Design and Analysis of Intraocular Diffractive Lens with Curved Surface

Currently, multifocal intraocular lens implantation has been widely used in the treatment of cataracts. As one of its advantages, the diffractive intraocular lens provides patients with good near and far vision. Such lenses are usually designed with a planar diffractive lens. In this example, we demonstrated how to model an intraocular lens system using a conical diffractive lens. For the actual structure and idealized grating structure, the performance of the conical diffractive lens is further studied.
