Participants and treatment procedures
EYE
In the present study, 180 patients (360 eyes), who underwent SMILE at the Eye Center of Fujian Medical University between July and November 2019, were randomly divided into three groups using a random number table, with 60 patients (120 eyes) in each group. The protocol for the SMILE procedure was the same as the protocol described by Liu et al. [All patients received 0.5% levofloxacin eye drops (Santen Pharmaceutical Co., Ltd., Osaka, Japan) for four times a day, which was immediately administered after the SMILE procedure, and 0.1% fluorometholone (FML) eye drops (Santen Pharmaceutical Co., Ltd., Osaka, Japan), which were administered within two hours after the SMILE procedure (except for group A), and for four times a day starting from the second day after the SMILE procedure. According to the regimen for FML administration after SMILE, the patients were divided into three groups: no FML in group A, 0.1% FML once every hour (twice in total) in group B and 0.1% FML once every half hour (four times in total) in group C.
