With the more advanced technology configuration, the operation is more precise and safer, with minimal impact on the biomechanics of the cornea. The damage to the corneal surface is also reduced, which ensures the integrity of the cornea to the greatest extent. On the other hand, SMILE surgery is a flapless surgery, which also avoids flap-related complications to a certain extent after surgery and reduces the impact of post-operative eye rubbing and trauma on the surgical results, making patients and surgeons more at ease. Since the surgery is safer and the visual quality is more perfect, it is more suitable for public security police or people who like sports and outdoor work. After the surgery, patients said that the surgery is short and quick recovery, less than 30 minutes, and they can use their eyes normally the next day after the surgery on the first day. It is believed that this technology will bring clear vision to more myopic patients.
