摘要
A non-invasive contact compression and refraction tonometer to measure the intraocular pressure of the posterior chamber of the eye and / or the vitreous chamber of the eye, characterized by the fact that it is equipped with a head (1) with a compression actuator ( 5) connected by compression clamps (8) and compression arms (11) with two symmetrical compression legs (14) in the shape of a crescent, such that their curvature and contact surface with the wall of the eyeball correspond to the curvature of the eyeball beyond the corneal area, beneficially 3-5 mm towards the back of the corneal limbus (12), compressing the eyeball, beneficially in the 3 and 9 o'clock directions; It is also equipped with a compression actuator (5) connected by a two-phase connector with an optical meter (10) and a Newton meter (7) with switches (3) and (4) of the operating mode of the compression actuator ( 5) separate for each of them.
