Popis: Introduction. The use of phakic intraocular lens (PIOL) for the correction of high ametropia is reflected in the works of both domestic and foreign ophthalmologists. In spite of this, there are very few publications which are devoted to the long-term outcomes of the use of domestically produced models of PIOL such as RSK-1(3) and RSK-3.Purpose. The main aim of this work is to assess the clinical and functional outcomes of the use of domestically produced models of PIOL such as RSK-1(3) and RSK-3.Material and methods. A retrospective analysis of the long-term results of PIOL implants performed at the Fyodorov Eye Microsurgery Federal State Institution was carried out from 1994 to 2001. The analysis involved 122 eyes of 84 patients with high myopia from who were implanted with posterior chamber negative PIOL with two haptic elements (RSK-3) and PIOL with thr ee haptic elements (RSK-1(3). Results. Analysis of the dynamics of postoperative refractive data in compare with preoperative parameters showed us that in all cases there was a significant increase in uncorrected and corrected visual acuity. Long-term outcomes of implantation were found in 25 patients (43 eyes). The average duration of PIOL in the eye was 14.30±1.3 g (from 2 to 30 years). In all cases, the reducing cell density of the corneal epithelium did not exceed 4.0% in the early postoperative period. At the same time, the main complication in the distant postoperative period was the development of subcapsular cataracts.Conclusions. This method of ametropia correction can be recommended to young patients, who are not suitable for keratorefraction interventions.
