With semifemtosecond laser surgery, a lift-off flap is first created using a femtosecond laser device, and then the excimer laser is used to make cuts to the cornea, usually in an ablative fashion. Semi-femtosecond laser surgery has a large incision because the flap is created, but less material is removed and the wound is shallow, but semi-femtosecond laser surgery allows for personalized flap making, a more uniform and thinner flap, and better predictability, which can reduce the risk of surgery as well as reduce complications. The entire procedure takes about 20 minutes and is painless due to the anesthetic. In current clinical practice, full femtosecond laser surgery is more widely used than semifemtosecond laser surgery because it is safer and has a better prognosis. It is very important to take care of your eyes after hemifemtosecond laser surgery. You should pay attention to the eye hygiene care, avoid touching your eyes with your hands; try not to overuse your eyes, use eye drops according to your doctor’s prescription and review them regularly; if you have myopia regression, you need to check the cause or need to perform the surgery again. Semi-femtosecond laser surgery is a method currently used to correct myopia and can be decided on an individual basis.
