“…This finding is consistent with a prior retrospective case–control study by Kobashi et al. (), which found a regression of −0.10 and −0.23 D for SMILE and LASIK, respectively, from 3 months to 2 years, but no statistically significant difference between the groups ( n = 30 eyes in each group).…”

Purpose: To compare visual outcomes and aberration outcomes in small incision lenticule extraction (SMILE) versus femtosecond laser LASIK (FS-LASIK). Methods: This prospective, comparative, nonrandomized clinical study included 68 eyes of 37 patients receiving SMILE and 55 eyes of 30 patients receiving FS-LASIK between December 2011 and January 2013 at the Fudan University Eye and ENT Hospital (Shanghai, People's Republic of China). Patients were followed up at 3, 6 months and 5 years after surgery. Main outcome measurements included uncorrected (UDVA) and corrected (CDVA) distance visual acuity, manifest refraction, central corneal thickness (CCT), total corneal refractive power (TCRP) and wavefront aberrations. Results: About 98% (49/50) of treated eyes in the SMILE group and 95% (39/41) in the FS-LASIK group had a postoperative logMAR UDVA of 0 or better. Spherical equivalent (SE) after 5 years was À0.01 AE 0.35 D in the SMILE group and À0.23 AE 0.41 D in the FS-LASIK group. A regression of À0.02 AE 0.39 D in the SMILE group and À0.12 AE 0.32 D in the FS-LASIK group was observed between 6 months and 5 years postoperative time-points. TCRP increased by 0.39 AE 0.38 D in the SMILE group and 0.45 AE 0.49 D in the FS-LASIK group between 6-month and 5-year time-points. However, no statistically significant difference was found between the SMILE and FS-LASIK groups in terms of ΔSE, ΔCCT and ΔTCRP between 6 months and 5 years postoperative time-points. Conclusion: Myopic regression was observed in terms of TCRP but not in subjective refraction. No statistically significant difference in stability was found between SMILE and FS-LASIK.

“…Sekundo et al [1] first introduced this new procedure in 2011. e first clinical study [2] of femtosecond lenticule extraction in China was also reported in 2011. Numerous clinical studies [3][4][5][6][7][8][9] suggested that SMILE is a safe and effective procedure for myopia correction, and the follow-up periods in these studies mostly spanned from 3 months to 3 years, but rarely up until 4 years [10][11][12][13][14]. In 2019, we [15] have previously compared the 5-year outcomes of SMILE and femtosecond laser-assisted LASIK (FS-LASIK) in patients with myopia.…”

Purpose. To investigate the long-term outcomes of refraction, corneal tomography, and wavefront aberrations after small incision lenticule extraction (SMILE) for moderate and high myopia. Methods. Prospective, nonconsecutive case series. A total of 26 patients (26 eyes) who underwent SMILE from May 2010 to March 2013 at the Fudan University Eye and ENT Hospital (Shanghai, China) were enrolled. The periods of follow-up were 1 month, 1 year, 5 years, and 7 years after surgery. The routine eye examinations included uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA), manifest refraction, and corneal tomography. Results. All surgeries were executed without any complications. At the final visit, an UDVA of 20/20 or better was achieved in 26 eyes (100%) and 11 eyes (42%) exhibited no change in CDVA. 9 eyes (35%) gained one line, 6 eyes (23%) gained two lines, and no eyes lost CDVA. 24 eyes (92%) and 26 eyes (100%) were within ±0.5 D and ±1.00 D of the target refraction, respectively. A mean refractive regression of −0.17 D was observed between 1 month and 7 years postoperatively. Mean corneal front curvature (MCFC) was significantly decreased between pre- and post-SMILE surgery (P<0.0001). Higher-order aberrations (HOAs) and vertical coma were significantly increased after SMILE compared to those measured before surgery (all P<0.001). There were no significant differences in trefoil and spherical aberration between pre- and post-SMILE surgery (all P>0.05). Conclusion. SMILE is an effective, safe, and stable procedure for moderate and high myopia, with relatively constant corneal stability and wavefront aberrations. This trial is registered with ChiCTR-ONRC-13003114.

“…The TIA and the SIA in the low astigmatic group were less than those in the high astigmatic group (p < 0.001). The CI and IOS [9] were also significantly lower in the low astigmatic group than in the high astigmatic group with p = 0.026. Figure 1 illustrated the UDVA postoperative in both groups.…”

BACKGROUND: Some studies have shown that there is a certain rotation of the eye in the sitting and lying position of the patient. The Visumax system used for the Refractive Lenticule Extraction-Small Incision Lenticule Extraction (ReLEx SMILE) surgery lacks the rotation of eye control function. So, is the ReLEx SMILE surgery for patients with astigmatism safe and effective? AIM: To evaluate the outcomes of the ReLEx SMILE surgery in cases with myopic astigmatism. METHODS: The case series included 120 eyes with myopic astigmatism undergoing ReLEx SMILE surgery from January 2018 to November 2018. The distribution of patients for two subgroups based on the power of astigmatism, low astigmatic group (≤ 1.50D) and high astigmatic group (> 1.50D). All patients were measured UDVA, CDVA, refractive sphere, astigmatism and sphere equivalent before and after surgery one week, one month and three months carefully. The astigmatic correction was evaluated by the vectorial analysis Alpins. RESULTS: The mean efficacy index of the low and high astigmatic group was 1.035 and 1.082 (respectively); the mean safety index was 1.113 and 1.215 (respectively). 93% of eyes in the low astigmatic group had an angle of error (AE) within ± 15 degrees and 100% in high astigmatic group. There was an undercorrection in astigmatic treatment. No complications during and after surgery were recorded. CONCLUSION: ReLEx SMILE surgery for the myopic astigmatic treatment was safe and effective.
