Semi-femtosecond laser surgery combines the characteristics of femtosecond laser and excimer laser. First, make a flap on the cornea with femtosecond laser. After the corneal flap is completed, switch to excimer laser mode, and use excimer laser to complete the subsequent corneal stroma cutting. All-femtosecond laser surgery uses femtosecond laser in the whole process and will not switch with other laser modes. The key of full femtosecond laser surgery is not to cut the corneal flap and then cut it by laser, but to directly cut the upper and lower layers of corneal stroma, and then take out the lens through a small incision in the cornea with special instruments. Semi-femtosecond surgery may lead to corneal flap heterotopia and corneal flap wrinkle, while full femtosecond surgery is relatively safer because of its very small incision. The full femtosecond wound is smaller, the wound will be smaller, and the safety is slightly different. If you get a big impact. Click to test whether I am suitable for myopia surgery.
