Background. Myopia is the most common clinical refractive error of the eye. Only in Russia, there are about 15 million myopic people. Currently, in addition to traditional correction (glasses, soft contact lenses), keratorefractive surgery actively develops; however, due to the initial parameters of the cornea or the magnitude of the refractive error, it may be contraindicated to the patient. Nowadays an alternative to these correction methods for young patients with refractive errors of high and ultra-high degrees is the implantation of a phakic intraocular lens.The aim. To evaluate the efficiency of refractive errors correction using phakic IOL implantation.Materials and methods. We carried out a retrospective analysis of outpatient records of 56 patients who received surgical treatment for myopia and complex myopic astigmatism at the Orenburg branch of the S. Fyodorov Eye Microsurgery Federal State Institution in the period from 2019 to 2020 (110 eyes), all patients underwent implantation of a phakic intraocular lens IPCL V2.0, IPCL V2.0 TORIC. Patients were examined before surgery and on the first day after surgery. In addition to standard, special clinical and functional examination methods were used: optical biometry on the IOL-Master 700, determination of the density of endothelial cells using an endothelial microscope, examination of the fundus under cycloplegia; if necessary, peripheral laser coagulation of the retina was performed before calculating phakic IOLs.Results. All operations and the early postoperative period went without complications. The target BCVA (0.75–1.0) was achieved in 90 (81.8 %) eyes. All patients were satisfied with the treatment results.Conclusion. Implantation of IPCL V2.0 and IPCL V2.0 TORIC phakic IOLs is an effective method for correcting refractive errors, regardless of the degree of myopia and the presence of astigmatism.
