Is Xining all-laser myopia correction safe?

All-femtosecond laser surgery has changed the traditional way of making corneal flap. Micro-lens corneal tissue slices were made by starting femtosecond laser scanning twice, and a small shallow incision of 2-4 mm was made above the cornea to take out the thin corneal tissue with accurate quasi-correction made by femtosecond laser, so as to change the refractive power of the cornea and correct myopia, and truly realize no knife, no flap, minimally invasive and rapid. Aier introduced full femtosecond laser myopia surgery, which is relatively safe.
