Vintage Tonair Applanation Tonometer from around late 1960's to mid 1970's. The compressor is in working condition! There should be at least 2 thin surgical grade rubber or plastic tubes going from the outlets(located near the on/off switch) to the removable piece under the Tonair name. No instructions or idea if anything else is missing. This was stored under the display counter of my Father-in-Laws now closed eyeglass store for many many years and overall in pretty good condition.Please see photos for all details. From Wikipedia; Tonometry' is the procedure eye care professionals perform to determine the intraocular pressure (IOP), the fluidpressure inside the eye. It is an important test in the evaluation of patients at risk from glaucoma Applanation tonometry In applanation tonometry the intraocular pressure is inferred from the force required to flatten (applanate) a constant area of the cornea, for the Imbert-Fick law.[2] The Maklakoff tonometer was an early example of this method, while the Goldmann tonometer is the most widely used version in current practice.[citation needed] Because the probe makes contact with the cornea, a topical anesthetic, such as proxymetacaine, is introduced on to the surface of the eye in the form of an eye drop.
