What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Measure of intraocular pressure while lying down | 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. | 30 minutes | 
| Measure of intraocular pressure while sitting | 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. | 30 minutes | 
| Measure of intraocular pressure on the eye without the lens. | 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. | 30 minutes | 
| Mesure of intraocular pressure on the eye | Six results. Without the lens each 15 minutes. After drinking 1 L of water. | One hour and a half | 
| Mesure of intraocular pressure on the eye without the lens each 30 minutes. | Two results. After drinking 1 L of water. | One hour |
