Abstract: femtosecond laser has truly realized the “all laser” era of myopia treatment. Compared with corneal lamellar knife, the accuracy of femtosecond laser is more than 100 times that of lamellar knife, which is safer for any patient., At present, with the improvement of people’s living standards, people have higher and higher requirements for visual quality after myopia surgery, and the surgery of laser treatment of myopia is also upgrading. From the previous excimer laser to the current femtosecond laser, femtosecond laser has completed a technological leap compared with the previous excimer laser, It completely replaces the previous mechanical corneal lamellar knife. Femtosecond laser can make corneal flap or laser cutting, and completely eliminates the side effects of corneal lamellar knife in making corneal flap., Characteristics of femtosecond laser: 1 High accuracy; 2. Very high instantaneous power; 3. It has the characteristics of accurate target focusing and positioning, and can focus on the ultra-fine spatial area with much smaller hair diameter; 4. Femtosecond laser surgery, no thermal effect and shock wave, the whole process will not have tissue damage., The advantages of femtosecond laser in the treatment of myopia: 1. The operation risk is greatly reduced; For example, the risk of corneal lamellar knife infection and the risk of making corneal flap are greatly reduced. 2. The profile of corneal flap made by corneal lamellar knife is “cup cover” type, and the fixation with eyeball matrix is not good enough. However, the embedded corneal flap made by femtosecond laser has accurate reduction and good fixation. 3. The postoperative visual quality is more perfect. “Femtosecond laser” can accurately open the molecular chain of eye tissue, make a more uniform and perfect corneal flap, effectively avoid the possible iatrogenic aberration of lamellar knife flap, and avoid the glare and blur under visual conditions such as fog, rain and driving at night, Let myopia get perfect visual quality., 100 times more accurate., Femtosecond laser has truly realized the “all laser” era of myopia treatment. Compared with corneal lamellar knife, the accuracy of femtosecond laser is more than 100 times that of lamellar knife, which is safer for any patient., With the above advantages, we have entered a new era, and the surgical safety has been greatly improved, which can make patients worry free and accept this technology more easily. Since the development of femtosecond laser in Kaifeng Eye Hospital, the proportion of femtosecond laser in corneal refractive surgery has increased day by day. Now, the proportion of femtosecond laser in the surgical methods of laser treatment of myopia is more than 90%, because the information society makes the people know the most advanced technical means – femtosecond laser for the first time, Let them know the unprecedented advantages brought by this advanced technology before entering the hospital again. For their own tomorrow, they will not hesitate to choose femtosecond laser, so that their eyes can meet the brilliant tomorrow more clearly and comfortably under the action of femtosecond laser.,
at present, with the improvement of people’s living standards, people have higher and higher requirements for visual quality after myopia surgery, and the laser surgery for myopia is also being updated. From the previous excimer laser to the current femtosecond laser, femtosecond laser has completed a technological leap compared with the previous excimer laser, It completely replaces the previous mechanical corneal lamellar knife. Femtosecond laser can make corneal flap or laser cutting, which completely eliminates the side effects of corneal lamellar knife in making corneal flap. Characteristics of
femtosecond laser: 1 High accuracy; 2. Very high instantaneous power; 3. It has the characteristics of accurate target focusing and positioning, and can focus on the ultra-fine spatial area with much smaller hair diameter; 4. Femtosecond laser surgery, there is no thermal effect and shock wave, and there will be no tissue damage in the whole process. The advantages of

is increased by one hundred times.
