Changsha hospital femtosecond surgery: how to treat myopia?
Myopia is a common eye problem, and many people are troubled by it. However, with the development of medical technology, femtosecond laser surgery has become an effective method to correct myopia. Next, we will elaborate on the femtosecond surgery in Changsha Hospital from four aspects.
1、 Operation principle and process
Femtosecond laser surgery is one of the advanced technologies for the treatment of myopia. It changes the refraction of the eyeball by cutting corneal tissue with laser, so as to correct myopia. The operation process is divided into the following steps:
1. Femtosecond laser cutting: doctors use femtosecond laser to cut a thin slice on the cornea, which is called "transposition flap".
2. Corneal diopter change: By adjusting the laser parameters, doctors can cut a specific shape on the transposed flap to change the ocular diopter.
3. Flap reposition: After the corneal diopter changes, the doctor will reposition the transposed flap and wait for its self healing.
The whole operation process usually takes only a few minutes, and it recovers quickly after the operation with almost no pain.
2、 Surgical advantages
The femtosecond surgery in Changsha Hospital has the following advantages:
1. High safety: Femtosecond laser surgery uses non-contact cutting, which avoids the possible infection and infection transmission risk when traditional surgery cuts on the cornea.
2. Stable effect: the vision recovers quickly and the effect is stable after operation. Most patients can feel a significant improvement in vision within a few days after surgery.
3. Short recovery period: the operation process is relatively short, and the postoperative recovery is rapid. Generally speaking, patients can resume normal daily life within 3-7 days.
4. Individualized treatment: Femtosecond laser surgery can provide personalized treatment according to the specific situation of patients to better meet the needs of patients.
3、 Operation indications and contraindications
Femtosecond laser surgery is applicable to the following situations:
1. Moderate myopia: surgery is generally applicable to patients with myopia between -1.00D and -10.00D.
2. Age appropriate: Generally speaking, the patient should be over 18 years old, and the eyeball is mature and stable.
3. No other eye diseases: comprehensive eye examination is required before surgery to ensure that the patient has no other eye diseases.
The contraindications of femtosecond laser surgery mainly include:
1. Pregnant or lactating women: Femtosecond laser surgery may cause adverse effects on the fetus or baby.
2. Severe dry eye patients: The operation will further aggravate dry eye symptoms.
3. Patients with other serious eye diseases: surgery may affect the treatment effect of the disease.
4、 Precautions after operation
After femtosecond laser surgery, patients should pay attention to the following points:
1. Avoid eye collision: Since the eyes are sensitive after surgery, avoid eye collision and intense exercise to prevent corneal infection.
2. Pay attention to eye hygiene: pay attention to eye hygiene after surgery, and avoid rubbing or touching eyes with hands to prevent infection.
3. Regular return visit: regular return visit is required after the operation, and the doctor will conduct further inspection and guidance according to the patient's condition.
summary
The femtosecond surgery in Changsha Hospital is an advanced technology for treating myopia. It has the characteristics of clear surgical principle, obvious advantages, clear indications and contraindications, and clear postoperative precautions. For patients who need to correct myopia, femtosecond laser surgery is a choice worth considering.
