TI  - Three-year outcomes of small incision lenticule extraction (SMILE) and

AB  - AIMS: To compare long-term clinical outcomes following small incision lenticule 
      extraction (SMILE) and femtosecond laser-assisted laser in situ keratomileusis 
      (FS-LASIK) for myopia and myopic astigmatism correction. METHODS: In this 
      retrospective study, we enrolled a total of 101 patients (101 eyes) who underwent 
      SMILE or FS-LASIK 3 years prior. Measured parameters included uncorrected 
      distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest 
      refraction and corneal wavefront aberrations. RESULTS: No significant differences 
      in patient characteristics were found between the two groups. At the 3-year 
      follow-up, UDVA was better than or equal to 20/20 in 90% and 85% (p=0.540) of the 
      eyes; the efficacy indexes were 1.05+/-0.19 and 1.01+/-0.21 in the SMILE and FS-LASIK 
      groups, respectively (p=0.352). Safety indexes were 1.19+/-0.17 and 1.15+/-0.20 in 
      the SMILE and FS-LASIK groups, respectively (p=0.307). Eighty per cent and 65% of 
      eyes were within +/-0.50 D of the attempted spherical equivalent correction after 
      SMILE and FS-LASIK, respectively (p=0.164). Vector analysis revealed no 
      significant differences in astigmatic correction between the two groups (p>0.05). 
      Surgically induced spherical aberration was higher in the FS-LASIK group than in 
      the SMILE group (p<0.001). CONCLUSION: Long-term follow-up analysis suggested 
      that both SMILE and FS-LASIK were safe and equally effective for myopic and 
      astigmatic correction.
