addition of a conjunctival autograft to reduce the risk of recurrence. Local anesthesia is used to numb the area, and the growth is carefully excised, sometimes requiring the placement of a graft to cover the exposed area and promote proper healing. The procedure is typically followed by the application of protective dressings or shields. Complications from pterygium excision can include infection, bleeding, scarring, and potential recurrence of the pterygium. Dryness and discomfort are also possible during the healing process. To minimize these risks, patients are given specific aftercare instructions, which usually include the use of prescribed eye drops or ointments, avoiding direct sunlight, and attending regular follow-up visits to ensure proper healing and address any issues that may arise. The procedure is effective in alleviating symptoms, improving vision, and enhancing cosmetic appearance, leading to overall better ocular health.
