Clinical Outcomes Of Beveled Tip, Ultra-High Speed, 25-Gauge Pars Plana Vitrectomy System

Abstract

\n OBJECTIVE\n\nTo report clinical outcomes of a 25-gauge, beveled-tip, 10000 cuts-per-minute (cpm) microincisional vitrectomy surgery (MIVS) system.\nMETHODS\n\nProspective case series of eyes undergoing primary pars plana vitrectomy (PPV) for common indications. Main outcome measures were: rate of achieving surgical objectives, operative time, number of surgical steps, use of ancillary instruments, corrected distance visual acuity (CDVA), and adverse events (AE).\nRESULTS\n\nSurgical objectives were achieved in all eyes. Mean total operative, core, shave and total vitrectomy times were 1891\u2009±\u2009890, 204\u2009±\u2009120, 330\u2009±\u2009320, 534\u2009±\u2009389 seconds, respectively. Mean number of surgical steps was 4.3\u2009±\u20091.5. Mean number of ancillary instruments used was 4.5\u2009±\u20091.9. Mean CDVA improved by 0.53\u2009±\u20090.56 logMAR units (P\u2009<\u20090.001) after 3 months. Postoperative AE included elevated IOP (8%), hypotony (6%), and re-detachment (2%). Majority (82%) had no postoperative discomfort.\nCONCLUSION\n\nBeveled-tip, 10000 cpm MIVS system effectively and safely performs common vitreoretinal procedures and may reduce operative time and ancillary instrumentation.
