PURPOSE: To compare the objective and subjective quality of vision after femtosecond laser-assisted small incision lenticule extraction (SMILE) and laser-assisted subepithelial keratomileusis (LASEK) for mild to moderate @entity1714 . METHODS: This prospective, comparative study included 65 eyes of 33 @entity1 in the SMILE group, with a mean spherical equivalent (SE) of -4.16    0.82 diopters, and 50 eyes of 25 @entity1 in the LASEK group, with a mean SE of -3.81    0.97 diopters. Visual acuity, corneal topography, contrast sensitivity, and wavefront aberrations were recorded preoperatively and compared with postoperative measurements. A quality of vision questionnaire was scored and analyzed 3 months postoperatively. RESULTS: Three months postoperatively, the SMILE group had fewer (P < .05) higher-order aberrations (HOAs) (0.390    0.175   m), including spherical aberration (SA) (0.262    0.242   m), than the LASEK group (HOAs = 0.479    0.148   m, SA = 0.576    0.287   m, trefoil = 0.465    0.248   m). There was no significant difference in the amount of @entity772 and trefoil between the two groups after surgery. Analysis of the scores of glare and halos in the quality of vision questionnaire revealed that SMILE (night glare = 1.25    1.22, halos = 0.97    1.12) provided a better quality of vision (P < .05) than LASEK (night glare = 2.32    1.99, halos = 1.96    1.77). The two groups demonstrated no significant difference in contrast sensitivity 3 months postoperatively. No vision-threatening complications were noted at any stage in either group. CONCLUSIONS: Both SMILE and LASEK are safe and effective surgical procedures in the correction of @entity1714 . SMILE has a lower induction rate of HOAs and a higher degree of @entity1 satisfaction than LASEK at 3 months postoperatively. [J Refract Surg. 2015;31(12):795-800.].
