Removal of OVD

Removal of OVD (ophthalmic visco-surgical devices) Since OVDs often remain behind the IOL, it is recommended to insert an I / A tip under the IOL for aspiration, but for beginners it is a high hurdle and offers an alternative. Place the tip of the I / A tip in the center of the front of the IOL to maximize the suction pressure and suck the OVD. Since the OVD has a viscous force, the OVD behind the IOL is also sucked together with the OVD in front of the IOL. At this time, the IOL is violently shaken, which is a sign that the OVD has been sucked. The OVD may remain partially, but if you perform 360 degree suction along the edge of the IOL with the suction port of the I / A tip facing down, the rest will also be sucked. At this time, the IOL oscillates, so it is a sign that the OVD has been removed. In addition, if the boundary between the partially remaining OVD and the perfusate can be clearly confirmed, ODV can be aspirated by applying suction near the edge of the IOL. The dispersive OVD attached to the posterior surface of the cornea is so sticky that it cannot be completely aspirated. Fortunately, it is unlikely to cause infection or high intraocular pressure, so leave it.
