Principle and process of femtosecond laser surgery in hospital

Hospital femtosecond laser surgery is a common ophthalmic surgery, which is used to correct myopia, hyperopia, astigmatism and other eye vision problems. It uses laser technology to improve vision by high-precision cutting and changing corneal morphology.

The process of femtosecond laser surgery is mainly divided into the following steps:

1. Pre operative examination: The doctor will conduct a detailed eye examination for the patient, including corneal curvature measurement, eye structure scanning, etc., to determine the feasibility and safety of the operation.

2. Surgical preparation: patients need to prepare for a period of time before surgery, including stopping wearing contact lenses, medication, etc. On the day of surgery, the patient will be asked to wash the eyes and receive local anesthesia.

3. Laser treatment: doctors can use a device called femtosecond laser knife to accurately cut and change the shape of cornea through high-energy laser beam. This process is very fast and usually takes only a few tens of seconds.

4. Postoperative care: After the patient completes the operation, the doctor will conduct a simple examination and give corresponding nursing suggestions, including the use of eyedrops, avoiding strenuous exercise and touching the eyes.

Advantages of hospital femtosecond laser surgery

The femtosecond laser surgery in the hospital has obvious advantages over the traditional corneal ablation surgery in the following aspects:

1. High safety: Femtosecond laser surgery uses high-precision laser technology, which can accurately control the cutting depth and corneal changes; At the same time, bubbles will be generated during the operation, effectively protecting the eye tissue from damage.

2. Fast recovery: because the operation has less damage to the cornea, the patient recovers quickly after the operation, and can usually feel obvious visual improvement within a few hours. Compared with traditional surgery, patients can return to normal life and work faster.

3. Personalized treatment: Femtosecond laser surgery can be customized according to the patient's eye conditions, so the treatment effect is more accurate and stable. Doctors can make a suitable operation plan for patients according to different degrees and corneal curvature.

Applicable population of hospital femtosecond laser surgery

The femtosecond laser surgery in the hospital is suitable for people over 18 years of age, with healthy and stable corneas, and with high myopia, hyperopia and astigmatism. Specific applicable conditions include:

1. Myopia: The degree of myopia of the patient is more than 500 degrees.

2. Hyperopia: The degree of hyperopia of the patient is more than 300 degrees.

3. Astigmatism: the patient's astigmatism degree is more than 200 degrees.

Effective femtosecond laser surgery in hospital

Years of clinical practice and research have shown that femtosecond laser surgery in hospitals is a safe, effective and reliable surgical method. After surgery, the patient's vision improved significantly, and the dependence on glasses or contact lenses could be greatly reduced.

However, everyone's eye condition is different, and the surgical effect will vary from person to person. Therefore, before deciding to accept the femtosecond laser surgery in the hospital, the patient should receive a comprehensive eye examination, consult with the doctor in detail, and understand the risks and possible complications of the surgery.

Summary

Femtosecond laser surgery in hospitals can significantly improve myopia, hyperopia and astigmatism by using laser technology to cut and change corneal morphology. It has the advantages of high safety, fast recovery and personalized treatment, and is suitable for people with myopia, hyperopia and heavy astigmatism. Although the surgical effect is effective in most patients, the surgical effect may be different due to different eye conditions of each person. Therefore, before undergoing surgery, patients should consult with doctors in detail and make full preparations.
