An electrically-powered, portable component of an intraocular pressure-reducing vacuum system designed for use by a healthcare professional to create and control negative pressure around the eye for the noninvasive, bilateral reduction of intraocular pressure (IOP) for the treatment of open-angle glaucoma. It is in the form of a small unit with connection points for suction and sensing tubing which are attached to the lenses of intraocular pressure-reducing vacuum system goggles (not included). This is a reusable device.
