AB  - PURPOSE: To compare posterior corneal elevation (PCE) changes and corneal 
      biomechanical changes post fematosecond laser-assisted laser in situ 
      keratomileusis (FS-LASIK) and small incision lenticule extraction (SMILE) 
      procedures using the Pentacam system and the Ocular Response Analyzer (ORA). 
      DESIGN: Retrospective observational case series study. METHOD: 106 patients with 
      bilateral myopia who underwent either FS-LASIK (56 patients) or SMILE (50 
      patients) were reviewed, only the right eye was used in the analysis. Inclusion 
      criteria include a spherical equivalent of -6.00DS and completion of 12 months 
      follow up. The main outcome evaluated was change in PCE at 3 months, 6 months and 
      12 months post-operation using the Pentacam system. Corneal biomechanical 
      parameters were evaluated at 6 and 12 months with the ORA. RESULTS: PCE change at 
      3 and 6 months were not significantly different between the two procedures 
      (p=0.064, p=0.109 respectively). At 12 months, PCE change was greater in FS-LASIK 
      than SMILE (p=0.048). One-way ANOVA showed that for either procedure, the change 
      in PCE did not differ at 3, 6 or 12 months post operation. CH and CRF values were 
      reduced after both procedures, with FS-LASIK demonstrating a greater reduction in 
      CRF than SMILE at 6 and 12 months (p=0.037 and p=0.001). Both CH and CRF 
      reduction correlated with PCE increase at 6 and 12 months. CONCLUSION: FS-LASIK 
      demonstrated a greater increase in PCE than SMILE only at 12 months, as well as a 
      greater reduction of CRF than SMILE. There were no significant differences in PCE 
      change over time within either group.
