Are you a patient with infectious keratitis (not involving the whole layer)? If medication is never effective, the condition may progress to perforation, blindness, or even removal of the eye. The most effective treatment at this point is corneal transplantation, but the scarcity of human corneal material delays the disease in many patients. In addition, many patients are still at risk of corneal perforation, blindness and even eye removal due to recurrence of the original disease after corneal transplantation, immune rejection after corneal transplantation and other reasons. At present, the technique of corneal transplantation with decellularized allogeneic corneal stroma material for the treatment of infectious keratitis, which is carried out by the keratoconus specialist of Zhongshan Eye Center of Sun Yat-sen University, has been approved by the state, and is carried out by the Eye Center of Sun Yat-sen University, Eye Hospital of Tianjin Medical University, Henan Provincial Eye Hospital, Southwest Hospital of the Third Military Medical University, Beijing University Third Hospital, Central South University Hospital, Beijing University Hospital, Beijing University Hospital, Beijing University Hospital, Beijing University Hospital, Beijing University Hospital, Beijing University Hospital. The Third Hospital of Peking University and Xiangya Hospital of Central South University are participating in a multi-center clinical study. The decellularized allogeneic corneal stromal material used in this technology has been tested and approved by the National Institute of Food Inspection and Certification, and is a corneal transplant material that meets the national standards for human tissue and organ transplants. It is a good alternative material for lamellar corneal transplantation in clinical practice. This treatment technology is a blessing for patients! It reduces the risk of corneal perforation, reduces the incidence of post-transplant rejection, and reduces the recurrence of post-operative infections in patients with infectious keratitis who have not been treated with medications and who have not had a full layer of the disease. Once a patient is eligible, he or she can schedule an appointment for surgery without a long wait, and will be followed up after surgery and scheduled in advance for a review at a specialist clinic. Patients who are successfully selected and qualified can benefit from: decellularized allogeneic corneal stroma lamellar corneal transplantation to treat this type of patient may save the eye, prevent deterioration of the disease and avoid removal of the eye. Waiver of the cost of corneal transplant materials, free examinations, and some free medications. Receive some transportation assistance.
