Induced changes in wavefront aberrations (6.0-mm analysis corneal diameter) in the SMILE and LASEK groups. Postop: postoperative; RMS: root mean square; HOAs: higher-order aberrations; Z4,0: spherical aberration; Z3, -3: oblique trefoil; Z3, -1: vertical coma; Z3, 1: horizontal coma; Z3, 3: horizontal trefoil. SMILE: small incision lenticule extraction; LASEK: Laser-assisted subepithelial keratomileusis
