How is the femtosecond operation performed in Lanzhou Hospital?
A hospital in Lanzhou is a professional ophthalmic hospital with advanced equipment and experienced doctors. In recent years, the hospital has introduced femtosecond laser surgery equipment to provide more advanced and convenient treatment for myopia patients. Next, we will introduce the femtosecond surgery in Lanzhou Hospital in detail from four aspects: preoperative preparation, surgical process, surgical advantages and postoperative nursing.
1、 Preparation before operation
Before undergoing the femtosecond surgery in Lanzhou Hospital, patients need to undergo a series of examinations, such as fundus examination, vision examination, corneal topography, etc. The doctor will make a comprehensive evaluation on the patient according to the examination results to determine whether it is suitable for femtosecond surgery. Before the operation, the doctor will introduce the operation process, precautions and possible risks to the patient in detail. The patient needs to sign the informed consent form before the operation.

The doctor will give the patient eyedrops to anaesthetize the eyes before the operation to ensure that the patients' eyes will not feel pain during the operation.
2、 Operation process
Femtosecond surgery in Lanzhou Hospital is a non-contact surgical method, which uses femtosecond laser to cut the cornea of patients. During the operation, doctors will accurately cut the cornea through the femtosecond laser high-speed rotating ultra-fine laser beam to remove the myopia, so as to change the curvature of the cornea, so as to achieve the effect of correcting myopia.
The whole operation process only takes a few minutes. During the operation, the patient will feel some pressure and slight tingling, but there will be no severe pain. During the operation, the doctor will use a microscope to observe the eyeball and adjust it according to the patient's corneal topography and degree.
3、 Surgical advantages
