Treatment and study plan

Intraocular pressure measurement with the Sensimed triggerfish Device

Device

Primary outcomes

  1. Measure of intraocular pressure while lying down

    Time frame: 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.

  2. Measure of intraocular pressure while sitting

    Time frame: 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.

  3. Measure of intraocular pressure on the eye without the lens.

    Time frame: 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.

  4. Mesure of intraocular pressure on the eye

    Time frame: One hour and a half

    Six results. Without the lens each 15 minutes. After drinking 1 L of water.

  5. Mesure of intraocular pressure on the eye without the lens each 30 minutes.

    Time frame: One hour

    Two results. After drinking 1 L of water.
