Abstract
PURPOSE: To assess the early time course of the visual function after small-incision lenticule extraction (SMILE) and laser in situ keratomileusis (LASIK). SETTING: Quinze-Vingts National Ophthalmology Hospital, Paris, France. DESIGN: Prospective case series. METHODS: Patients scheduled for bilateral small-incision lenticule extraction or LASIK were consecutively enrolled. In addition to standard refraction and visual acuity, contrast sensitivity, aberrometry, and patient-reported quality of vision and overall satisfaction were measured 1 day, 7 days, and 1 month postoperatively. RESULTS: Each group comprised 23 patients (46 eyes). The postoperative contrast sensitivity was better in the LASIK group at 1 day (P = .014) and 7 days (P = .001) but not at 1 month. No significant differences in visual acuity, efficacy, or safety were found between the 2 groups throughout the follow-up. The objective scatter index assessed by double-pass aberrometry was better after LASIK 1 day postoperatively (P = .036) but was not statistically different thereafter. The patient-reported quality of vision was significantly worse in the small-incision lenticule extraction group than in the LASIK group at 7 days (P = .010). Global satisfaction did not differ between groups throughout the study. Significant correlations were found between contrast sensitivity and aberrometry in both groups at all examinations. CONCLUSIONS: Targeted analysis of early quality of vision through objective and subjective methods suggested that compared with LASIK, a slight delay in corneal optical recovery after small-incision lenticule extraction might lead to reduced contrast sensitivity and specific patient-reported visual disturbance during the first postoperative week with no effect on overall patient satisfaction.
