SBK(Sub Bowmans Keratomileusis) is a new LASIK procedure to make corneal flap under the anterior elastic layer. The thickness of the corneal flap is only 90- 1 10um, which is 30-60um more than that of the conventional operation, and the position of the corneal flap pedicle remains on the nasal side (traditionally, it is on the upper left). The nasal side is the most abundant part of corneal nerve. The operation does not cut off the corneal nerve on the nasal side, and the operation is done in one go without interruption, which reduces the exposure time of the cornea in the air and obviously relieves the symptoms of dry eye and discomfort after operation. The corneal flap made by SBK laser surgery technology is more accurate and smoother. The corneal flap made by one-time SBK under electron microscope is smoother than that made by femtosecond laser, which can effectively reduce postoperative glare and halo and improve postoperative visual quality. At present, SBK laser surgery is a safe and effective method to treat myopia, which is a supplement to conventional laser surgery and femtosecond laser. It has a high cost performance and is accepted and recognized by the majority of myopia patients.
