Editor’s note: The ocular response analyzer, an indentation tonometer, records intraocular pressure (IOP) twice: firstly during an increasing air pulse, and then during a decreasing air pulse. In this study, the authors modified the way these two IOPs are analyzed, in order to derive a tonometer that measures IOP independently of central corneal thickness (CCT). Testing the model on a clinical dataset (n=144) suggested that CCT indeed had reduced influence on IOP measurement. Additional validation with manometrically controlled IOP in donor eyes is the next step.
