A manual ophthalmic tonometer is a diagnostic instrument used to measure intraocular pressure by applying direct force to the surface of the eye. By assessing the eye's resistance to deformation, these devices provide a reading in millimeters of mercury that helps clinicians screen for and manage conditions like glaucoma.
These instruments are designed for physical contact with the eye and may be operated as handheld tools or mounted to a slit lamp for stability. Users should note that these devices rely on manual operation to determine corneal indentation and are intended for professional clinical use.
