Numerical stress analysis of the iris tissue induced by pupil expansion: Comparison of commercial devices - Fig 3

Abstract

<p><b>The FE models and summary of the simulation parameters used in the analyses for A</b>. The iris hooks, <b>B.</b> The APX dilator, <b>C.</b> The Malyugin ring, and for <b>D.</b> Uniform circular expansion. All irides had an initial pupil diameter of 3 mm (initial shape). Following FE analysis, the deformed expanded pupil shapes had diameters of 6 mm (maximum observable diameter, expanded shape).</p
