Clinical Outcomes of One Day Small-incision Lenticule Extraction Compared with Scheduled Methods for Myopic Patients

Purpose: To evaluate the clinical outcomes of one day small incision lenticule extraction (SMILE), which was performed on the same day as preoperative examinations in myopic patients. Methods: This study included 163 patients (163 eyes) who underwent SMILE with Visumax from January to June in 2017. We divided the patients into two groups. The one day SMILE group underwent surgery on the same day as the preoperative examinations including dilated fundus examinations. The scheduled group underwent the surgery on a different day. Only the right eye was included in the analysis. Visual acuity and refractive results were compared between groups. Results: The one day SMILE group included 83 patients and the scheduled SMILE group included 80 patients. At postoperative 1 month, the myopic errors were -0.07 ± 0.43 diopters (D) for the one day SMILE group and -0.09 ± 0.37 D for the scheduled SMILE group (p = 0.81); the astigmatic refractions were -0.48 ± 0.29 D and -0.46 ± 0.28 D, respectively (p = 0.57), the postoperative uncorrected visual acuities were -0.02 ± 0.11 logarithm of the minimum angle of resolution (logMAR) and -0.02 ± 0.11 logMAR, respectively (p = 0.79). At postoperative 6 months, the myopic errors were -0.06 ± 0.42 D for the one day SMILE group and -0.08 ± 0.34 D for the scheduled SMILE group (p = 0.81), and the astigmatic refractions were -0.48 ± 0.25 D and -0.48 ± 0.30 D, respectively (p = 0.99); the postoperative uncorrected visual acuities were -0.04 ± 0.09 logMAR and -0.05 ± 0.07 logMAR, respectively (p = 0.45). Conclusions: The postoperative results of the one day SMILE patients, whose surgery was performed on the same day as the preoperative dilating fundus examination were not significantly different compared with patients treated with conventional scheduled SMILE.
