The purpose of this investigation is to study the safety and tolerability of SENSIMED
Triggerfish, a soft contact lens-based device intended to continuously record relative
changes in intraocular pressure (IOP). The investigation enrols glaucoma patients and
glaucoma suspects. All subjects receive two 24-hour recording sessions with the device in an
ambulatory setting and at weekly interval. The level of discomfort in the study eye after 24
hours and side effects are the main endpoints of the investigation.
