[Enhancing the management and control of perioperative infection in small incision lenticule extraction]

Small incision lenticule extraction (SMILE) has been widely used in the treatment of myopia and astigmatism due to its small incision (2 mm), without open corneal flap, rapid recovery of the ocular surface function and good comfort. However, it is the microincision and the potential cavity under the corneal cap that provide a suitable environment for microbial nourishment. In this article, the characteristics of SMILE and the particularity of postoperative infection are stated, and the key points of risk management and control during the period of operation as well as the principles of identification and treatment of infection after SMILE surgery are put forward, so as to enhance the perioperative preparation in SMILE and make sure of the safety and high quality for myopic eyes.
