Ray tracing for aspheric lenses
WebJun 29, 2012 · In patients with a monofocal or multifocal aspheric IOL, the internal SA measured by iTrace, a ray tracing aberrometer, was similar to the manufacturer's designated SA in conditions of 5- and 6-mm ... WebRay-tracing an Aspheric Lens To test the intersection of a ray and the aspheric surface, we use a bracketing-based root-finding method (either the bisection or the false position method). The explicit lens definition (Eq. (1)) is incon-venient for this process, and we instead reformulate it to an implicit
