Design and Modeling of an Efficient Lens for Medical Application




An intraocular lens, known as an IOL, is a synthetic lens for the eye that replaces the natural lens after cataract surgery. An optimum diffractive bifocal IOL is modelled and made of a foldable hydrophobic acrylic polymer with distinctive optical properties (refractive index of 1.55, abbe number of 41.91), combined with its low water content to protect the interior chamber of the eye from fluid interferences. Calculations and analysis performed via Zemax-EE software yielding optimum outcomes, such as modulation transfer function (MTF), seidel aberration, spot diagram, and image simulation analysis.

In this study, a new methodology has been achieved by modeling aspheric bifocal IOL to investigate the effects of fields of view on different entrance pupil diameters throughout the visible range [0.450-0.650] μm. The optical performance system is improved by providing the finest vision correction, reducing the corneal aberration, and significantly enhancing near and far distances at 1.5mm through 20° as a general and precise treatment plans.
