Figures, The Modern Presbyopia Exam

Figure 1: In this example, the Visual Optical Transfer Strehl function(VSOTF) captured with the WaveDyn Visual Analyzer, demonstrates changes in dynamic through-focus from distance (red curve) through intermediate (green) and near (blue) reveal a total dynamic range of focus of nearly 3.0 D.

Figure 2: WaveDyn Dynamic Wavefront aberrometer through-focus curves as the patient views a target that moves dynamically from far to intermediate to near distance, the spherical equivalent (light blue dots) are stable but the pupil size (medium blue dots) is constantly changing with the target.
