SENSIMED Triggerfish Sensor Sizes

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01972997
Recruitment Status : Completed
First Posted : October 31, 2013
Last Update Posted : November 17, 2015

Sensimed AG

Brief Summary:
This is a study investigating the effect of various SENSIMED Triggerfish sensor lens sizes on the recorded IOP related patterns in 10 healthy volunteers. Each volunteers receives 4 24-hours sessions of pattern recording on one selected eye (study eye). Each of the sensor lens sizes is placed on the eye in the different sessions. Subjects visit the study site for installation and removal of the device and accompanying exams, but remain ambulatory during the recording.
