In different cases intraocular pressure (IOP) have to measured in lying position. Therefore a
lot of portable tonometers have been established. The Icare Pro is a new tonometer on the
market that allows faster and more comfortable IOP-measurements. No local anesthesia is
needed, what is a major advantage for the patients. In this study the investigators want to
evaluate if IOP measurements with Icare Pro Tonometer are as reliable as they are with other
established portable tonometers (Perkins, TONO-Pen and hand held-Dynamic Contour Tonometer).
