The purpose of this study is to compare the tolerability and comfort of 4 different prototype anesthesia-free tonometer tips with the standard tonometer tip in conjunction with anesthesia. The best-tolerated prototype anesthesia-free tonometer tip will be identified for further development for home tonometry.
