Abstract
The formation of secondary cataracts in patients with high-grade myopia remains the main cause of vision loss in the long-term postoperative period. Taking this into account, a soft model of posterior chamber «reverse» IOL was developed in the Fyodorov Eye Microsurgery Federal State Institution, Moscow, which allows reducing the development of secondary cataracts. Purpose. Comparative analysis the clinical and functional results of implantation of «reverse M and M1» IOL in patients with high myopia in the long-term follow-up. Materials and methods. Clinical studies were conducted on 140 eyes of 97 patients with high-grade myopia aged from 42 to 83 years (on average, 64.24±0.79 years) after phacoemulsification cataract (FEC) with IOL implantation in high-grade myopia. The main group consisted of 57 eyes of 40 patients who were implanted with «reverse-M1» IOL, the control group-83 eyes of 57 patients who were implanted with «reverse-M» IOL. Visual acuity before surgery without correction in any patient did not exceed 0.01, and with the maximum correction was no more than 0.2 (80%). The follow-up period was up to 5 years. Results. Visual functions in the majority of patients increased and remained stable throughout the postoperative period, amounting to 0.55+0.04 in the main group, and 0.54+0.03 in the control group. In the late postoperative period, dissection of the posterior lens capsule with «reverse-M» IOL was performed in 11 eyes of 13 patients (13.2%), in the main group, YAG laser dissection of the posterior capsule was required in 2 patients with 3 eyes (5.3%). Conclusions. Implantation of a «reverse-M1» IOL is safe, predictable and allows you getting less PCO formation compare with «reverse-M» IOL in the long-term follow-up in patients with high myopia. Keywords: phacoemulsification cataract, implantation of «reverse» IOL, high myopia.
