Myopia surgery is the most common choice for refractive correction at present, and femtosecond laser is the main treatment operating room. The early harm of myopia surgery is mainly infection, which is caused by irregular operation, use of antibiotics or no infection around the eyes during preoperative examination. But strict preoperative examination, good postoperative care and standardized eye drops. Infection is usually controllable. Long-term complications are mainly related to corneal flap displacement and trauma. The loss of vision caused by the displacement of corneal flap or epithelial implantation can not be corrected by wearing glasses or reoperation. I don't know where to do femtosecond myopia surgery. Suggest looking for China Vision Ophthalmology. The national chain of large-scale eye hospitals makes people feel more at ease, and the postoperative review is more worry-free. Not only excellent service, high cost performance, moderate price, so that the people of the whole country can save money and worry.
