How is the full femtosecond operation performed in Ren'ai Hospital

Full femtosecond surgery is a modern corneal refractive surgery, which has gradually attracted more and more people's attention and choice. As a real hospital, Ren'ai Hospital provides professional full femtosecond surgery and high-quality ophthalmic treatment services for patients.

Preparation before operation

Before the full femtosecond surgery, the doctor will carefully check the patient's eye conditions, including corneal morphology and curvature measurements, to determine the suitability of the surgery. At the same time, doctors will also understand the patient's medical history and personal habits, as well as the patient's expectations and needs for surgery.

After confirming the suitability of the operation, the doctor will introduce the process and risks of the operation to the patient in detail and answer the patient's questions. In order to ensure the smooth operation, patients need to follow the doctor's instructions, such as stopping wearing contact lenses.

At the same time, Ren'ai Hospital will also conduct a comprehensive preoperative examination to ensure that there are no other potential diseases in the patient's eyes, thus reducing the risk of surgery.

Detailed steps of the surgical procedure

All femtosecond surgery is to use femtosecond laser to accurately cut and adjust corneal refraction, so as to improve vision problems. The operation process can be roughly divided into the following steps:

1. Laser preparation: the patient needs to lie on the operating table, and the doctor will give the patient some anesthetic eye drops to reduce discomfort. Then, the doctor will scan the cornea through laser equipment to obtain accurate corneal images.

2. Laser cutting: doctors guide laser equipment to cut according to the patient's corneal image. Femtosecond laser can achieve high-precision cutting in nanosecond (10 to the negative 9th power second) level, which is more accurate and safe than traditional surgical methods.

3. Refractive adjustment: After the cutting, the corneal morphology will change, thus changing the diopter. The doctor will adjust according to the patient's diopter to achieve the ideal correction effect.

4. Postoperative nursing: After the operation, the doctor will give the patient necessary nursing guidance, including correct use of eye drops and avoidance of intense eye activity. Patients need to rest and recover for a specified time according to the doctor's recommendations to ensure the effect of surgery.

Advantages and late effects of surgery

Full femtosecond surgery has the following advantages over traditional surgical methods:

1. High precision: femtosecond laser can perform precise cutting within nanosecond level, reduce surgical error and improve correction effect.

2. Safe and reliable: Femtosecond laser adopts non-contact operation, which avoids the process of scraping cornea in traditional surgery and reduces the risk of infection and pain.

3. Fast vision recovery: vision recovery is fast after full femtosecond surgery, and patients can generally return to normal life and work within a few days after surgery.
