“…Besides, Agca et al [13] demonstrated 5-year results of 37 cases with high myopia, in which 59% of them are within ±0.50 D of the intended correction, and 92% of them are within ±1.00 D. ey clarified that it was most likely attributed to a greater tendency toward undercorrection. Agca et al [14] showed that 93% of eyes were within ±0.50 D of the intended correction and 100% were within ±1.00 D among patients with mild-to-moderate myopia.…”

“…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.

“…In the literature, the efficacy index of SMILE in cases of high myopia is lower than that in cases of mild to moderate myopia. At a 5-year visit, Alper Ag˘ca reported an efficacy index of mild-to-moderate myopia of 0.98 ± 0.21 and found that 54 of the eyes (80%) achieved a postoperative UDVA of 20/20 or better [12]. However, the efficacy index of high myopia has been found to be 0.89 ± 0.26, with 37 of the eyes (30%) achieving a postoperative UDVA of 20/20 or better [9].…”

KEYWORDSSmall incision lenticule extraction (SMILE), high myopia, long-term follow-up 2 Abstract Background To investigate long-term refractive visual quality outcomes and vision-related quality of life after small-incision lenticule extraction (SMILE) in the treatment of high myopia.Methods Thirty patients (60 eyes) with high myopia who underwent SMILE more than 5 years previously were selected as the SMILE group. Another 30 high myopia patients (60 eyes) who had worn corrective spectacles for more than 5 years were selected as the control group. In the SMILE group, the postoperative follow-up times were 3 months, 6 months, 1 year and 5 years. The uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical equivalent (SE), and ocular axial length (AL) were analysed. The Chinese version of the National Eye Institute Visual Function Questionnaire-25 (CHI-NEI-VFQ-25) was used to evaluate the vision-related quality of life in the SMILE group and the control group. ResultsIn the SMILE group, the mean preoperative SE was -7.29±0.87 D (range -6.00 to -9.125 D).The efficacy index and safety index of SMILE were 1.09±0.18 and 1.19±0.12, respectively. Five years postoperatively, 44 eyes (73%) obtained a visual acuity of 20/20 or better. There were no eyes with CDVA loss of one or more Snellen lines. Forty-nine eyes (82%) and 57 eyes (95%) were within ±0.50 D and ±1.00 D of attempted correction, respectively. Forty-eight eyes (80%) had astigmatism < 0.50 D. The postoperative mean SE values at 3 months, 6 months, 1 year, and 5 years were 0.11±0.44 D, 0.07±0.45 D, -0.02±0.41 D, and -0.15±0.46 D, respectively. No significant change was observed in the ocular axial length from before operation to 5 years postoperatively (26.08±0.96 mm vs 26.01±0.94 mm, p>0.05). Compared to the control group, the SMILE group showed a significantly higher total score on the CHI-NEI-VFQ-25 (90.14 vs 81.43, p < 0.001). ConclusionsIn the present study, in a long-term follow-up, we demonstrated that correcting high myopia with SMILE is safe, effective, and predictable. In addition, there is slight undercorrection. BackgroundRecently, femtosecond lasers have been widely used in ophthalmology, such as in anterior capsulotomy with femtosecond lasers in cataract surgery, femtosecond laser-assisted keratoplasty, flap construction with femtosecond lasers in FS-LASIK and lens creation in the corneal stroma with
