Geometric Modelling of the Human Cornea: A New Approach for the Study of Corneal Ectatic Disease. A Pilot Investigation

Abstract: The aim of this study was to describe the application of a new bioengineering graphical technique based on geometric custom modelling capable to detect and to discriminate small variations in the morphology of the corneal surface. Methods: A virtual 3D solid custom model of the cornea was obtained employing Computer Aided Geometric Design tools, using raw data from a discrete and finite set of spatial points representative of both sides of the corneal surface provided by a corneal topographer. Geometric recons… Show more

“…6) Geometric data: Correspond to information essentially describing the geometry of the anterior and posterior corneal surfaces to diagnose any pathology linked to an alteration in corneal morphology [55]. Among these data the total corneal volume, the anterior corneal surface, the posterior corneal surface, the total corneal surface, the deviation of the anterior apex and the deviation of the posterior apex [26].…”
