Figure 2From: Selected parameters of the corneal deformation in the Corvis tonometer Examples of results obtained from the Corvis device. There are three graphs: deformation amplitude, applanation length, corneal velocity and two examples of applanation. For these two examples (1 and 2), time, length and velocity are given. On this basis and after linear calibration, the value of intraocular pressure IOP is determined.Back to article page
