Full femtosecond surgery in Nanjing Military General Hospital
As a well-known military hospital, Nanjing Military General Hospital has rich experience and excellent teachers in the field of ophthalmology. As a modern surgical technique for myopia correction, full femtosecond surgery is favored by the majority of patients. This article will elaborate on the full femtosecond surgery in Nanjing Military General Hospital from four aspects: the principle of surgery, the indication of surgery, the risk of surgery and the effect of surgery.
1、 Operation principle
All femtosecond surgery is a surgical method to correct myopia through laser. The operation uses femtosecond laser to directly act on corneal tissue through focused beam. The laser forms tiny bubbles on the corneal tissue, and through the coagulation, the normal corneal curvature is shaped, thus improving the vision.
Compared with traditional laser myopia surgery, full femtosecond surgery has the advantages of faster surgery process and more accurate laser energy. At the same time, since no scalpel operation is required during the operation, the fear of patients and the risk of surgery are reduced.
2、 Surgical indications
All femtosecond surgery is suitable for myopia patients within a certain age range. Generally speaking, patients suitable for full femtosecond surgery have the following conditions:
First, between 18 and 45 years old, eye development is relatively stable.
Secondly, the correction is between - 0.5D and - 10D, and the corneal thickness meets the surgical requirements.
Finally, there are no other eye diseases or surgical contraindications, such as keratopathy, dry eye, etc.
3、 Surgical risk
Although full femtosecond surgery is a relatively safe ophthalmic surgery, there are still some risks in surgery. Patients need to fully understand and communicate with doctors before surgery. Possible surgical risks include:
First, dry eye symptoms may occur after surgery, including eye discomfort, vision loss, etc.
Secondly, problems such as halo and poor night vision may occur after surgery, and most of these conditions will gradually disappear with time.
Finally, the operation may fail, and a second operation or other treatment measures need to be taken.
4、 Surgical effect
All femtosecond surgery has significant effect in correcting myopia. After the operation, the degree of myopia of the patient was significantly reduced, and the vision was significantly improved. According to the statistics of the hospital, the vision of most patients undergoing full femtosecond surgery can reach 1.0 or higher after surgery.
In addition, the effect of full femtosecond surgery is relatively durable and stable. After surgery, after a period of repair and recovery of the cornea, the stable correction effect can last for a long time. After the operation, patients need to have regular reexamination according to the doctor's requirements, so as to find and deal with possible problems in a timely manner.
Summary
As a modern surgical technique for myopia correction, the full femtosecond surgery in Nanjing Military General Hospital uses laser to correct myopia, which has the advantages of fast operation process and accurate laser energy. Suitable surgical indications include myopia patients aged between 18 and 45 years. The surgical risks include dry eye symptoms, halos, etc., and the possibility of surgical failure exists. The operation effect is obvious and can significantly improve the patient's vision. However, patients need to be reviewed regularly after surgery and pay attention to possible problems. The full femtosecond surgery in Nanjing Military General Hospital provides a safe, fast and effective surgical option for myopia correction.
