Abstract

To evaluate the ease of handling of two rebound tonometers, which are designed for self-measurement of intraocular pressure (IOP) in a clinical setting by untrained patients. After self-measurement of the IOP with the rebound tonometers iCare ONE and iCare HOME, participants were asked to complete a questionnaire containing different subitems concerning ease of operation using a visual analog scale (1 = very good to 5 = very poor). Moreover, the feasibility and duration of measurement were tested. A total of 147 subjects participated in this study. The mean score for general handling ability was 2.79 +/- 1.01 for the iCare ONE and 1.85 +/- 0.87 for the iCare HOME (p < 0.001). The evaluation of the subitems sense of safety (iCare ONE: 2.71 +/- 1.03 and iCare HOME: 1.87 +/- 0.81, p < 0.001) and comfort of measurement (iCare ONE: 2.07 +/- 1.01 and iCare HOME: 1.66 +/- 0.72, p < 0.001) also showed a significant discrepancy between the two tonometers. Participants needed significantly less time for a single valid measurement when using the iCare HOME tonometer (mean 66.14 +/- 61.54 s) compared to the iCare ONE tonometer (mean 81.54 +/- 69.51 s, p < 0.001). A better handling of the iCare HOME rebound tonometer in comparison to the iCare ONE tonometer can be deduced on the basis of the subjective assessments of patients and the shorter duration of measurements. Moreover, the iCare HOME received a significantly better evaluation for all subitems. The accuracy of measurements using the iCare HOME still needs to be clarified.
