PURPOSE: To compare the visual and refractive out-comes of femtosecond laser-assisted LASIK with small-incision lenticule extraction (SMILE) in terms of visual acuity, contrast sensitivity, aberrations, and @entity936 . METHODS: A single-center prospective randomized study in which @entity1 diagnosed as having @entity1714 presenting for refractive correction were allocated to either a LASIK or SMILE group. The primary outcome measures were refractive efficacy, predictability, and safety, postoperative contrast sensitivity, aberrations, and @entity936 status. @entity1 were followed up at days 1 and 15 and 3 months; postoperative uncorrected visual acuity (UCVA), aberrations, @entity936 , and contrast sensitivity were recorded and compared to preoperative data. Two postoperative subjective questionnaires were used to assess @entity158 , pricking sensation, redness, glare, and overall @entity1 satisfaction. RESULTS: At day 1 postoperatively, 48 (96%) of 50 eyes in the SMILE group achieved a UCVA of 20/20 compared with 46 (92%) of 50 eyes in the LASIK group. At day 15 postoperatively, contrast sensitivity was similar in the two groups (P = .15), but by 3 months, it was better in the SMILE group than the LASIK group at all spatial frequencies (P < .0001). At 3 months postoperatively, 42 (84%) eyes in each group achieved a UCVA of 20/20, with 6 (12%) eyes in the SMILE group and 2 (4%) eyes in the LASIK group achieving 20/15. Higher-order aberrations at 3 months postoperatively were significantly higher in the LASIK group (0.437 + 0.103 pm) than in the SMILE group (0.267 + 0.07 pm; P < .001). Postoperative @entity936 and glare were significantly more common following LASIK (P < .001). CONCLUSIONS: Three-month results demonstrate that refractive accuracy, @entity936 , contrast, and induced aberrations are better following SMILE rather than LASIK.
