Ocular pterygium is a growth of the conjunctiva that forms a pterygium and extends into the cornea, or “black eye”, which is commonly referred to as pterygium hyperplasia or pterygia. Pterygium surgery is usually considered only when the pterygium has invaded the cornea by about 2-3 mm and has a clear tendency to progress. The cost of surgery is around$3,000-4,000 per eye and may be increased by about$1,000-2,000 for amniotic membrane coverage or stem cell transplantation. The results of pterygium surgery are good, and with stem cell transplantation, the probability of recurrence can be reduced, and damage to the cornea can be reduced. Postoperative application of nutritional angle medications and antibacterial medications can also promote corneal growth, reduce pain and promote healing. Overall, the results are good with stem cell transplantation.
