RISK FACTORS AND SURGICAL APPROACH FOR PARS PLANA VITRECTOMY OF POSTERIORLY DISLOCATED INTRAOCULAR LENSES

The retrospective study was conducted in the Department of Ophthalmology, Nishtar Medical Hospital, and Bakhtawar Amin Trust Hospital from January 2022 to 2023 evaluate risk factors surgical approach for posterior dislocation intraocular lens into vitreous requiring pars plana vitrectomy. A total 30 eyes patients (20 male 10 female) were included study. Standard PPV vitrectomy performed all patients. Iris fixation technique used having a 3-piece design. sclera secure prevent it falling onto retina. IOL (Intra-Ocular Lens) exchanged which previously damaged. Results showed that 28 (93.3%) eyes, original conserved positioned on scleral wall, iris, or both. existing could not be preserved 2(6.6%) eyes. 92.1% cases had single factor dislocation. After surgery, uncorrected visual acuity (UCVA) improved 20/400 initial visit 20/80 final (P=0.001). UCVA remained unchanged 3 (10%) 27 (90%) It can concluded incidence has been increasing. Intravitreal substance injections, myopia, previous are major factors. In most cases, secured chamber through
