TI  - Corneal Higher-Order Aberrations of the Anterior Surface, Posterior Surface, and 
      Total Cornea After SMILE, FS-LASIK, and FLEx Surgeries.

AB  - OBJECTIVES: To investigate the corneal higher-order aberrations (HOAs) of the 
      anterior surface, posterior surface, and total cornea after small incision 
      lenticule extraction (SMILE) and compare the results using femtosecond 
      laser-assisted in situ keratomileusis (FS-LASIK) and femtosecond laser lenticule 
      extraction (FLEx). METHODS: This study included 160 eyes in total; 73 eyes 
      underwent SMILE, 52 eyes underwent FS-LASIK, and 35 eyes underwent FLEx surgery. 
      Corneal HOAs of the anterior surface, posterior surface, and total cornea were 
      evaluated using a Scheimpflug camera over 6-mm diameter preoperatively and 3 
      months postoperatively. RESULTS: The anterior and total corneal HOAs 
      significantly increased after SMILE, FS-LASIK, and FLEx surgeries, especially the 
      spherical aberration and coma, whereas most posterior corneal HOAs remained 
      unchanged. The SMILE procedure induced significantly lower anterior corneal and 
      total corneal spherical aberration and third to eighth HOAs compared with FLEx 
      surgery (P<0.01). FLEx surgery induced higher posterior corneal coma than SMILE 
      (P=0.013) and FS-LASIK (P<0.001) surgeries. CONCLUSIONS: SMILE, FS-LASIK, and 
      FLEx surgeries mainly induced coma and spherical aberrations in the anterior 
      surface and total cornea. The SMILE procedure induced less spherical aberration 
      of the anterior cornea and total cornea than FLEx surgery. The posterior corneal 
      spherical aberration significantly increased after FS-LASIK surgery. The SMILE 
      procedure seems to have fewer effects on posterior corneal coma compared with the 
      FLEx procedure.
