[LASER CORRECTION OF MYOPIC ASTIGMATISM USING FEMTO LASIK AND RELEX SMILE TECHNOLOGIES - EFFICIENCY AND SAFETY].

The purpose of the study is a comparative analysis of the efficacy and safety of the Femto LASIK and ReLEx SMILE technologies in correcting myopic astigmatism. Materials and methods: The study included 1212 results of interventions in patients with myopic astigmatism, incl. 721 (59.5%) using ReLEx SMILE technology and 491 (40.5%) Femto LASIK technology. Visionometry and refraction investigation were performed at the time of 3, 6, 9, 12 months after the operation, as well as an analysis of the incidence of complications. Results of the study: As a result of the study, it was determined that in patients with myopic astigmatism, laser correction of refractive error using ReLEx SMILE technology gives similar results to Femto LASIK in the presence of a combination of moderate myopia and mild astigmatism. With medium-level astigmatism, the clinical results of Femto LASIK decrease (the difference in this category of patients after 1 week was 12.7% (p=0.04), they were also significant after 3 months (11.9%, p=0.042) and 9 months (8.9%, p=0.048)), which, nevertheless, remain quite satisfactory. The use of the ReLEx SMILE technique provides a significant reduction in the number of complications of laser correction of refractive errors, with both light astigmatism (3.2 times) and more pronounced violations (2.6 times). Significant differences were revealed in the frequency of dry eye syndrome (4.7 times, χ2=23.22, p=0.001), hypercorrection 14.3 times (χ2 = 34.52, p <0.001) in favor of the ReLEx SMILE technique.
