Femtosecond Laser in Lower and Higher Myopia

2. SUMMARY Goal: The goal of this study was to evaluate the results and the efficiency of laser interventions where we use the femtosecond laser - FS-LASIK and ReLEx SMILE. We performed a retrospective data analysis by comparing the post-operational visual acuity development in a group of one hundred patients with lower and higher myopia and astigmatism. We also compared the influence of laser on the tear film and the macular thickness. Method: The studied cohort of patients consisted of two major groups. The first group included patients with lower myopia and the second group included patients with higher myopia. In each group, one half of the patients underwent the femtoLASIK surgery and the other half underwent the ReLEx SMILE surgery. We thus observed 50 patients (100 eyes) with lower myopia and 50 patients (100 eyes) with higher myopia. In the retrospective data analysis, we included patients younger than 45 years with the spherical equivalent of the myopic refractive error ranging from -0,75 to -4,12, concerning the group suffering from lower myopia, and ranging from -6,25 to -11,5, concerning the group suffering from higher myopia. Before the operations, we measured the uncorrected visual acuity of 1,0 in all patients. Results: During post-surgical check-ups, the values of uncorrected visual acuity..
