Reimplantation of an intraocular lens (IOL) remains a relevant procedure for managing postoperative complica tions following cataract phacoemulsification, including ametropia, decentration, and IOL displacement. However, standard IOL reimplantation techniques, despite their widespread use, are associated with an increased risk of endo thelial trauma, the need for incision enlargement, and a higher incidence of induced astigmatism. This necessitates the development of less invasive, more precise, and more controlled surgical approaches. The aim of our study was to compare the effectiveness and safety of the standard IOL reimplantation technique with a modified triangular bisection method during the early postoperative period. A retrospective-prospective study was conducted involving 60 patients (60 eyes), aged 55-82 years, who were divided into two groups: the main group – standard technique (35 eyes) and the comparison group – modified technique (25 eyes). The standard approach required widening the inci sion to 3.0-3.2 mm and rotating the IOL into the anterior chamber. The modified method involved mobilizing the IOL from the capsular bag, applying dual-layer OVD protection, and performing triangular bisection, allowing removal of the lens fragment through a 2.2-2.6 mm incision without enlargement. Functional outcomes demonstrated a statis tically significant improvement in best-corrected visual acuity in the comparison group (p=0.011), as well as greater IOL positional stability and a lower incidence of corneal edema, hypotony, and intraocular pressure elevation. The modified triangular bisection technique provides reduced surgical trauma, improved IOL centration, and a lower rate of complications compared to the standard approach. This method may be recommended as an optimal option for IOL reimplantation in acquired ametropias within up to two months after the primary procedure.
