The time for myopia surgery is actually not long, if you are doing a semi-femtosecond surgery, for the surgery time, it takes about one minute to do the semi-femtosecond flap making, about two minutes for both eyes, and laser scanning for both eyes, about one minute for each eye, so the general time required for myopia surgery may be about ten minutes. In addition, there are preoperative preparations for myopia surgery. Before surgery, the anesthetic is routinely ordered, usually four times, and this takes 5-6 minutes. In addition, during the surgery there is also eye washing, which takes about five minutes, and before the surgery there is also disinfection, laying towels, debugging machines and medical care three checks and seven pairs, which also takes 3-4 minutes, and after the surgery there is also eye medication, missionary and so on, so the overall myopia surgery time, it takes about half an hour.
