Summary:To describe a novel technique for direct perfluorocarbon liquid (PFCL)-silicone oil exchange that aims to reduce the inherent risk of intraoperative intraocular pressure spike. We use the conventional setup for passive PFCL-silicone exchange, but intentionally create a mismatch between the passive PFCL aspiration and the active silicone injection that favors the PFCL extrusion. This is achieved by converting one port to a large gauge one-23 or 20-gauge. We did not note the occurrence of high intraocular pressure spikes with this technique as noted by disk pallor or attenuated vessels. A hybrid 23/25-gauge technique for direct PFCL-silicone oil exchange is safe and reduces the risk of intraoperative intraocular pressure spike.
