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.
