PARS PLANA VITRECTOMY, PHACOEMULSIFICATION AND INTRAOCULAR LENS IMPLANTATION FOR THE MANAGEMENT OF CATARACT AND PROLIFERATIVE DIABETIC RETINOPATHY: COMPARISON OF A COMBINED VERSUS TWO-STEP SURGICAL APPROACH VITRECTOMÍA PARS PLANA, FACOEMULSIFICACIÓN E IMPLANTE DE LENTE INTRAOCULAR PARA EL MANEJO DE CATARATA Y RETINOPATÍA DIABÉTICA PROLIFERATIVA: COMPARACIÓN DE TÉCNICA QUIRÚRGICA COMBINADA VERSUS EN DOS TIEMPOS

Purpose: To report the intra-and postoperative complications and visual acuity outcomes in pars plana vitrectomy (PPV), phacoemulsification and intraocular lens (IOL) implantation in patients with cataract and proliferative diabetic retinopathy (PDR). A comparison of the combined versus twostep surgical approach is given. Method: Retrospective uncontrolled interventional clinical trial. Forty-eight eyes of 48 consecutive patients with PDR were included. Twenty-eight (58.3%) eyes with combined surgery and 20 (41.7%) eyes with sequential surgery were analyzed. Results: Postoperative follow-up time was between 6 and 63 months (mean: 18 months). 1) Combined surgery: Preoperative best-corrected visual acuity (BCVA) ranged from 20/200 to hand motions, and
