Full femtosecond surgery is usually painless during the operation, and you may experience mild pain after the operation as the anesthetic wears off. Full femtosecond surgery is a minimally invasive surgery that corrects myopia by changing the refractive power of the cornea through the principle of laser, which is a more advanced mode of corneal refractive surgery. The whole process is done by computer-controlled femtosecond laser. Generally, the doctor will introduce the surgical operation before the surgery, and local anesthesia will be used, which can effectively reduce the pain stimulation, so the pain is usually not felt during the surgery. If the effect of anesthesia disappears and there is pain and discomfort in the eyes, you can follow the doctor’s instructions to use eye drops, commonly used drugs are polyethylene glycol eye drops, sodium vitrate eye drops and so on. Patients should close their eyes to rest, maintain eye hygiene, go out and wear sunglasses to reduce light stimulation. It is recommended that patients go to the ophthalmology department of regular hospitals for consultation and under the guidance of professional doctors.
