 The article presents and evaluates the results of the first implantation of a Russian-made phakic posterior chamber intraocular lens (PCP IOL) model fIOL-3 to a patient with high hyperopia. The patient complained about poor vision in both eyes and expressed asthenopia complaints. Pre- and postoperative examination included visual acuity measurement, biomicroscopy, ophthalmoscopy, visual field test, tonometry, endothelial microscopy, ultrasound biomicroscopy (UBM) and optical coherence tomography (OCT). According to the data of pre-operative examinations, the diagnosis was made: OU high hyperopia, asthenopia. Since the patient had contraindications for laser refractive surgery, a method of implantation of PCP IOL model fIOL- 3 was proposed. The patient was operated on both eyes at intervals of 1 week. The operations were successful, without complications. At post-operative examination of the patient, the uncorrected visual acuity (UCVA) of the right eye was 1.0 and of the left eye was 0.8. According to autorefractometry data, the spherical component was improved from a 4.0 to 0.5 D on the right eye and from 5.25 to 1.0 D on the left eye. The influence of FIOL-3 implantation on IOP was not noted. UBM and OCT of the anterior segment of the eye showed that the haptic elements of FIOL-3 are located in the ciliary sulcus, and there is no contact between the FIOL and the native lens. The described clinical case confirmed that implantation of FIOL-3 to high hyperopia patients is a safe, effective, predictable, and stable method giving excellent clinical-functional results.

Key words: hyperopia, implantation, phakic IOL.
