A collimated laser beam (543.5 nm in wavelength) is incident to an aperture stop after diffraction from an object mask (U.S. The setup consists of an artificial cornea and a wet cell containing the IOL in water between two parallel glass plates of optical quality (BK7 Schott, Southbridge, MA). In our current study, we evaluated the image quality of IOLs using field-tracing optical simulation and compared it with the image quality obtained by conventional ray tracing qualitatively and quantitatively according to the IOL misalignment.ДЄ schematic illustration of the optical simulation setup is shown in Fig 1. An essential part of this simulation technique is the propagation of harmonic fields through homogeneous media. This field-tracing approach provides simulation techniques covering everything from geometrical optics to electromagnetic field methods in a single platform. Wave optical simulation software, VirtualLab (Wyrowski Photonics GmbH, Jena, Germany), was recently developed and introduced in many areas of optics.

However, all these simulation software presented are based on ray-tracing technology.Д«y using the wave nature of light, current field-tracing technology enables optical modeling and design.

Optical simulation software like CODE V (Optical Research Associates, Pasadena, CA), OSLO (Lambda Research Corporation, Littleton, MA), or ZEMAX (ZEMAX LLC, Kirkland, WA, USA) has been used to investigate the optical quality of these IOLs, design various conditions in an optical environment, and compare results with those of an in vitro optical bench test. Numerous designs of intraocular lenses (IOLs) for specific purposes, such as spherical, aspheric, toric, or presbyopia-correcting, have been developed. In addition, field tracing of propagating electromagnetic waves allows for a much more accurate description of many optical effects and becomes necessary for small diffractive structures, which cannot be properly modeled by ray tracing.

Field tracing formulates not only the generalization of ray tracing but also of electromagnetic wave modeling. In field tracing, electromagnetic harmonic fields are traced through the optical system. It is fast but not accurate enough for simulation of most micro- and nanostructured components. Ray tracing assumes that the wavelength of light is sufficiently small so that light propagation can be described in terms of rays.

Light is regarded as a ray in geometrical optics but an electromagnetic wave in wave optics.
