Slit-lamp fluid-gas exchange and other office procedures following vitreoretinal surgery.

Many complicated postoperative vitreoretinal cases require reoperations. It is possible to perform some of these procedures outside the operating room. We describe examining room techniques for fluid-gas exchange, fluid and gas aspiration, and adherent vitreous strand removal. We also discuss a slit-lamp technique for using sodium hyaluronate (Healon) following fluid-gas exchange to eliminate optical distortion from endothelial striae.
