All-femtosecond surgery and semi-femtosecond surgery are both laser orthokeratology, which can be used to correct myopia. However, the choice of full femtosecond or semi-femtosecond surgery depends on the doctor's advice and personal situation. The following are the general characteristics of these two operations:
All-femtosecond surgery, also known as smile surgery, is a kind of myopia correction surgery using femtosecond laser equipment throughout the operation. All-femtosecond laser surgery mainly uses femtosecond laser to make corneal microlens on corneal stroma. As long as the surgeon takes out the lens, the operation is completed, and the biomechanics of the whole cornea is more stable. This surgical technique can provide more accurate and predictable correction results, while reducing the process of valve making in traditional surgery.
Semi-femtosecond surgery, also known as LASIK surgery or FS-LASIK surgery, is a myopia correction surgery that combines femtosecond laser equipment and excimer laser equipment. In semi-femtosecond surgery, the corneal flap is made by semi-femtosecond laser, and then the cornea is ablated by excimer laser. Compared with full femtosecond surgery, semi-femtosecond surgery needs to make corneal flap, so postoperative care and recovery need more energy and time.
Please note that the choice of operation method should be decided according to the doctor's advice and personal situation. In addition to the degree, doctors will also consider other factors, such as eyeball health, corneal thickness, corneal curvature and so on. To determine the most suitable surgical method for you.
