Primary Outcome Measures

Name	Time	Method
EP:<br>Measurement of intraocular pressure (mmHg) at a particular time using two rebound tonometer (iCare, iCare ONE), measurement with the iCare ONE tonometer is performed by the doctor as well as by the patient. Moreover, measurement of intraocular pressure is done using the Goldmann applanation tonometer and the Pascal contour tonometer.<br>Agreement of the methods is tested by using correlation and Bland-Altman plots.<br>Practicality of the new device (iCare ONE) is tested by uing visual analog scales.

Secondary Outcome Measures

Name	Time	Method
Ability of patients to meausre IOP with the iCare ONE
