☆ A new breakthrough in the surgical treatment of pterygium Xiamen Eye Center is the first in China to carry out the application of bio-gel for pterygium excision. The advantages compared with traditional pterygium excision are: significantly shorter operation time, improved postoperative suture-induced discomfort and pain, reduced postoperative recurrence rate compared with traditional pterygium excision, and easy, safe and effective surgical method.

The intact corneal rim is the barrier that prevents the conjunctiva from growing towards the cornea. Once the rim stem cells are defective or insufficient in number, this barrier is destroyed and the proliferating conjunctival fibroblasts can easily grow towards the cornea to form a pterygium. The fundamental solution to the recurrence of pterygium is to reconstruct the corneal epithelium using a tissue graft with limbal stem cells. Autologous conjunctival transplantation with corneal limbal stem cells provides healthy stem cells to the damaged corneal limbus, accelerating corneal epithelial repair and preventing recurrence of pterygium and complications. What are the special groups to be aware of for pterygium surgery? Patients who have surgery for aesthetic reasons, such as actors and teachers, should be aware that conjunctival congestion usually subsides in 3-4 weeks after pterygium surgery, during which time it can still affect aesthetics, life and work. For professions with high vision requirements such as crew members, drivers and pilots, it is important to schedule at least 3 weeks of rest before surgery to avoid post-operative fluctuations in vision due to unstable tear film.
