<p>A non-invasive contact compression and refraction tonometer for measuring the intraocular pressure of the posterior chamber of the eye, measuring pressure in the posterior chamber of the eye and the vitreous chamber of the eye characterized by the fact that it is a device which measures intraocular pressure in the posterior chamber of the eye and the vitreous chamber of the eye in a compression and contract manner in relation to the walls of the posterior chamber with a double symmetrical compression element, operating concentrically, and driven by a compression actuator coupled with a newton meter, measuring the compression force necessary to deform the cornea in order to achieve the assumed corneal astigmatism level, which is measured on the cornea with an optic meter in a non- contact manner in relation to the cornea. The force of mutual impressions of the wall of the posterior chamber (compression) corresponds to the intraocular pressure in the posterior chamber of the eyeball compressed with a given force and surface in accordance with the Imbert-Fick principle.</p> |
