Methodology for the Classification of an Intraocular Lens with an Orthogonal Bidimensional Refractive Sinusoidal Profile

The intraocular-lens (IOL) industry revolves mainly on manufacturing different types of lenses to restore the vision quality of patients through ophthalmic surgery. This paper introduces a biconvex intraocular lens with a bidimensional refractive sinusoidal profile distributed over its posterior surface. This type of pattern allows the configuration of different amplitudes and frequencies of the orthogonal sinusoidal functions, leading to different optical performance. By adjusting its parameters, it is possible to set the IOL to behave as Monofocal, Multifocal or Extended Depth of Focus. Therefore, a methodology that could assist in the classification of such lenses is proposed. The intraocular lens under test is modelled and inserted into a modified Liou-Brennan eye model. This methodology can be used as a trusted tool to help lens manufacturers in industry to determine optimal target design parameters.
