Abstract

Objectives:Our aim is to evaluate the safety, efficacy, predictability, and clinical outcome of femtosecond laser-assisted in situ keratomileusis (FS-LASIK) procedures performed on the day of the initial consultation relative to procedures performed at subsequent visits.Methods:A retrospective cohort study design was used. The study group included patients with myopia of different severities who were treated with FS-LASIK in 2013 through 2014 in an optical outpatient clinic of a large private medical service. Inclusion criteria were at least 18 years of age, a stable refraction for 12 months, no history of autoimmune disease, ocular surgery, or eye disease, and complete medical records. Background, clinical, and outcome data were collected from the patient files.Results:Femtosecond laser-assisted in situ keratomileusis was performed in 80 patients (160 eyes) at the first visit and 361 patients (719 eyes) at a subsequent visit. The mean±SD spherical equivalent (SE) refraction before surgery was -3.74±2.03 D in the first-visit group and -3.73±1.87 D in the subsequent-visit group (P=0.99). Efficacy index values were 0.97±0.15 in the first-visit group and 0.98±0.13 in the subsequent-visit group (P=0.92), and corresponding safety index values were 0.99±0.15 and 0.99±0.12 (P=0.81). The final SE measured -0.09±0.58 D in the first-visit group and -0.19±0.55 D in the subsequent-visit group (P=0.05). Types and rates of complications were similar in the two groups.Conclusions:There is no significant difference in the results of refractive surgery with FS-LASIK between procedures performed at the initial or subsequent visits. In both conditions, FS-LASIK surgery is associated with excellent safety, efficacy, and predictability profiles.
