- W3091849957 abstract "The industrial sector for intraocular lenses (IOLs) is constantly searching for new lens models to improve vision quality of patients after cataract surgery. This paper presents 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. The choice of parameters enables the IOL to behave as Monofocal, Multifocal or Extended Depth of Focus. The intraocular lens under test is modelled and inserted into a modified Liou-Brennan eye model. The parameters are systematically varied and a custom methodology is employed to verify into which class a lens described by a certain set of parameters falls. After the classification algorithm, some IOLs are selected to have their performance evaluated through an image analysis that consists of different visual acuities for an object at a given distance from the eye. Also, an estimated preclinical defocus curve is simulated for those selected IOLs. This methodology can be used as a reliable tool to assist lens manufacturers in industry to evaluate optimal design parameters." @default.
