An assembly of manually-operated devices designed to reduce the intraocular pressure (IOP), i.e., internal pressure of the eye fluids, by applying a controlled, external, mechanical compression to the surface of the eye in preparation for ophthalmic surgery. It typically consists of a headband with an attached inflatable bellows that applies pressure, an air pump (e.g., a squeeze bulb), a pressure indicator (e.g., a manometer), and tubing. It is typically used prior to surgery to induce a temporary reduction of the IOP creating a condition known as "soft surgical eye", which helps in the prevention of haemorrhaging thus reducing the risk of a surgical procedure. This is a reusable device.
