Factors Affecting Measurements of IOP Using Non-Contact Eye Tonometer

Abstract

The objective measurement of intraocular pressure (IOP) represents the identification of the symptoms of some diseases, e.g. glaucoma. This objective measurement can only be achieved by correct calibration of tonometers. Today, there is no uniform methodology for this calibration. Therefore, we introduce potential sources of error and try to quantify their contributions in this paper. Subsequently, a calibration standard containing an artificial cornea with similar properties to the human one should be designed.
