Nanjing Dongda Hospital femtosecond: How high is the success rate of femtosecond surgery?
Nanjing Dongda Hospital, as a well-known comprehensive hospital, is famous for its high-level medical equipment and professional medical care team. In recent years, Nanjing Dongda Hospital has introduced femtosecond laser technology, which has a significant effect on myopia patients. This article will elaborate on the principle, operation process, postoperative effect and success rate of femtosecond surgery in detail.
Principle:
Femtosecond surgery is a method of correcting myopia by laser cutting the cornea to change its curvature. Compared with traditional laser surgery, femtosecond surgery uses femtosecond lasers, which generate less heat when acting on the cornea, thus reducing the risk of tissue burning and improving the safety of surgery. In addition, the femtosecond laser also has the characteristics of high precision and high stability, which can complete the cutting in a very short time, reducing the operation time and improving the operation efficiency.
Femtosecond surgery requires accurate calculation and planning. Doctors will determine the depth and location of the cutting according to the patient's myopia, corneal curvature and other factors. During surgery, the patient will be asked to look at a fixed target, and the femtosecond laser will cut according to the preset data to correct the corneal curvature. The whole process does not require surgery, and patients can generally recover their vision immediately after surgery.
Operation process:
The operation process of femtosecond surgery is mainly divided into three parts: preoperative preparation, surgical operation and postoperative nursing. In the preoperative preparation stage, the doctor will conduct a detailed examination of the patient's eyes to assess the feasibility and risk factors of the operation. Patients need to follow the doctor's instructions for relevant preparations, such as stopping contact lenses, maintaining eye hygiene, etc.
During operation, the patient is usually required to lie on the operating table, and the doctor will give local anesthesia. Next, doctors will use femtosecond lasers for laser cutting to correct corneal curvature. The whole procedure usually takes only a few minutes, and the patient can leave the operating room soon.
Postoperative care is an important part after surgery, and doctors will guide and check patients after surgery. Patients need to comply with the doctor's requirements, use eyedrops and care for the eyes on time to avoid external irritation and friction. Generally, patients can resume normal life and work in a short time.
Postoperative effect:
After femtosecond surgery, many patients can obviously feel the improvement of vision. According to the statistical data, more than 90% of patients can reach the naked eye vision of 6/6 or more (that is, the normal people can see clearly) after surgery. This means that patients no longer need to wear glasses or contact lenses and can freely carry out daily activities and sports.
The postoperative effect of femtosecond surgery is usually stable, which means that the vision improvement after surgery will be long-term. Although recurrence may occur in some cases, it is relatively rare. For patients with recurrence, doctors can treat them again according to specific conditions.
Success rate:
According to the clinical data of Nanjing Dongda Hospital, the success rate of femtosecond surgery is very high. Generally speaking, the vision of patients after surgery can be significantly improved in a short period of time, and the postoperative effect of surgery is usually stable. However, the success of the operation is not only related to the technical level of doctors, but also to the individual differences of patients. Therefore, before femtosecond surgery, doctors will conduct a detailed examination and evaluation of patients to ensure the feasibility and safety of surgery.
Summary:
The femtosecond surgery in Nanjing Dongda Hospital changes the curvature of the cornea by laser ablation to correct myopia, which has a high success rate and stable postoperative effect. The femtosecond operation is simple, the operation process is fast, and the patient recovers well after the operation. However, since human operation is involved, it is crucial for doctors to check and evaluate patients before surgery. Only by determining the feasibility and safety of surgery can the success rate of surgery be guaranteed.
Therefore, for myopia patients, if they meet the surgical conditions, femtosecond surgery is a very effective method for myopia correction. Nanjing Dongda Hospital, as a hospital with rich clinical experience and professional technology, provides safe and efficient femtosecond surgery services for patients.
