【 摘 要 】

Femtosecond laser small incision lenticule extraction(SMILE)is one of the most advanced corneal refractive operations at present. Different from other traditional corneal refractive operations, SMILE achieves minimally invasive and valveless operation. Therefore, the evaluation of postoperative visual quality of SMILE also has its own characteristics, at present, the latest research at home and abroad has confirmed that the naked eye vision can be significantly improved and the refractive status is stable after SMILE. However, there are different understandings of the objective visual quality indexes and their influencing factors, such as higher-order aberration, modulation transfer function cut off(MTF cut off)and objective scatter index(OSI)after SMILE. This paper reviews the postoperative visual quality and its influencing factors after SMILE to provide clinical help.
