The prevalence of myopia is increasing and there are various treatment options, among which laser surgery has gradually become the main modality for myopia treatment. There are mainly scarless and scarred laser surgeries, which can also be called superficial and lamellar surgeries, and some are also called flap and flapless surgeries. There are many types of laser surgery, but they all work on the cornea. The cornea is divided into five layers, and laser surgery mainly works on the third stromal layer of the cornea because the stromal layer is the last layer of the cornea and cannot be regenerated after damage, which also ensures that the long-term results of myopia surgery will not occur due to regeneration of the cut tissue. The commonly used superficial surgery is excimer laser superficial cutting (PRK), which involves soaking the corneal epithelium in alcohol, then scraping the corneal epithelium with an instrument, and finally cutting with an excimer laser; T-PRK is also a superficial surgery, which uses a laser for the entire procedure. Compared to PRK, the procedure is shorter, with less postoperative reaction and a shorter recovery time. The most common types of laminar surgery are full femtosecond and half-fractional second surgery. Full Femtosecond surgery uses a femtosecond laser to make a lens in the third stromal layer of the cornea to match the prescription, then a two-millimeter incision is made to remove the lens and the surgery is complete. Semi-femtosecond surgery is performed with a femtosecond laser to create the flap, then in the stroma, the excimer laser is used to make the cut. The difference lies in the different equipment used, some start from the epithelial layer, while others operate directly on the corneal stroma.
