THE MAIN RESULTS OF THE TREATMENT OF MYOPIA AND MYOPIC ASTIGMATISM USING MODERN LASER TECHNOLOGIES
Laser correction is the main focus of treatment of refractive errors. Comparison of technologies simultaneously used in clinical practice in terms of efficiency and safety has not yet been completed. The purpose of the research is to conduct a comparative assessment of the effectiveness of laser technologies Femto LASIK and ReLEx SMILE for refractive errors correction. Materials and methods: The results of 2370 interventions were evaluated, including 1,424 (60.1%) using SMILE technology and 946 (39.9%) using LASIK. Visiometry, refractometry and pachymetry were made 1 and 6 months after surgery. Results and discussion. The application of the Femto LASIK and ReLEx SMILE methods does not give differences in the frequency of vision loss and its preservation at the preoperative level. At 1 month, there was a moderate advantage of LASIK technology regarding the degree of vision increase over SMILE. Within 6 months, no significant differences were revealed in any parameter, both in case of myopia and myopic astigmatism, there were a greater number of visual impairment cases in patients of the LASIK group. Conclusion: 1) The application of the Femto LASIK and ReLEx SMILE technologies in identical clinical conditions showed the absence of differences in the results with respect to changes in visual acuity over a period of 1 month. 2) When applying SMILE technology for a period of 6 months, the dynamics of visual acuity indicators increased in contrast to LASIK technology.
