How does the femtosecond surgery in Zhongshan Hospital treat myopia?
Myopia is one of the common vision problems of modern people, which brings great trouble to people's life and work. In recent years, more and more people choose surgery to treat myopia. The femtosecond surgery in Zhongshan Hospital is an effective and safe treatment for myopia. By using femtosecond laser technology, it can change the corneal curvature of the eye, thus achieving the purpose of correcting myopia.
Operation principle
Femtosecond surgery is the use of laser technology to change the curvature of the cornea, thereby correcting myopia. During surgery, doctors will use femtosecond lasers to cut the surface of the cornea, and then reshape the cornea with lasers. In this way, the curvature of the cornea can be changed so that it can focus the light correctly, thus achieving the effect of correcting myopia.
The advantage of femtosecond surgery is its high accuracy and safety. Laser technology can accurately cut the cornea, avoiding the possible errors in traditional surgery. At the same time, femtosecond surgery has no mechanical cutting, which reduces the damage to the cornea caused by surgery. Therefore, femtosecond surgery can better protect patients' eye health.
Operation process
Femtosecond surgery is a minimally invasive surgery, usually performed under local anesthesia. The operation process is divided into the following steps:
1. Determine the depth and area of corneal cutting before surgery by measuring the curvature of the cornea.
2. Doctors will use femtosecond lasers to cut the surface of the cornea, which usually takes only a few seconds.
3. After cutting, the doctor will use the laser to reshape the cornea, and determine the depth and shape of the reshaping according to the patient's myopia and corneal conditions.
4. After the operation, the doctor will give some care and guidance to the patient, including eyedrops, avoiding eye rubs, etc.
Postoperative care and effect
Postoperative care should be paid attention to after femtosecond surgery. Patients need to follow the doctor's instructions, such as dropping eyedrops and avoiding rubbing eyes, to protect their eyes. At the same time, patients need to avoid strenuous exercise and exposure to strong light to avoid eye irritation. Generally speaking, the recovery period after surgery is 1-2 weeks, and the patient needs regular reexamination to ensure that the surgical effect and corneal healing are good.
The effect of femtosecond surgery on myopia is usually significant. Many patients can feel the improvement of vision after surgery. After surgery, patients can significantly reduce or no longer need to wear glasses. At the same time, femtosecond surgery can correct the degree stability of myopia and make the visual effect more lasting.
summary
The femtosecond surgery in Zhongshan Hospital is a safe and effective treatment for myopia. Femtosecond laser technology can accurately change the curvature of the cornea and correct myopia. The operation process is minimally invasive and accurate, the postoperative recovery period is short, and the effect is significant. However, the patient's eye health must be ensured before surgery to identify whether it is suitable for femtosecond surgery. If you have myopia, you can consider consulting experts from Zhongshan Hospital to learn more about femtosecond surgery and its application.
