Description of the disease: In December 2014, I found something white and flesh-like in my father’s eye, I thought it was a cataract, no discomfort, told him to check it and he didn’t go. 30 March 2015, I heard him say his eye was a little itchy and a little painful. 4.3 in Xiangxiang City Hospital of Traditional Chinese Medicine to see the doctor, anesthesia to pick out three sand, the doctor requested immediate hospitalization, 4.4 surgery. I would like to ask the doctor if there is a good way to keep the pterygium from recurring after surgery. Qin Rui, Ophthalmology, Eye Hospital, Chinese Academy of Traditional Chinese Medicine, replied: Hello! The surgical methods of pterygium include simple excision, pterygium transposition and burial, pterygium excision combined with autologous corneal conjunctival tissue transplantation, etc. The first one is simple but has a high recurrence rate and is rarely used now, the second one is simple and has a low recurrence rate, but will leave red blood in the corners of the eyes for a long time, most people now recommend the last method, which generally has a recurrence rate of less than 5% and is safe and effective. Patient Question: Hello doctor, what is the approximate cost of the third surgical method? Is the risk high? Qin Rui, Ophthalmology Department, Chinese Academy of Traditional Chinese Medicine, replied: The total cost of surgery is more than 1,000 yuan, but preliminary laboratory tests are also needed. If the pterygium is more than half the size of the black eye, you will need to add an amniotic membrane graft for recovery, which adds about$900. This surgery is an external eye surgery, the risk is not high, the main thing is to pay attention to the post-operative eye drops on time, keep hygiene and clean, to reduce the recurrence rate.
