The Measurement of intraocular pressure (IOP) is a very important factor to define the presence of problems in the ocular system, an elevated IOP may indicate the presence of a glaucoma, a serious disease if not treated correctly can lead a person to blindness . The equipment used to measure the IOP is called a tonometer and has a wide variety of technologies available in the market, but the high cost ends up making it unfeasible to have diagnostic access for a large part of the population. This work aims to analyze and compare the tonometers currently in the market as well as the technology used, its operation and its main characteristics based on the following criteria: maintenance, mobility, patient positioning, need of anesthesia and eye drops, interference with the measurement of pressure. For this analysis, it is necessary to study existing sources such as books, articles, undergraduate and graduate studies related to engineering and ophthalmology areas and the operational manuals of the equipment, as well as the use of the knowledge acquired during graduation. As a result of these analyzes and comparisons it is possible to present a tonometer design using as reference the functioning and structure of the existing ones and propose improvements to obtain an equipment that has good functional characteristics combined with good precision and greater accessibility for patients.
