Pterygium Surgery – Safe and Effective Treatment Methods

A pterygium is a common eye condition that can cause persistent irritation and, if left untreated, grow large enough to seriously impair your vision. Surgery is the most definitive solution to clear the growth and restore the healthy surface of your eye. Let's follow the detailed article below with Hikari to gain a comprehensive overview of pterygium surgery methods, the step-by-step procedure, and essential post-operative care tips for a fast recovery!

What is a Pterygium?

Mộng mắt (mộng thịt) là một khối u thịt màu trắng hoặc hồng nhạt xuất hiện ở khóe mắt. Tình trạng mắt bị mộng thịt khá phổ biến, nhất là ở các nước vùng nhiệt đới. Bất kỳ ai cũng có thể bị mộng mắt.
Vậy mắt bị mộng thịt có nguy hiểm không? Mộng thịt trong mắt thường lành tính. Bệnh tiến triển chậm và có thể điều trị bằng thuốc hoặc phẫu thuật. Tuy nhiên, nếu mộng thịt ở mắt tăng kích thước sẽ che một phần giác mạc. Điều này làm cản trở tầm nhìn. Nhiều người có cảm giác mắt bị kéo màn trắng mờ, lúc này còn gọi là mắt bị mây thịt. Nếu không giải quyết, thị lực bị suy giảm, gây loạn thị và các bệnh về mắt khác.

Signs and Symptoms of a Pterygium

Dấu hiệu

In its early stages, a pterygium may be small and cause little to no discomfort. However, as the tissue grows, patients often notice the following symptoms:

• Persistent redness, swelling, or localized inflammation in the affected eye.
• A constant gritty, burning, or itchy sensation, making it feel as though sand or a foreign object is trapped in the eye.
• Dry eyes caused by an uneven tear film distribution, or conversely, excessive tearing due to chronic irritation.
• Blurred, hazy, or distorted vision if the growth pulls on the cornea (inducing astigmatism) or advances over the pupil.

Causes of Pterygium

While the exact biological cause remains under study, development of a pterygium is heavily linked to prolonged environmental exposure. Major risk factors include:

• Ultraviolet (UV) Light: Long-term, unprotected exposure to solar UV radiation is the leading cause. This makes the condition highly prevalent in tropical regions and among individuals who frequently work outdoors.
• Environmental Irritants: Regular exposure to dust, wind, sand, smoke, or excessively dry climates triggers chronic surface irritation, stimulating abnormal tissue growth.
• Chronic Dry Eye: A lack of proper eye lubrication weakens the conjunctival tissue, making it more susceptible to environmental damage.

Treatment Methods for Pterygium

Medication-Based Treatment

Pterygium can be managed with medications if detected early and if it does not significantly affect visual acuity. The physician will prescribe eye drops, gels, or ointments. If symptoms such as pain or dryness are present, artificial tears may also be recommended. If the pterygium grows slowly and does not obstruct the visual axis, surgery is not necessary, and follow-up every 6–12 months is advised.

Surgical Treatment

Vậy có nên cắt mộng mắt không và khi nào cần mổ mộng mắt? Mộng thịt được chỉ định cắt bỏ khi tốc độ phát triển nhanh. Khối u thịt bắt đầu lan đến trung tâm giác mạc và gây các vấn đề khó chịu cho mắt. Phẫu thuật mộng thịt khá đơn giản và thời gian xử lý nhanh chóng.
Sau khi tiến hành thăm khám, bác sĩ sẽ tư vấn cho bệnh nhân hướng điều trị. Phương pháp thường được dùng là xử lý khối u thịt, ghép kết mạc tự thân kết hợp thuốc chống phân bào. Nếu chỉ áp dụng cách phẫu thuật cắt mộng thịt truyền thống, tỷ lệ tái phát rất cao. Bên cạnh đó thị lực cũng hồi phục chậm và đi kèm các biến chứng đau rát, kích ứng sưng đỏ.
Ngày nay, phẫu thuật bóc mộng thịt ngày càng tiến bộ và cho hiệu quả cao như: ghép mộng tự thân, ghép màng ối, ghép tế bào mầm,…Bạn sẽ không còn băn khoăn mổ bóc mộng mắt có nguy hiểm không nữa. Bởi các phương pháp trên đều có độ an toàn cao và tỷ lệ tái phát thấp.

Post-Operative Care Following Pterygium Excision

Although pterygium excision is a minor surgical procedure, improper post-operative care can lead to significant complications. Please observe the following guidelines:

• Change dressings regularly according to your physician's instructions: avoid applying the dressing too tightly, and maintain proper hygiene and cleaning technique.
• Instill eye drops at the prescribed times; do not discontinue or self-adjust the dosage.
• Attend all scheduled follow-up appointments; if any abnormality occurs, notify your physician immediately or proceed to the nearest medical facility.
• Avoid exposing the eye to soap or water after pterygium surgery.
• Avoid falls, blunt trauma, and activities that may cause injury to the ocular region.
• Avoid overexertion, prolonged reading, or excessive exposure to screens (television, mobile phones).
• Maintain a nutritious diet with adequate intake of vitamins and dietary fiber.
• Ensure adequate rest and sleep to support overall health and expedite recovery.
  Proper wound care will facilitate faster visual recovery and help prevent unwanted complications, including infection.

Preventive Measures for Pterygium

To prevent the development of pterygium or its recurrence, the following simple measures are recommended:

• Wear protective eyewear and sunglasses when outdoors. Adequate eye protection significantly reduces the risk of pterygium and other ocular conditions.
• Schedule and attend regular eye examinations.
• Schedule and attend regular eye examinations.
• For patients currently under observation for pterygium or who have undergone pterygium excision, strictly adhere to the prescribed medication regimen.
• Supplement the diet with foods beneficial to ocular health and those that support immune function.
