Assessment of the safety and effectiveness of lens surgery using three-dimensional visualization based on the analysis of long-term results of operations. Material and methods. The study involved 500 patients (500 eyes). The main group consisted of 250 patients with cataracts operated by phacoemulsification using the NGENUITY three-dimensional digital imaging system. The control group consisted of 250 patients using analog imaging, i.e. using standard eyepieces. Long-term results were evaluated 3, 6 and 12 months after surgery using parameters such as uncorrected and maximally corrected visual acuity, refractometry indicators and corneal endothelial cell density. Results. Although in the long-term period we did not record statistically significant differences between the achieved indicators of visual acuity, refractometry and density of corneal endothelial cells in the main and control groups, their average values were still slightly higher in the group of patients where three-dimensional digital imaging was used in the FEC process. Conclusion. The long-term results of a comparative study of visual acuity, endothelial cell density, spherical and cylindrical components of refraction when using analog and three-dimensional digital imaging in cataract surgery allow us to conclude that the latter method is still more effective than the standard one. All this, combined with great ergonomic capabilities, makes it possible to recommend three-dimensional digital visualization for wider dissemination in clinical practice. Key words:cataract surgery, three-dimensional digital visualization, standard analog visualization, visual acuity, refraction, density of endothelial cells
