How long does the femtosecond surgery take?

The rapid development of ophthalmic surgery makes the treatment of eye diseases more safe and efficient. Among them, femtosecond Laser Assisted Surgery has been widely concerned and applied in recent years due to its high accuracy and safety. So, how long does the femtosecond surgery take to complete? The following is a detailed description of the surgical process, different surgical types, surgical robot technology and surgical experience.

Operation process

Femtosecond surgery is mainly applied to corneal surgery, such as myopia surgery, laser in situ keratomileusis (LASIK), etc. The operation process generally includes the following steps:

1. Puncture: First, use a femtosecond laser to make a incision in the front of the cornea.

2. Wound preparation: Next, the laser will use the ultra fast laser pulse to cut the thin layer of cornea to form a wound ready for surgery.

3. Exclude the cut tissue: The laser will exclude the cut tissue through the prepared channel, and prepare the correct shape and depth for the surgical wound.

The whole procedure usually takes only a few minutes.

Different types of surgery

Different types of femtosecond surgery have different needs for operation time.

1. Femtosecond LASIK surgery: This kind of surgery is usually completed within 3-5 minutes.

2. Femtosecond corneal flap surgery: This kind of surgery can be used for corneal transplantation and other treatments, and the operation time is generally about 5-10 minutes.

3. Femtosecond cataract surgery: This kind of surgery is used for cataract extraction and intraocular lens implantation, and the time is generally about 10 minutes.

Surgical robot technology

In recent years, some hospitals have begun to introduce surgical robot technology to improve the accuracy and safety of surgery. The femtosecond surgical robot can accurately execute the surgical steps through computer aided and automatic control. This technology can not only reduce the time required for surgery, but also improve the success rate of surgery and the surgical experience of patients.

In fact, it only takes a few seconds to use femtosecond surgical robot for laser correction surgery, which greatly shortens the whole surgical process and also reduces the postoperative recovery time of patients.

Surgical experience

The time required for femtosecond surgery also depends on the surgical experience and proficiency of doctors.

1. Experienced doctors can usually complete the operation more quickly and reduce the operation time.

2. A skilled doctor is more proficient in the operation of femtosecond lasers and can complete the surgical procedures more quickly.

3. At the same time, the doctor's operation speed is also related to the patient's eye condition. If the patient's cornea is too steep or other conditions are complex, the time required for surgery may be prolonged accordingly.

To sum up, the time of femtosecond surgery varies with different types of surgery, the introduction of robot technology, and the experience of doctors. In general, the safety, efficiency and accuracy of femtosecond surgery make it an important development direction of ophthalmic surgery.
