Anterior Vitrectomy: Vitreous Loss and Cortex Removal
This video demonstrates some of the issues that present when vitreous is lost. The incision is closed and the chamber is relatively formed during the anterior vitrectomy. Bimanual instrumentation is used, which allows control of the infusion and the cutting/aspiration. With a formed chamber and infusion high in the chamber and aspiration/cutting more posterior, the vitreous tends to stay back in its proper place. The residual cortical material is removed with the vitrector and cannula extraction (using a 23 gauge cortex extractor). The 3 piece acrylic MA50 IOL is placed in the sulcus with the Monarch injector eventually. A single piece acrylic intraocular lens cannot be placed into the sulcus, as the square haptics can cause an UGH (uveitis-glaucoma-hyphema) syndrome.
