Design outcomes

Primary

Measure	Time frame	Description
Measure of intraocular pressure while lying down	30 minutes	Peak IOP defined by the maximum level reached Peak period defined by the time from the ingestion of water and the occurrence of the IOP; and Time to get back to the initial pressure, as measured with the sensimed triggerfish device. On one eye and the lens is inserted on the other eye.
Measure of intraocular pressure while sitting	30 minutes	Peak IOP defined by the maximum level reached; Peak period defined by the time from the ingestion of water and the occurrence of the IOP; and Time to get back to the initial pressure, as measured with the sensimed triggerfish device. On one eye and the lens is inserted on the other eye.
Measure of intraocular pressure on the eye without the lens.	30 minutes	Peak IOP defined by the maximum level reached; Peak period defined by the time from the ingestion of water and the occurrence of the IOP; and Time to get back to the initial pressure, as measured with the non-contact tonometer.
Mesure of intraocular pressure on the eye	One hour and a half	Six results. Without the lens each 15 minutes. After drinking 1 L of water.
Mesure of intraocular pressure on the eye without the lens each 30 minutes.	One hour	Two results. After drinking 1 L of water.
