Overview
The goal of this clinical trial is to collect a comprehensive dataset of intraocular pressure values for developing a measurement algorithm for the new hand-held rebound tonometer device. The measurement algorithm shall fulfill the requirements of ANSI Z80.10:2014 standard. The study population is adults (age ≥ 18 years).
The intraocular pressure of the participants will be measured with four different tonometers.
