The CA model is designed for measuring chromatic aberrations of IOLs. It includes a multi wavelength light source with 4 different wavelengths. The software automatically switches between the wavelengths providing the power map at each one of them. The software uses the data for presenting the power averages, distributions, and profiles at any desired wavelength. A special analysis screen also enables the user to present the chromatic aberrations in several useful ways.

One of the IOLA Plus CA's light sources is the same green one used in the standard IOLA Plus, so that the IOLA Plus CA can function as a standard IOLA Plus when chromatic aberration measurements are not required.
