This paper provides a general mathematical formula to summarize various multifocal diffractive lens designs and introduces a novel, design: the subzonal multifocal diffractive (SMUD) lens. Analytical and numerical methods of SMUD lens design are elaborated in detail. A number of trifocal and quadrifocal SMUD lens designs of high diffraction efficiency are presented. Fresnel zone spacing factors are introduced to take into account the incidence of a converging or diverging beam and the curvature of the substrate on which the diffractive surface is created. Apodization and ophthalmic astigmatism correction related to diffractive lenses are also discussed.<\/jats:p>","DOI":"10.1364\/ao.403554","type":"journal-article","created":{"date-parts":[[2020,9,29]],"date-time":"2020-09-29T08:30:42Z","timestamp":1601368242000},"page":"9807","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Multifocal diffractive lens design in ophthalmology"],"prefix":"10.1364","volume":"59","author":[{"given":"Aizhong","family":"Zhang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2020,10,26]]},"reference":[{"key":"ao-59-31-9807-R1","volume-title":"Handbook of Optics (Volume III): Vision and Vision Optics","author":"Brass","year":"2010"},{"key":"ao-59-31-9807-R2","doi-asserted-by":"publisher","first-page":"487","DOI":"10.1001\/archopht.122.4.487","volume":"122","author":"Congdon","year":"2004","journal-title":"Arch.
